What is Zhuge Liang's principle of borrowing from the east wind?

The truth of "borrowing" from the east wind is actually that a small high pressure forms west of Chibi and gradually moves eastward. When this anticyclone passes through Chibi area, Chibi area is affected by it, which is foggy at night and sunny during the day. When the anticyclone moved to the east of Chibi area, the southeast wind prevailed in Chibi area under its action. Dongfeng also "borrowed".

To sum up, there are two possibilities:

1. Due to the complex and changeable atmospheric movement, it is likely that a small depression will occasionally appear in the west of Chibi area. The low pressure in the northern hemisphere is a cyclone, and the airflow flows counterclockwise. In this way, the southeast wind just blows to Chibi in the east of the low pressure.

2. It is also possible that there is a small high pressure east of Chibi. The high pressure in the northern hemisphere is an anticyclone, and the airflow flows clockwise. In this way, the southeast wind just blows in the Chibi area in the west of the high pressure.

Borrowing East Wind

Romance of the Three Kingdoms is a novel. Later generations have two views on borrowing the east wind from Zhuge Liang's altar:

On the one hand, it is believed that Zhuge Liang used the east wind to make magic in the book, and the author sorted it out and created a resourceful character image;

On the other hand, in fact, the book does not directly say that Zhuge Liang used magic to borrow the east wind, but predicted that there would be an east wind with rich meteorological knowledge, so Zhuge Liang just put on airs on the seven-star altar, pretending to use magic and shocking Jiangdong at the same time.
