Similarities and differences of climate characteristics between Beijing and Jinhua

Beijing's climate is a typical semi-humid continental monsoon climate in the north temperate zone, with high temperature and rainy summer, cold and dry winter and short spring and autumn. The frost-free period of the whole year is 180 ~ 200 days, which is shorter in the western mountainous area. In 2007, the average rainfall was 483.9 mm, which is one of the most rainy areas in North China. The seasonal distribution of precipitation is very uneven. 80% of the annual precipitation is concentrated in June, July and August in summer, and there are heavy rains in July and August.

Jinhua has a subtropical monsoon climate. The general characteristics are four distinct seasons, moderate annual temperature, abundant heat and rainfall, and obvious dry and wet seasons. In spring, the temperature rises rapidly, but the temperature changes irregularly. Rain is concentrated in late spring and early summer, with hail and strong winds. Summer is long and hot, rain and heat rise synchronously, often accompanied by drought; Autumn is cool, the air is humid and the time is short; Winter is sunny, cold and dry, and the atmospheric stratification is stable. The overall light and heat conditions are superior throughout the year, but the spatial and temporal distribution is uneven. There are various microclimates in the basin with certain vertical differences. Due to the instability of monsoon climate, severe weather such as drought and flood occurs frequently.
