The law of climate change in Shanghai

The ball is getting warmer, and Shanghai is no exception. 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.
