Interpretation of Yu Yang Qi Hou Qin Ji (Intimate Observations of Rain and Sunshine Weather Patterns)
Solar Observations
At dawn before sunrise, observe the eastern sky:
- If dark clouds resembling eggs, banners, mountains, crows, dragon heads, serpent-fish, lingzhi mushrooms, or peonies appear, thunderstorms will occur between the wei and shen hours (1–5 PM).
- Purple-black clouds piercing the sun or positioned above/below it indicate thunderstorms that same day.
- Scaly dark clouds foretell winds and thunderstorms within three days.
Lunar Observations
- A reddish moon signals heavy thunderstorms the next day; bluish-red hues indicate rain.
- A halo the size of a cartwheel predicts strong winds in three days.
- A faint halo suggests winds will arise the following day.
Celestial Pivot Star (Tiangang, the Big Dipper's Handle)
- If Tiangang appears reddish and trembles, thunderstorms approach; a bluish tremor signals severe weather the next day.
- White clouds near the star indicate major thunderstorms, while yellow clouds crossing Wenqu (the 4th star of the Big Dipper) also presage storms.
- White clouds emerging from the Dipper's center foretell thunderstorms during the wei hour (1–3 PM) the next day; clear skies imply calm weather.
Big Dipper (Beidou) Observations
- White clouds obscuring the Dipper predict significant weather shifts by the wei-shen hours (1–5 PM) the next day.
- Scaly clouds around the Dipper similarly signal abrupt changes.
- Two or three stars veiled in white clouds indicate heavy thunderstorms.
- Wavy white clouds near the Dipper mean strong winds the next day; scattered fleecy clouds suggest milder winds.
- Black clouds rising beneath the Dipper bring wind and rain that night; purple-black mist at the Dipper's mouth foretells storms in three days.
- Bluish clouds correlate with Wood-element days (Jia/Yi), red hues with Fire-element days (Bing/Ding).
- Yellow/white/black clouds crossing the Dipper bring heavy rain within three days or immediately.
- Lightning below or at the Dipper's mouth guarantees rain that night.
Dragon Qi (Dragon Energy)
At dawn in the east:
- Thin, multicolored strands of Qi drifting westward mean wind and rain that day.
- Clouds lingering motionless at the zenith will manifest as weather shifts by dusk three days later.
- Multicolored layered Qi at sunset in the east fulfills within three days.
White Tiger Qi
White Qi masses near the sun in the early morning (yin hour, 3–5 AM) signify the White Tiger constellation's influence, heralding impending wind and rain.
This scripture primarily discusses methods for predicting thunderstorms by observing cloud formations, along with celestial omens associated with the thunder deity "Chuhuo" (a title of Marshal Deng Xie, commander of the Daoist Thunder Department). Here's a plain explanation:
[Cloud Observation Methods]
- Specific cloud patterns appearing during the Shen hour (3-5 PM) or Si hour (9-11 AM) indicate thunderstorms the next day between the Wei and Shen hours (1-5 PM)
- Dark, patchy clouds resembling pigs crossing a river or tattered cotton wool, whether obscuring the moon or appearing beneath it, foretell thunderstorms the following day
- White cotton-like clouds predict light rain, while clouds moving from south to north indicate southerly winds the next day
[Thunderstorm Omens]
1. High-altitude dark clouds ("Thunder Signals") appearing in the southern sky at dawn will dissipate by the Si-Wu hours (9 AM-1 PM), signaling rain between Wei-Shen hours (1-5 PM)
2. The direction from which clouds appear at higher altitudes indicates the approaching storm's path
[Thunder Deity's Celestial Signs]
When Marshal Chuhuo takes action, these unusual phenomena occur:
- Sudden gales and torrential thunderstorms during the You hour (5-7 PM), strong enough to uproot trees
- Signs appearing during Shen-You hours (3-7 PM) will manifest as thunderstorms by the Zi hour (11 PM-1 AM)
- Sunrise clouds shaped like rooster heads or banners guarantee fish-scale patterned rain by Wei-Shen hours (1-5 PM)
- Dark clouds resembling dragons, snakes, or lingzhi mushrooms similarly predict thunderstorms
[Warning Signs]
When Chuhuo appears simultaneously with the "Golden Tiger" (western malignant force):
- Deadly thunderstorms will strike the next day, potentially destroying temples and harming people/livestock
- Sky darkens with flying sand and stones, trees torn up by roots
- Directional omens: most dangerous when appearing in Qian (NW), Xun (SE), or Gen (NE) sectors; relatively milder in Li (S) and Dui (W) sectors
[Extreme Thunderstorms]
- "Red Rooster Purple Goose" thunderclouds bring lightning strong enough to split trees
- When the Thunder Department transforms into water, torrential rain pours instantly
- Sandstorms with lightning during Wei-Shen hours (1-5 PM) often accompany temple destruction and other disasters
Note: These observation methods originate from Daoist Thunder Ritual traditions, connecting natural phenomena with divine activities—a fusion of ancient weather prediction and religious cosmology.
This scripture describes the correspondences between celestial phenomena and human calamities, focusing primarily on the natural manifestations and punishments enacted when thunder deities like "Swift Fire" (Chu Huo) patrol the mortal realm. The interpretation is organized as follows:
1. When the Swift Fire deity dispatches the "Golden Tiger" (a thunder beast) to deliver divine commands:
- If solar halos appear between 9 AM-1 PM (Si-Wu hours) encircled by dragon- or serpent-shaped clouds, torrential thunderstorms will strike the southeast within three days
- This destroys illicit shrines and executes wicked individuals
2. When Swift Fire converges with the "Great Unity" (Taiyi, the North Star deity):
- Omens appearing on the first day bring violent storms on the next
- Lightning strikes evildoers, temples collapse, and trees are uprooted
3. Other common celestial portents:
- Cloud formations stretching thousands of feet like curtains foretell severe droughts and hurricanes
- Overcast skies with sudden thunderstorms between 1-5 PM (Wei-Shen hours) exterminate shape-shifting demons
- Crimson cloud vapors ("Red Rats") drifting over city walls predict southern disasters within five to six days
- Cloudless Milky Way during prolonged drought signifies celestial decree—prayers prove futile
4. Seasonal phenomena:
- Winter thunderstorms during snowfall mark the Thunder God's inspection tour
- "Fire Bell General" (a flame deity) manifesting between May-July (lunar calendar) heralds extreme droughts
- Frequent serpentine lightning in spring presages windstorms in June-July
5. Concerning patrols by "Lord Xin" (another thunder general):
- When appearing simultaneously with the "Golden Tiger Executioner," moon-veiling serpentine clouds materialize abruptly from clear skies
- Three-directional thunderstorms between 1-5 PM the next day demolish temples and smite evildoers
- Moon obscuration during 11 PM-3 AM (Zi-Chou hours) invites summer locust plagues
These records embody the Daoist cosmology of "Heaven-human resonance," viewing extraordinary celestial events as divine responses to human morality—particularly punishments targeting improper folk shrines and wicked individuals. The "temple destruction" specifically refers to demolishing unauthorized cultic sites, while "executions" denote thunderous retribution against grave sinners.
This scripture primarily describes various omens of thunderstorms and celestial phenomena accompanying the inspections of thunder deities. Here is the modern interpretation:
When thunderstorms occur before the Shen hour (3-5 PM), they are often accompanied by lightning strikes.
When Xinjun (a thunder general) patrols the moon palace, if black clouds resembling snakes enter from the western (Dui) position, heavy rain will surely fall within three days. When thunder envoys (deities executing thunder rites) and the Five Qi Thunder Gods (deities governing thunder from five directions) conduct inspections, severe thunderstorms will arrive during the Wei-Shen hours the following day.
When thunder envoys meet with the Dipper's Water Envoy (deity governing water domains), lightning will strike trees, slay evil spirits, and harm humans or livestock during Wei-Shen or Xu-Hai hours (7-11 PM) the next day. When the Tiangang star (one of the Big Dipper stars) drives away baleful energies, heavy thunderstorms will certainly occur within a day or two.
When the white-clouded Wind God pays homage to the Dipper, sandstorm-level gales with thunderstorms will arise the following day. During inspections by thunder envoys and thunder masters, fierce storms with demon-slaying lightning will surely come. If they meet with water palace deities, thunderstorms are inevitable the next day.
When the Ziwei star (Polaris) inspects the human realm, rain will fall within three days. When Tiangang meets the Taiyi deity (North Pole deity), within seven days torrential rains will turn land into rivers, with lightning destroying temples and slaying spirits.
When black qi resembling clouds appears during Taiyi's palace transition, or when black clouds obscure the Dipper, rain will come that night. If misty wind-thunder rushes directly toward the Dipper during Wei-Shen hours the next day, this likewise foretells heavy rain.
Blue radiance indicates prolonged drought—this is an inauspicious time for rain prayers, and insect plagues will follow. If envoys (thunder gods) appear as black pigs crossing rivers or approaching in formation, heavenly flood-level downpours will arrive during Wei-Shen hours the next day. When Xuhuo (a thunder general) spreads its wings, severe thunderstorms will come during Shen-You hours (3-7 PM) that same day.
The scripture concludes with signs of different thunder types:
- Heaven's Thunder: Originates from southeast (Xun) or northeast (Ghost Gate), with deep rumbles penetrating the earth
- Xuhuo Thunder: Clouds shaped like phoenix wings or fish scales, initially cyan then turning black
- Divine Thunder: Resounds from the east
- Xun Thunder: Clouds approach from east/southeast in straight formations, unleashing storms upon reaching the zenith
- Water Thunder: Clouds surge upward in wavelike patterns
(Note: Directional terms like "Dui" and "Xun" correspond to the Bagua positions—west and southeast respectively)
This scripture primarily explains methods for predicting wind, rain, thunder, and lightning through observing cloud formations, along with related astrological divination techniques. Here is the simplified interpretation:
[Cloud Observation Section]
When the following cloud patterns appear, storms will arrive shortly:
1. When the Grand Year Thunder (a specific thunder deity) descends: The sky will show extremely dark clouds with faint white edges, shaped like brush tips. Shortly after these clouds appear, violent thunderstorms with strong winds will erupt.
2. When the Earth Deity Thunder manifests: The clouds appear dark black mixed with pinkish-white patches resembling painted patterns. Whether these clouds emerge in clear or overcast skies, they foretell severe wind and rain lasting about seven days before stabilizing.
[Astrological Divination Section]
This lists seven lunar mansions (such as Xu, Kui, Bi, etc.) and their corresponding celestial stem-branch combinations that may trigger weather changes. For example:
- When the Xu mansion aligns with stem-branch combinations like Jiazi or Gengzi
- When the Kui mansion aligns with Jiazi or Guiwei
(Note: These terms refer to specialized calendrical and astronomical correlations in ancient systems.)
[Special Meteorological Phenomena]
Describes various weather omens:
- Phrases like "Yin-Yi waves" indicate specific stem-branch combinations that may cause surging waves or fiery phenomena.
- "When the Fang, Zi, and Shi mansions glow red fourfold": If these lunar mansions appear crimson, floods may follow.
- "When Kang and Ji transform into dragons": Cloud formations resembling dragons emerge during changes in these mansions.
[Principles of Cloud Movement]
Concludes with patterns of cloud manifestation:
- When black Qi rises in the east, cloud formations will repeatedly open and close.
- Heavy, dim clouds gather in the western sky at dusk.
- Pale-colored clouds demand attention—if they intersect with watery or yang Qi, they expand like winnowing baskets, heralding weather shifts.
(Note: These are esoteric Daoist techniques for weather prediction, synthesizing celestial phenomena, stem-branch cycles, and cloud formations—part of traditional meteorological divination arts.)
This scripture primarily elucidates the ancient Daoist mysteries concerning weather patterns, rain-summoning rituals, and the formidable powers of the thunder deities. Here's a section-by-section explanation:
Weather Omens:
- When majestic cloud formations appear (首气雄豪), neither humans nor livestock can escape impending conflict
- The sight of black-and-red clouds accompanied by thunder (怒气黑红兼叱咤) signals approaching wind and rain
- Specific weather patterns manifest when the Big Dipper's celestial configuration shifts (北斗自上乌飞下)
Thunder Deity System:
- "Taiyang" (the Great Yang) represents the deity of sudden lightning (欻火之神), while "Taiyin" (the Great Yin) signifies the fierce commander governing wind and rain (都督猛吏之神)
- Special mention is made of "雷首欻火律令君", known as the Great White Tiger Spirit of Destruction, capable of pulverizing even diamond-hard resistance
- The appearance of dragon-shaped black Qi (日傍黑炁如龙现) near the sun foretells violent storms
Rain-Summoning Ritual Essentials:
- Successful rain invocation requires harmonizing inner alchemy (内在修炼) with cosmic patterns (自然规律)
- References the drought-causing "旱魃之神" deity
- Mentions specialized "雨师" (Rain Masters) whose firm footing (雨师立脚重如山) heralds imminent thunderstorms
Weather Observation Wisdom:
- When clouds traverse the sun east-to-west (东升西入云贯日), rain falls during the Xu, Hai, Wei, or Shen hours
- Crimson rooster and purple goose-shaped cloud formations signal same-day thunderstorms
- Drought years demand particular attention to Rain Masters' movements
This scripture synthesizes astronomical observation, deity worship, and Daoist cultivation methods, demonstrating ancient wisdom in weather prediction through natural phenomena and attempts to influence weather through religious rites. Terms like "欻火" (sudden fire) and "律令" (divine command) represent key concepts in Daoist thunder magic, denoting different thunder deities and ritual powers.
This scripture describes methods for predicting natural phenomena like wind, rain, thunder and lightning through celestial observations, along with related exorcism techniques. Here's a detailed explanation:
When storms occur during the Wei (1-3pm) and Shen (3-5pm) hours, this signifies heaven's execution of demons. Thunder will then strike and destroy corrupted altars and temples.
Lightning flashing through clouds resembling black boars spitting fire indicates the Thunder Gods eliminating spirits during Wei-Shen hours. Severe cases bring thunderbolts, while frost and snow appear in the ninth and tenth lunar months. If summer brings crimson clouds towering in southern skies without entering the Milky Way (Tianhe), expect eighty-one days of drought.
Overcast frost on Jia-Shen or Bing-Zi days foretells light rain. During Hai (9-11pm) to Zi (11pm-1am) hours, observe quietly - dark clouds crossing the Milky Way ("black ox fording the river at midnight") plus obscured stars and moon signal approaching storms.
Clear skies on Liu-Jia days (Jia-Zi, Jia-Xu etc.) predict severe drought. Red dragon-shaped clouds (chi-long) on Ren-Zi or Ding-Si days with sparse stars in the Milky Way also indicate drought. Morning clouds resembling unfurled black banners are ominous.
Solar halos during Si (9-11am) and Wu (11am-1pm) hours with dragon/snake-shaped clouds mean thunderstorms within three days. Anomalies in the southeast foretell the punishment of evil spirits, with ancient trees and corrupted shrines being purged.
When the waning moon (Taiyin) passes the Xun (southeast) position, wind and rain will follow next day. Lightning strikes punish evildoers and execute demon-possessed livestock. Simultaneous sun-moon passage through Xun creates the "Qianjing Great Execution Deity" phenomenon, bringing earth-shaking storms within three days.
Clouds covering the sun like sunset glow or endless curtains - called "E Bo" (ancient fire god) - bring thunderous gales during Wei-Shen hours. Sudden dark clouds with dragon-shaped red halos that briefly obscure then reveal the sun indicate the "Thunder Vanguard Execution Deity" - rain follows within two days, with gales uprooting trees as evil spirits are punished.
During droughts, observe Jupiter's ("Mu Lang") movement and calculate positions of pivotal stellar deities ("Shuji Shensha"). Two foot-shaped clouds moving along mountains guarantee drought. Isolated clouds in clear skies mean rain within three days. Wind-snapped trees signify demon executions, while unfilial people receive livestock-like punishments. Scattered clouds predict strong winds; dense fog obscures sun and moon.
This scripture primarily discusses how to predict weather phenomena like wind, rain, thunder, and lightning by observing celestial changes, along with the auspicious or ominous signs these phenomena portend. Here's a plain explanation:
When thunder and lightning suddenly appear in the sky, widespread storms will soon cover mountains and rivers. If fog obscures the heavens like a coiling dragon, especially during the Wei (1-3 PM) and Shen (3-5 PM) hours, it often foretells impending wind and rain.
Cloud formations at different times predict varied weather:
- Clouds encircling Chen hour (7-9 AM) during Yin day (3-5 AM) indicate coming rainfall
- Clouds obscuring the sun at dusk in the northwest mean heavy rain within the month
- Dragon-horse shaped clouds in the southeast bring wind and rain that very day
- Goose-flock formations approaching from the northwest predict rain during Shen-You hours (3-7 PM) within three days
Cloud colors and shapes hold significance:
- Thick black clouds accompany strong winds and thunder
- Mountain-like or beast-shaped dark clouds bring thunder before rain
- Heavy mountain fog means thunderstorms within three days; light fog foretells heavy rain within seven
- Banner-shaped clouds at dusk predict wind, rain, and lightning during Wei-Shen hours
The text notes special phenomena:
- Rainbows around the moon (lunar halos) are inauspicious signs
- Specific celestial phenomena during Xu-Hai (7-11 PM) or Zi-Chou (11 PM-3 AM) hours in spring/winter bring severe cold, hail, or frost
- The moon passing through Wei constellation (one of the 28 lunar mansions) appearing dragon-like causes disease and torrential rain
- Moon transiting Bi constellation brings storms; dark moons presage misfortune
Finally, it mentions "Jinhu Sha" (a weather-controlling deity) and "Taiyin's Mansions" (the moon's stellar positions) determine fortune. Prayers can be made for clear skies or rain. Yet the text satirizes those who ignorantly draw talismans without understanding these mysteries.
This scripture primarily explains how to predict weather phenomena like wind, rain, and thunderstorms by observing celestial patterns, cloud formations, and stellar configurations, along with the auspicious or ominous signs these natural manifestations convey. Here's a simplified interpretation:
Reading weather through celestial signs:
- When the sun and moon appear dim and lackluster, expect impending wind and rain
- When the Ji and Bi constellations (two of the twenty-eight lunar mansions) surround the moon, strong winds will follow
- The hours of Wei (13-15) and Shen (15-17) are particularly prone to thunderstorms and torrential rain
Special celestial omens:
- If misty qi resembling a dragon encircles the moon during Zi (23-1) or Chou (1-3) hours, heavy rain will fall on the Chou day
- Should no rain come, major flooding may occur during Yin (3-5) or Mao (5-7) hours
- When dark clouds pierce through the Lianzhen star (one of the Big Dipper's seven stars), lightning strikes may harm people within three days
- White clouds traversing the Tanlang and Jumen stars (both in the Big Dipper) bring strong winds without rain, followed by clearing skies
The Big Dipper's significance (venerated as Daoist stellar deities):
- The Fire-Thunder Deity and Northern Dipper Star Lords hold the keys to determining fortune and misfortune
- Known as the "Great Yin-Yang Executioner Deities," they govern human karma and retribution
- They manifest through cloud formations, rainfall, and lightning strikes to punish evil deeds
Cloud formation prophecies:
- Turtle-shaped black clouds breaking through the Pojun star (Big Dipper) foretell seven consecutive days of rain, potentially causing floods
- Crimson qi entering the Dipper constellation brings mild wind and rain, or severe thunderstorms
- White clouds shooting across the Big Dipper warn of disastrous thunderstorms
Observation essentials:
- Carefully monitor meteorological changes across the twenty-four solar terms
- Study subtle signs within the seventy-two pentads (ancient five-day weather cycles)
- During perfectly clear nights with balanced yin-yang energy, even ritual talismans lose efficacy
- Meticulously calculate the Southern and Northern Dippers' positions to discern auspicious and inauspicious stellar influences
Other special omens:
- When the five planets (Venus, Jupiter, Mercury, Mars, Saturn) emit pure light, a ten-day drought may follow
- Unusually bright Bi constellation signals ineffective prayers, heralding locust plagues and human calamities
- Thunder or snow around the winter solstice constitutes abnormal celestial phenomena
(Note: The referenced time periods and constellations belong to ancient astronomy. Daoism considers these celestial changes intimately connected with human fortunes, allowing practitioners to predict weather and discern blessings or misfortunes through such signs.)
This scripture describes ancient methods for predicting weather patterns and droughts by observing natural phenomena. Here's a plain explanation:
When thunder occurs in any location, it's generally an inauspicious omen, regardless of direction. If Mars (the "Sparkling Deluder" in ancient astronomy) appears in the southern sky, all vegetation will wither. When stars glow red in a particular direction, drought will follow—the intensity of the red halo indicates the degree of fortune or misfortune.
When Mars moves near the Ji and Bi lunar mansions (two of the twenty-eight constellations), expect wind and rain; near other constellations, drought is likely. Regularly observe wind and cloud movements on the six Jia days (from the traditional Heavenly Stems and Earthly Branches calendar). Understanding these signs brings clarity. Particularly during mid-autumn, diligent morning and evening observations are crucial—if stars appear sparse in the sky, drought approaches.
Other natural indicators include:
- Damp stones and turbulent water foretell rain
- Rising steam signals impending rainfall
- Bubbles rising in water, fish leaping, and ants sealing their nests all indicate coming rain
- Spotting a centipede crawling by day means wind and rain will arrive between 1-5pm the next day
- A rainbow in the west brings rain that same day
- For eastern rainbows, observe cloud height—clouds without rain signify drought caused by the drought demon (a legendary creature)
Patterns of Qi (vital energy) movement between heaven and earth:
- When earthly Qi rises, rain falls within three days
- When heavenly Qi descends, continuous rain follows
- If heaven and earth Qi fail to interact, drought occurs
Seasonal weather patterns:
- Summer omens foretell rainless autumns
- Spring signs predict seven days of continuous rain
- Summer rain in the north brings autumn rain in the south
- Winter south winds bring snow; prolonged rain stops when west winds blow
The text concludes by revealing its extraordinary origin—this secret classic was transmitted by the Celestial Worthy of Primordial Beginning (Yuanshi Tianzun, the supreme Daoist deity) and is only accessible to those with profound Daoist roots and destined affinity. It contains thunder magic techniques for summoning wind and rain and acting on heaven's behalf, but transmission requires utmost caution—only the virtuous and morally cultivated may receive it. This knowledge should be treasured and used judiciously to benefit humanity.
