What winds blow in Sichuan in winter? For example: southeast wind

Personally, I feel that there are not many windy times in Sichuan.

Sichuan basin is located in the southeast of Qinghai-Tibet Plateau, and the weather is influenced by plateau topography and thermal action, as well as basin topography and local topography.

Sichuan basin is influenced by plateau topography and controlled by southwest vortex (low pressure), which is a counterclockwise low pressure vortex around the basin, with different wind directions in different parts, such as the south wind in the east and the north wind in the west of the basin.

Affected by the thermal effect of the plateau, the plateau is a thermal depression in the second half of the year, the Sichuan Basin is located in the southeast of the thermal depression, and the prevailing wind is southwest wind. In winter, the plateau is extremely cold, and northerly winds prevail in the basin.

The effect of the basin itself on the wind direction is generally to reduce the wind speed, and there are many static winds.

The summer rainstorm in Sichuan basin is controlled by subtropical jet, western Pacific subtropical high and equatorial convergence zone, and the wind direction is mainly southwest wind, south wind and southeast wind.

Due to the complex local terrain in Sichuan, the wind direction in some areas, such as the canyon area, will also be affected by the canyon terrain.
