What's the climate like in Shanghai?

Hello, I'm glad to answer your question.

1. Shanghai has a subtropical maritime monsoon climate. The main climatic characteristics are: warm in spring, hot in summer, cool in autumn and cold in winter, moderate annual rainfall and relatively even seasonal distribution. Generally speaking, the climate is mild and humid, with four distinct seasons.

The highest temperature in Shanghai is in July and August. In recent years, the summer in Shanghai is getting hotter and hotter, and the number of high temperature days exceeding 35℃ is about 10 days. 1Late October to early February (usually during the Spring Festival) is the coldest time in winter. Although there are few days of sudden cold (usually lasting for three days), the wet cold in the south of the Yangtze River is too much for northern Renye Fang, and the biting north wind often blows. Don't wear some heavy warm clothes, gloves, scarves and hats should be fully armed. There are not many days of snow, sometimes it doesn't snow all the year round. March to May is the best tourist season in full bloom in spring. What needs special reminder is that the rainy season is from mid-June to early July, both sunny and rainy. The rainfall of more than 20 days accounts for about 1/4 of the whole year, so it is not suitable to travel during this period. From the end of August to the middle of September, typhoons are frequent, and there are often downpours. You must take a sun umbrella to Shanghai during these two periods. Fortunately, the climate is hot at this time, and sunny days can also be used as sun protection.

The time of sunrise and sunset in Shanghai is 6: 49 in winter solstice, sunset 16: 57, sunrise 19: 0 1 in summer solstice.

With the global warming, Shanghai is not immune. On the occasion of the "World Meteorological Day", meteorologists said that Shanghai has passed the 16 consecutive warm winter since 1988, and the trend of climate warming is intensifying.

Tomorrow is World Meteorological Day. Around the theme of this year's Meteorological Day, "Our Future Climate", the Municipal Meteorological Bureau held a popular science report meeting yesterday. Experts point out that even if all carbon dioxide emitted into the atmosphere is reduced from now on, climate change caused by human activities will last for centuries. In the next 50 years to 100, the global and China climate will continue to develop in a "warm" direction, and the warming rate will be accelerated.

This winter, the temperature in Shencheng dropped to below zero 17 days, more than last year 10 days. Many citizens speculate that warm winter will bid farewell to Shencheng. However, according to Xu Jialiang, an expert from Shanghai Climate Center, whether winter is warm or not mainly depends on whether the average temperature in the three months of 65438+February, 65438+ 10 and February in that year exceeds the average temperature in the past 30 years, and the average temperature in the past 30 years will be updated every 10. The average winter temperature in Shanghai this year is 6.6 degrees Celsius, which is lower than 7.9 degrees Celsius last winter, but still higher than the average winter temperature in 197 1 ~ 2000/.1Celsius. Are the rising temperature, rainy season and cold winter related to global warming? It was learned from the seminar on track construction of regional climate change in Shanghai held on February 12 that the expert group of Shanghai Regional Meteorological Center is conducting in-depth research on climate change in East China, hoping to solve various "fogs" such as extreme weather events and climate change as soon as possible.

Dr. Chen Baode, an expert from China Meteorological Bureau, pointed out that the trend of climate warming in East China is obvious. Meiyu is a unique climate phenomenon in the south of the Yangtze River in early summer. In recent years, it lasts for a short time, and high temperature days above 36 degrees Celsius frequently appear. In the future, the definition of "Meiyu" may be re-formulated.

In the study of regional change, typhoon is also a key point. Dr. Lei Xiaotu, director of the Climate Center of the Municipal Meteorological Bureau, said that the intensity of typhoons in the western Pacific that affect China is getting stronger and stronger. Although there were no typhoons that landed directly in East China in the past, it does not mean that there will be no typhoons in the future. Experts are studying an assessment report on climate change in eastern China in the next 20 to 30 years.

3. Shanghai is located in the eastern part of the Yangtze River Delta where rivers and seas meet, in the north subtropical region where the East Asian monsoon prevails, and belongs to the north subtropical monsoon climate. Affected by the advance and retreat of the winter and summer monsoon, the northwest wind prevailed in Shanghai from June165438+1October to February of the following year, with a cold and dry climate, and the southeast wind prevailed from April to August in summer, which was warm, hot and humid. However, under the direct control of the subtropical high in the northwest Pacific, southwest winds sometimes blow in July and August, and the weather is hot and dry. March and early September to 10 are the transition seasons of monsoon transition, with northeast wind and east wind as the main winds, with more low temperature and rainy weather.

The main climatic characteristics of Shanghai: Leng Xia is hot in winter, with four distinct seasons, but there are often cold currents in winter; In the same season of rain and heat, there is abundant precipitation, but the variability is large; Light and temperature are coordinated, and there are many sunshine, but it varies from year to year. According to Shanghai meteorological data statistics (1873 ~1994); The annual average temperature is 15.5℃, the coldest in June is 1, and the average temperature is 3.4℃. It is the hottest in July, with an average temperature of 27.5℃. The frost at the end of April 1,1the frost at the beginning of October 1 16, with an average frost-free period of 228 days. The active accumulated temperature above 10℃ is 4934℃/ day, which is second only to Sichuan Basin and the south of Hangzhou, Anqing, Wuhan and Yichang. Average annual precipitation 1 149.8 mm, precipitation days 13 1 day. The average monthly rainfall from April to September is above 100 mm, and the total rainfall in these six months accounts for about 70% of the total rainfall in the whole year. June and September are two obviously rainy months.

The monthly rainfall in June reached more than 150 mm, which was caused by plum rain and autumn rain (including tropical cyclones) respectively. The sunshine in each month is above 150 hours, and there are more sunshine in July and August, reaching 25 1 and 260 hours respectively. In June 5438+10, the climate was cool, sunny and rainy, and the temperature difference between day and night was large.

Generally speaking, the climate in Shanghai has three characteristics.

First, Leng Xia is hot in winter with four distinct seasons, but there are often cold currents.

Second, in the same season of rain and heat, there is abundant precipitation, but the change range is large.

Third, the light and heat are coordinated, and there is more sunshine, but it is changeable all year round.
