Will "extreme high temperature" strike again this summer?

In early March, "hot" has become the key word of recent weather. Southern Reporter learned from the Meteorological Service Center of China Meteorological Bureau that the recent warm and hot weather in China will continue, and the temperature will soar to the recent high point on the 9th and 10, which may break records in many places. Does this mean that this summer will encounter extreme high temperatures as long as last year? Hu Xiao, chief meteorologist of China Weather Network, said, "The current cold and warm weather is not necessarily directly related to the summer temperature." This summer, droughts and floods may be unevenly distributed, and extreme weather will still occur frequently.

The soaring temperature will reach the recent high point, and many places may break records.

The unusually hot weather in the central and eastern parts of China continues. On March 7th, the temperature at 102 weather station broke the record in early March.

On the 9th and 10, the temperature will reach a recent high. The highest temperature of 20℃ will reach western Liaoning, southeastern Inner Mongolia and northern Hebei, and there will be a large range of more than 25℃ from southern North China to southern China, and the highest temperature in some areas can reach 30℃.

The highest temperature in many places will continue to break records. In big cities, the temperatures in Hohhot, Changchun, Shenyang, Jinan and Hefei may all set new local records in early March, and Shijiazhuang, Taiyuan, Wuhan and Nanjing will also experience rare warm weather in the same period.

Before this, warm heat has appeared. Since February, the average temperature in many parts of the country has been higher than normal. From March/KLOC-0 to March 7, the temperature in Northeast China, Northeast Inner Mongolia, Shandong, Henan and other places is also very high.

There may be uneven droughts and floods this summer.

Last summer, a large-scale continuous high-temperature weather process occurred in central and eastern China, lasting 79 days, which is the longest regional high-temperature weather process in China since 196 1 year. The Central Meteorological Observatory issued the red warning of high temperature for the first time since the establishment of the meteorological early warning mechanism in China.

Only at the beginning of March this year, there was a rare high temperature weather in China. Does this mean that there will be a long period of staged extreme high temperature this summer?

"There is no necessary direct relationship between the current cold and warm weather and the temperature in summer." Hu Xiao, chief meteorologist of China Weather Network, said. To put it simply, we can't judge the heat and cold in a longer summer by the abnormal heat and cold wave process now.

According to Hu Xiao, there will be high temperature in areas affected by subtropical high in summer, and the edge of subtropical high is usually full of rain. For such a huge weather system as subtropical high, it is difficult to predict whether it will affect a place for a long time or whether it will oscillate, which is the difficulty of climate prediction.

"But we can also see from the recent abnormal warmth that extreme weather and climate events are increasing in the context of climate warming, and this trend is irreversible. For the most important La Niñ a event that affects our climate, even if there was a' triple La Niñ a' in the past three years, the impact fluctuated greatly. For example, last year, the Yangtze River Basin suffered from extreme high temperature and little rain, but in 2020, the Yangtze River Basin suffered a flood. " Hu Xiao said.

Hu Xiao said that this year is destined to be a year of change. According to the forecast of the World Meteorological Organization, La Nina will end in early spring, and may even turn from neutral to El Niñ o event in May and June. "This summer, we may encounter uneven distribution of droughts and floods, and extreme weather will still occur frequently."
