What's the relationship between weather and changeable weather?
When Cao Cao attacked Jingzhou, Liu Bei and Sun Quan formed an anti-Cao alliance. Sun Quan's general Zhou Yu was very jealous of Liu Bei's strategist Zhuge Liang and wanted to kill him. He asked Zhuge Liang to make 100,000 arrows in ten days and issued a written military order. If he can't make these decisions in time, he will engage in military law. Zhuge Liang skillfully used the fog of the Yangtze River to drum and shout in front of Cao Ying with dozens of boats tied with scarecrows at night. Cao Jun shot an arrow, but all the arrows were aimed at the scarecrow. Zhuge Liang got more than 100 thousand arrows without blowing off dust. Zhuge Liang and Zhou Yu made a plan to attack Cao Cao with fire. However, the northwest wind has been blowing on the river for several days, and the fire attack will not only burn Cao Bing on the north shore, but will burn himself. Zhou Yu was depressed by the east wind and was ill in bed. After Zhuge Liang knew it, he wrote a prescription to Zhou Yu. Zhou Yu opened it and read: "If you want to break Cao Bing, you should attack it with fire. Everything is ready except the east wind. Zhou Yu admitted that his mind was guessed by Zhuge Liang and asked Zhuge Liang what he could do. Zhuge Liang said that he could borrow the east wind, so he asked Zhou Yu to build a nine-foot-high seven-star altar for him and then do it himself. A few days later, as expected, the southeast wind blew. Zhou Yu felt that Zhuge Liang could not stay any longer, so he sent someone to kill Zhuge Liang at the Seven Star Altar. But Zhuge Liang had long expected that Zhou Yu would have this skill, leaving the Seven Star Altar ahead of time and returning to his base area, Xiakou. Before leaving, I left a message for Zhou Yu: "I hope Governor Zhou can make good use of this wind to defeat Cao Bing, and Zhuge Liang will return to Xiakou for the time being and meet you another day." Zhou Yu had to give up.
Clever use of the wind direction, so success.
You can also give examples, such as the relationship between weather and farming activities. The natural law of spring planting and autumn harvest, the need of precipitation and temperature. Both are fine ~
