In the Romance of the Three Kingdoms, how was the east wind formed in the Battle of Chibi?
It was indeed a southeasterly wind that day. But it was not borrowed by Zhuge Liang, but a coincidence. According to historians' research, the Puqi Red Cliff now located on the south bank of the Yangtze River in Hubei Province is the most "authoritative" Red Cliff. In Hubei Province, it is not uncommon to have southeasterly winds in winter.
(Having said that, even in the north, the northwest wind does not blow every day)
This wind was only blown by Liu Bei and Zhou Yu (history books indicate that during the Battle of Chibi, Zhuge Liang and (not on the front line) is just a favorable situation achieved. A very important point is that Cao Cao's soldiers were not burned back. The main reason was that the plague among Cao Cao's troops caused a decline in combat effectiveness. That fire was just a boost.
Red Cliff is in the middle reaches of the Yangtze River in eastern Asia. In winter, the land cools faster than the ocean, so cold high pressures often form in central Asia, such as the Siberian High. In this way, the northwest wind should prevail in the Chibi area at that time.
1. Since the atmospheric movement is complex and changeable, it is likely that a small low pressure accidentally appeared in the west of the Chibi area. Low pressure in the Northern Hemisphere is a cyclone, with air flowing in counterclockwise. In this way, the southeasterly wind blows from Chibi in the eastern part of the low pressure.
2. It is also possible that a small high pressure appeared east of Red Cliff. The high pressure in the Northern Hemisphere is anticyclonic, with air flowing out clockwise. In this way, the southeasterly wind blows just right in the Chibi area in the western part of the high pressure.
So, the truth about "borrowing" the east wind is actually:
A small high pressure formed to the west of Chibi and gradually moved eastward. When this anticyclone passes through the Chibi area, the area will be affected by it, causing heavy fog at night and fine weather during the day. When this anticyclone moves to the east of the Chibi area, southeasterly winds prevail in the Chibi area. The east wind is also "borrowed".
