What's the climate like in Zhejiang? How does this climate affect people?

The complex terrain in Zhejiang province leads to different tourist seasons in different parts of Zhejiang.

Generally speaking, spring and autumn are the most suitable seasons to travel to Zhejiang, especially Qiandao Lake in spring makes people wonder if they are in heaven, and of course tourists are indispensable at this time. In summer, western Zhejiang is much cooler than other places in Zhejiang, so western Zhejiang should be the first choice for travel. In winter, most areas in Zhejiang are mainly sunny, cold and dry, and there is little rain. So the biggest advantage of traveling to Zhejiang this season is that it is convenient to travel. Because it is cold and there are few tourists, it provides convenience for photographers.

The climate in Zhejiang is characterized by obvious monsoon, distinct seasons, moderate annual temperature, abundant sunshine, abundant rainfall, moist air, synchronous seasonal changes of rain and heat, diverse allocation of climate resources and numerous meteorological disasters. The annual average temperature in Zhejiang is 15 ~ 18℃, the extreme maximum temperature is 33 ~ 43℃, and the extreme minimum temperature is -2.2 ~- 17.4℃. The average annual rainfall in the province is 980 ~ 2000mm, and the average annual sunshine hours are1710 ~ 2100h. In spring, the East Asian monsoon is in the alternate season between the winter wind direction and the summer monsoon. The north-south airflow frequently meets, and the low pressure and frontal activity intensify. The climate in Zhejiang in spring is characterized by cold and rainy weather, frequent coastal and offshore winds, more rain in the whole province and uncertain weather. As the saying goes, "three faces change in spring." The average temperature in spring in Zhejiang is 13 ~ 18℃, and the temperature distribution is decreasing from inland areas to coastal and island areas. The precipitation in the whole province is 320 ~ 700 mm, and the distribution of precipitation gradually decreases from southwest to northeast coastal areas; The rainy days in the whole province are 4 1 ~ 62 days. The main meteorological disasters in spring are rainstorm, hail, strong wind and low temperature in late spring.

In summer, with the establishment of the summer monsoon circulation system, the southeast wind prevails in Zhejiang, and the subtropical high activity in the northwest Pacific has an important influence on the weather in Zhejiang, while the cold air from the north to the south still has a certain influence on the weather in Zhejiang. In the early summer, all parts of Zhejiang have entered the flood season one after another, commonly known as the "Meiyu" season, and the probability of heavy rain and heavy rain increases, which is easy to cause floods; In midsummer, affected by subtropical high, Zhejiang is prone to sunny, hot and rainy weather, leading to drought; Summer is the period with the greatest probability that tropical storms will affect Zhejiang. The summer climate in Zhejiang is characterized by high temperature, abundant precipitation, strong illumination, humid air and frequent meteorological disasters. The average summer temperature in the whole province is 24 ~ 28℃, and the temperature distribution is decreasing from the central area to the surrounding areas. The precipitation is 290 ~ 750 mm in various places, with more precipitation in eastern mountainous areas, such as Tiantai Mountain, Yandang Mountain and Siming Mountain, and less precipitation in islands and central areas. It rains for 32 to 55 days in all parts of the province. The main meteorological disasters in summer are typhoon, rainstorm, drought, high temperature, thunderstorm, strong wind and tornado. In autumn, the summer monsoon gradually weakens and transitions to the winter monsoon. Cyclone activity is frequent, frontal precipitation is more, and temperature changes greatly. Characteristics of autumn climate in Zhejiang: in early autumn, Zhejiang is prone to intermittent rainy weather, commonly known as "autumn Lasha"; Mid-autumn, controlled by the high-pressure weather system, Zhejiang is prone to high-sky, light-cloud and sunny autumn weather, which is called "Koharu in October"; In late autumn, the influence of cold air in the north began to increase, and the conversion process between cold and warm weather and sunny and rainy weather was frequent, and the temperature fluctuated greatly. The average autumn temperature in the whole province is 16 ~ 2 1℃, with high temperatures in the southeast coastal and central areas and low temperatures in the northwest mountainous areas. The precipitation is 2 10 ~ 430mm, with more precipitation in the central and southern coastal mountainous areas and less precipitation in the northeast, but its interannual variation is great. It rains all over the province for 28 ~ 42 days. The main meteorological disasters in autumn are typhoon, rainstorm, low temperature, rainy weather and fog.

In winter, the strength of winter monsoon in East Asia mainly depends on the activity of Mongolian cold high pressure, while the weather in Zhejiang is affected by the cold air mass in the north (that is, winter monsoon), and there are relatively few types of weather processes. The winter climate in Zhejiang is characterized by abundant sunshine, cold and little rain, and dry air. The average winter temperature in the whole province is 3 ~ 9℃, and the temperature distribution is decreasing from south to north and from east to west. Precipitation 140 ~ 250 mm, except for the northeast islands, there is little difference in other places; The rainy days in all parts of the province are 28 ~ 4 1 day. The main meteorological disasters in winter are cold wave, freezing injury, strong wind, heavy snow and fog.
