The environment of Jianye District

Jianye District has a humid northern subtropical climate. Under the control of westerly circulation, the monsoon is significant and the four seasons are distinct. Winter is deeply affected by the Eurasian continental air mass and is controlled by the Siberian High (or Mongolian High). There are mostly northerly winds and the weather is sunny, cold and dry. In summer, the temperature of Eurasia rises sharply and becomes a low-pressure area. The Siberian high pressure center declines to the west of Lake Baikal. The high-altitude westerly belt moves northward. The Pacific subtropical high pressure strengthens. Warm and moist air blows from the ocean to the continent. Under its control, the territory There are strong southeasterly winds, hot weather and abundant rainfall. Spring and autumn are the seasons in the transition process between winter and summer. In spring, as the continent warms from cold, the Siberian cold high attenuates and splits, and part of the center moves to the Yellow Sea, resulting in more northeasterly and easterly winds in the region. In autumn, the continental air cools and sinks, the Pacific subtropical high pressure retreats to the southeast, the Siberian high pressure begins to strengthen, and the territory is gradually controlled by the northern cold air mass, forming dry and cool weather.
