Cause of strong wind in Shanghai

Because Shanghai’s climate conditions are subtropical monsoon climate. The overall climate characteristics of the subtropical monsoon climate are hot summers and warm winters, four distinct seasons, rain and heat in the same period, and a developed monsoon. Shanghai is located in the subtropical coastal area. In summer, affected by the difference in temperature between sea and land, the southeast wind blows. In winter, affected by the cold wind from Siberia, the northwest wind blows. The two take turns to control, with seasonal alternation, and the declination angle exceeds 120 degrees, forming the monsoon. .

The value of subtropical monsoon climate:

Subtropical monsoon climate (Subtropical Monsoon Climate), also known as subtropical monsoon climate, is a non-periodic weather controlled alternately by tropical ocean air masses and polar continental air masses. It is a mid-latitude monsoon climate type with significant sexual changes and seasonal changes in precipitation. The subtropical monsoon climate is characterized by rain and heat at the same time and warm winters, and the products are relatively abundant. Rice is widely grown, and it has high-yield commercial grain bases such as the Yangtze River Delta, Jianghan Plain, Poyang Lake Plain, Dongting Lake Plain, Pearl River Delta, and Chengdu Plain. Corn is also grown in large quantities in some mountainous areas. Oil crops were promoted, and tea grown has been an important beverage crop in China and other East Asian countries. The subtropical monsoon climate zone has abundant precipitation, numerous rivers, and a well-developed aquaculture industry. The Yangtze River Delta, Pearl River Delta and other places have developed into export-oriented agricultural product processing industry bases.
