Weather conditions on 5 May 20 17

Since 2020, changeable weather has been a hot topic? Topic? In May, many people also saw the high temperature and cold air, which made us wonder how the earth's climate developed. Indeed, in a short time, this may be equivalent to an abnormal climate phenomenon, which was relatively rare in the past.

On May 5th, we ushered in the long summer, the first solar term in summer, but the great changes in the weather still exist. According to the data of the Central Meteorological Observatory, a new cold air appeared on the 5th, in which the temperature in northwest and other places will drop by 4 ~ 6℃ successively, and the local temperature will be above 8℃. What's going on here? ? Long summer? Suddenly it's getting cold? Of course, cold air activity has increased recently.

At the beginning, we also saw that many places in the north broke through the high temperature above 40 degrees, and now it has also declined under the influence of cold air. Judging from the development of cold high pressure, some areas such as Northeast China, North China and East China are currently in the cooling range, and Jiangxi, Guizhou and other places still have low pressure control. Combined with the problem of rainfall, these areas may appear? Steamer? Speaking of rain, let's look at the problem of rain. On May 4th, China issued a rainstorm warning, and on May 5th, it continued to issue a rainstorm warning, mainly in the central and eastern parts of the south of the Yangtze River, with heavy rainfall, including heavy rain in central Zhejiang.

From the forecast chart, we see two? Rainstorm point? In Zhejiang, the central rainfall is 1.20 mm, so it is very strong. There is a 70 mm rainstorm in Jiangxi, which is the main rainfall interval. It can be seen from the 24-hour rainfall forecast that the current rainfall is mainly concentrated in Fujian, Zhejiang, Jiangxi and other places, with moderate to heavy rain.

Here we are on the 6th. The overall rainfall will expand, and the northern region will usher in new rainfall, especially in Inner Mongolia and Gansu. On the 7th, there will be large-scale rainfall in North China, Huanghuai and other places, so the rain will continue to expand, with heavy rains in eastern Hubei, northeastern Sichuan Basin and northern Chongqing. After this period of time, the rainfall will continue to develop in the direction of East China.

According to the forecast, the rain will last for four days, that is, there will be a large-scale rain in China from 6th to 9th. It is true that in summer, the rain will increase obviously, so it is necessary to take precautions against rain. When the rain continues to increase, it may cause floods. The National Climate Center also said that this year's flood control problem may be more severe, so this is an early warning.

Generally speaking, the weather in summer is complex and changeable, which is normal, but there may be more extreme weather phenomena this year. The World Meteorological Organization also released a description of the climate trend in 2020, that is, extreme high temperature weather (abnormal high temperature) may occur in many places around the world this year, so high temperature in 2020 may be a hot topic.

At the same time, we should know that the long summer is the beginning of our summer in the seasonal sense, which shows that the weather in the north may also rise gradually, while there will be more rain in the south, and the storms in the marine areas may also develop slowly. Of course, for many people, the Pacific Northwest is still relatively quiet. Although many typhoon embryos were formed, no typhoon was formed in the end, so many people think there are fewer typhoons this year. However, this statement is contrary to the forecast of the Climate Center. According to the Climate Center, this year's typhoons are slightly more intense, and there may be more typhoons landing, so we should not take them lightly. Today's calm ocean area does not mean that there is no response. In fact, there are still many tropical disturbances developing.

So a typhoon will form sooner or later. We saw a typhoon at 1 in 20 19, which is later this year. Later, when the typhoon is very active, may it last? Typhoon? Therefore, everyone should pay attention to the development of typhoons in real time, and I will follow up the development and changes.
