Why is the average temperature of 5438+00 in June in Hanzhong lower than that in Xi 'an?

The reason is influenced by the autumn rain in West China.

Southwest China is easily affected by the autumn rain in West China from August to June every year, 5438+ 10. In rainy weather, the atmosphere has a strong weakening effect on solar radiation, and the temperature is low. Hanzhong is located at the southern foot of Qinling Mountains, and it will be affected by the autumn rain in West China in June+10 in 5438. The average temperature in Hanzhong is obviously lower than that in Xi, so Hanzhong is most vulnerable to the autumn rain in western China.

The factors that affect the temperature are the degree of knot, the location of land and sea, the nature of underlying surface, weather conditions, frontal activity, topography, ocean currents, vegetation and human factors.
