Why is it so cold this summer?

We all know that there will be sunny weather after the May Day holiday every year, but this year's weather is very abnormal. The northern region will wear long pants in May, so why is it so cold this summer? Let's take a look at the specific details.

Why is it so cold this summer? On May 5th this year (Thursday), China officially entered the long summer, but after the long summer, many places in China have not recovered. On the contrary, there is a lot of cold air, which leads to the rare coolness in May. The highest temperature in some places such as North China, Shandong and Henan even broke the lowest record in the same period in history, while the highest temperature in Guizhou, northern Hunan, northwestern Jiangxi and Zhejiang was generally less than 15℃. So it also makes everyone feel that this May this year is colder than before. I remember last May 1 day, I could put a mat on the bed, but this year's mat has not been taken out, which is really common. In this regard, the National Meteorological Administration has given the following reasons for climate anomalies:

1. One of the reasons why it was so cold this summer: the impact of La Nina.

In the summer after independence, there was a rare May cold in many areas. I should have put on short sleeves, but I didn't expect people to be shivering with cold, so I had to dig out the autumn clothes and trousers and wear them on my body. The key factor leading to the sudden drop of temperature is La Nina event. In addition, since June last year 165438+ 10, China has experienced cliff-like cooling due to the La Ni? a event, and now the cold in May is also affected to some extent by the La Ni? a event.

It is too cold this summer. The second reason is the frequent cold air activity.

Although it has entered May, cold air frequently affects our country, and the temperature fluctuates greatly. It doesn't necessarily enter summer in May every year, and the temperature will be low in May every year. And I happened to meet it this year, so it makes people feel a little abnormal. In fact, the weather is changeable, and no one can guarantee that it will be hot in May. Coupled with global warming in recent years, abnormal weather is normal. For example, it snows in some parts of the north in April, and this phenomenon will only increase in the future.
