How does Zhuge Liang study the weather?

Zhuge Liang famously introduced his experience of communicating with Lu Su after "borrowing an arrow from a straw boat": he was a mediocre man who knew nothing about the weather, geographical location, strange doors, yin and yang, war maps and military intelligence. Zhuge Liang calls himself "Wolong" and often compares himself with Guan Zhong, Le Yi and Liu Bei who just came out of the mountain. Of course, he is not mediocre. He used soldiers all his life, whether it was the right time, the right place, the strange door, the yin and yang, the array and the military situation, all of which can be said to be handy. Especially in the absence of modern satellite cloud pictures to refer to, he used night sky observation, yin and yang gossip and Taoism to predict the "weather forecast" with an accuracy rate of 80%

Zhuge Liang's first "weather forecast" was in the battle of "burning a new field" Cao Cao personally led a million-strong army to chase Liu Bei to Xinye County, and sent Coss, Cao Hong and Chu Xu as the front lines. Zhuge Liang divided his forces and rejected the enemy Cao Bing, saying, "Cao Jun will enter the city and rest in his private house. There will be a strong wind after dusk tomorrow.". But looking at the wind direction, we let three ambushes in the west, south and north shoot rockets into the city ... Is Zhuge Liang accurate? "Romance of the Three Kingdoms" wrote: "After the first shift, there was a strong wind ..." Later generations lamented that Cao Cao, the treacherous hero, defended the Central Plains in September and marched south to Hanchuan. Fengbo is angry in Xinye County, and Zhu Rong flies under the flame. Zhuge Liang predicted that "there will be strong winds after dusk in the future", and Fengbo helped Liu Bei's army defeat Cao Jun. ..

Zhuge Liang's second "weather forecast" is the famous "grass boat borrows arrows" Zhou Yu was jealous of Zhuge Liang's talent and wanted to harm him with a trick. He ordered him to make 10 arrows in 10 days. Zhuge Liang said that it could be built within three days and the written evidence was established. Why is Zhuge Liang so sure? After he succeeded in "borrowing an arrow", he explained to Lu Su: "It was decided three days ago that there would be heavy fog today, so he dared to allow it for three days." Zhuge Liang predicted three days of foggy weather, and the artist was bold. He only used dozens of pawns to "borrow" 100,000 eagle and feather arrows from Cao Cao, and he is worthy of being a hero of the Three Kingdoms!

Zhuge Liang's third "weather forecast" was a famous "borrowing from the east wind" in the Chibi War. Zhou Yu has everything, except for the east wind to break Cao. From this point of view, although Zhou Yu is a famous Soochow player, he is not as good as Zhuge Liang in "weather forecast". Zhuge Liang's so-called "taking advantage of the situation" is actually the result of his accurate "weather forecast" Regarding "borrowing the wind", he explained to Zhou Yu: "Although Liang has no talent, he has met strangers, taught Daoism, and is able to call the wind and rain. ..... bright on the stage, borrow the southeast wind for three days and three nights to help the governor fight, how? " , "1 1 How about Jiazi Festival on the 20th, 1 1 Bingyin Festival on the 22nd?" If Zhuge Liang has magical powers, when can he borrow the wind? He wants to set a date in advance, which is obviously a bluff, fooling people like Zhou Yu who don't understand the weather forecast. This time Zhuge Liang has predicted strong winds for a long time.

Zhuge Liang's short-term, medium-term and long-term weather forecast is very accurate, which is better than the weather forecast released by CCTV with satellite cloud pictures now, but sometimes the forecast like CCTV is not very accurate. Zhuge Liang's prediction of the weather is not foolproof, and he can do nothing about the sudden change of the weather. Just like one day in June, there was no cloud in Wan Li, suddenly there was a thunderstorm, suddenly there was a storm, and then it was sunny. This kind of prediction is even helpless for the gods.

Zhuge Liang finally fought to the death with Sima Yi and caught up with this weather. According to Zhuge Liang's habit of predicting the weather every time he fights, Zhuge Liang predicted that there was no cloud in Wan Li in the "World War I in Shanggu" with Sima Yi, so he designed to surround Sima and his son in Shanggu and wanted to burn them. Unexpectedly, something unexpected happened in the sky. To Zhuge Liang's surprise, just as he was about to achieve great success, there was a sudden strong wind, black air, lightning and thunder, and heavy rain. The fire in the valley was all burned out, the mines stopped shaking, the firearms were out of order, and Sima and his son lived in death. Zhuge Liang sighed angrily: "Man proposes, God disposes." Don't be strong Later generations have a poem sighing: "Taniguchi is surging, flames are drifting away, when will the shower fall?" "If Wuhou's coup can be realized, Andeshan River will belong to the Jin Dynasty!" This shows that Zhuge Liang's prediction of "weather forecast" is sometimes inaccurate!
