May 5th is a long summer.

When it comes to long summer, people's first feeling is that the weather is going to get hot.

In fact, it has been hot for a long time. After a period of sharp cooling, the weather in the whole country has basically warmed up. The temperature in some areas has risen above 30 degrees Celsius, which is obviously more "long summer" than "long summer". People can also see them wearing short sleeves and shorts in the street.

However, with the arrival of the long summer, the weather is not getting hotter and hotter, but it has ushered in a big cooling.

What happened?

1, the big cooling is coming again?

Yes, just as people were immersed in the warmer weather, the big temperature drop came again.

According to the forecast of China Climate Center, a new wave of cold air will appear in northern China on May 5th.

And on May 6, it quickly covered Northeast China and North China.

With the appearance of this cold air, the temperature in these areas will also drop rapidly, generally reaching about 4~ 10℃, but the cooling range in Jilin, central and eastern Inner Mongolia and northern Hebei will increase, reaching 12- 14℃, and the local drop is even above 14℃.

However, this wave of cold air is mainly concentrated in the northern region, and there are different degrees of cooling weather in northwest, Inner Mongolia, northeast, north China and Huanghuai.

But then, with the arrival of another wave of cold air, it directly affected the southern region, and it was more violent than the last wave, which means that the cooling rate may be even greater.

2, in addition to cooling, there are strong winds, dust and rain and snow.

According to the Meteorological Observatory, this round of cold air did not come alone, but in groups. There is no wind, sand, rain or snow left.

Some areas such as Liaoning and Jilin will usher in dusty weather, and then it will spread to Inner Mongolia, Gansu and Ningxia.

Rain and snow are mainly concentrated in some areas such as northern Heilongjiang and northeastern Inner Mongolia, which may have another impact on the corn market.

At present, it is the critical period of spring sowing. Many farmers are counting on this precipitation for spring sowing, but we should pay attention to the weather changes in wheat producing areas.

3, during the wheat harvest, beware of heavy rain.

In addition to the big cooling, what needs to be vigilant is heavy rain.

According to the forecast, the rainstorm is mainly concentrated in the southern region. For example, since May 6th, there have been heavy rains and local rainstorms in parts of eastern Guizhou, southwestern Hunan, western Guangxi and northwestern Guangxi.

With the development of rainstorm, the rainfall will spread to North China and Huanghuai area by 9-10, but the strongest rainfall is still concentrated in the south.

However, it is necessary to be vigilant that North China and Huanghuai areas will immediately enter the wheat harvest season. Although the forecast shows that it is mainly moderate to moderate rain, the weather changes are uncertain, and the specific situation depends on the subsequent development.

So you need to pay special attention.
