In a year, with the reverse transformation of winter and summer monsoon, the weather system, control air mass and weather conditions will change obviously seasonally, forming the climate characteristics of rainy spring, humid summer, fresh air in autumn and dry and cold winter. Due to the complex landform and uneven terrain, the geographical distribution of light, heat and water in Hangzhou is uneven, and the local microclimate resources are rich. However, due to the instability of monsoon advance and retreat time and duration, there are often anomalies of cold, hot, dry and wet, which lead to disastrous weather.
