Jianyang perennial wind direction

Sichuan basin is located in the southeast of Qinghai-Tibet Plateau, and the weather is influenced by plateau topography and thermal effects, 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 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 produce more static wind.

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 topography in Sichuan, the wind direction in some areas will also be affected by the canyon topography, such as the canyon area.

Pollution problems can be seen everywhere in the mainland. The so-called environmental protection is for foreigners. There are chemical plants, cement plants and printing and dyeing plants near here. The government only cares about GDP, so it doesn't care about your environment.
