The new curriculum standard national volume 1 geography first question Panzhihua first question! Be sure to speak in detail, my geographical foundation is not good!

Causes of high temperature in Panzhihua in June+10, 5438:

1. The terrain is blocked, and it is less affected by cold air (cold wave) in the north in winter.

2. Located in the valley of the river (Jinsha River), the mountain is high and the valley is deep, and the downstream flow prevails, and the airflow increases during the sinking process.

Weather characteristics of Panzhihua in January

More sunny days, less clouds and rain, weak wind, high and stable temperature (small fluctuations)

Saint Liang Xiao questioned this argument.

Iron and steel industry and other industries, urban transportation and so on discharge a lot of waste gas;

2. The terrain (high mountains and deep valleys) is relatively closed, and the downward flowing air is stable (prone to inversion), which is not conducive to the diffusion and dilution of pollutants in the air.

Hope to adopt, thank you!
