Causes of "Late Spring" in Jiangsu and Zhejiang Coastal Areas

Because the climate in coastal areas is generally "maritime climate".

Compared with continental climate, the main feature of maritime climate is that not only the annual and daily variation of temperature is small, but also the extreme temperature appears later than that in continental climate area. The seasonal distribution of precipitation is relatively uniform, with more precipitation days and less intensity. There are many clouds and high humidity. Judging from the annual temperature change, spring is colder than autumn, which is an obvious sign of maritime climate. The warmest month appears in August and even lasts until September. Leng Yue is the most in February, and the high latitudes are postponed to March. People usually regard the coastal areas of northwest Europe as a typical maritime climate on the mainland.

Under the condition of maritime climate, the climate is humid all the year round, and the average annual precipitation is more than that of continental climate. And the seasonal distribution is more uniform. Precipitation is relatively stable, with little change from year to year. The four seasons are wet, cloudy and cloudy, and the weather is gloomy. It is rare for sunny days to have sunshine.
