At the turn of spring and summer every year, it means that the weather begins to get warmer, but it also means that it begins to rain in summer, that is, it enters the annual flood season.

Every year during the flood season, we will collect them specially. On the one hand, it will affect people's travel, and even floods caused by excessive rainfall in some areas in previous years have caused serious threats and losses to people and property.

On the other hand, this time is often the key time for crop growth. For example, May and June are the seasons for wheat harvest. During the wheat harvest last year, several main producing areas suffered from heavy rainfall, which led to the differentiation of wheat quality, and many wheat mildewed and their quality declined.

This year has once again entered the flood season (May to September), so what will happen to this year's flood season?

1, this year's flood season pays equal attention to drought and flood, and it is more likely to rain in the north.

According to the forecast of the National Climate Center, the climate situation in flood season in China is generally average this year, mainly showing the trend of paying equal attention to drought and flood. Regional and staged droughts and floods are more obvious, and extreme weather is relatively increasing. Floods are more likely to occur in the north and south, while droughts are more likely to occur in the central region.

China has a vast territory, and the geographical climate and environment in different regions are quite different, so the temporal and spatial distribution of rainfall is also very uneven, so the frequent droughts and floods caused by it are normal from ancient times to the present.

From the basin, the Nenjiang River, Songhua River, Heilongjiang River and Haihe River basin in the north, the main stream of the middle reaches of the Yellow River and its tributaries, such as Jinghe River and Fenhe River, may have large basin floods; However, regional floods may occur in the upper reaches of the Yangtze River in the south, the Xijiang River in the Pearl River basin and the southeast coastal rivers. Regional drought may occur in the middle reaches of the Yangtze River and the lower reaches of the Han River.

2. Some provinces and regions may usher in the strongest precipitation since the flood season.

The above is a feature of the whole flood season, but recently, due to the influence of airflow, there will be heavy rain to heavy rain in southern China, and even the strongest rainfall may occur in many areas since the flood season.

This round of heavy rainfall in the south is mainly concentrated in southern Jiangnan and southern China.

Geographically, the rainfall in Guangxi, Guangdong, Fujian, southern Hunan and southwestern Jiangxi will become more obvious and become the key rainfall areas.

In particular, there will be heavy rain in most areas of Guangdong and Guangxi, and the daily rainfall of individual stations may reach historical extremes.

In addition, in addition to heavy precipitation, there will be strong convective weather such as thunderstorms or hail in some of the above areas.

3. Cold air is "online", and the northeast and north China are greatly cooled.

In fact, since May Day, the cold air has been extremely active, and the weather in many places in the north has turned cold.

However, this wave of cold air is not over yet, and it will continue to affect Northeast China and North China, and the temperature will drop further. Among them, the temperature drop in most parts of Inner Mongolia, Northeast China and North China is about 4-8 degrees Celsius, and the local temperature can reach 10 degrees Celsius, accompanied by strong winds.

This also means that the temperature in North China and other places will continue to be low in the coming week.

At present, rainfall and low temperature weather have little effect on wheat harvest, but spring ploughing may be affected to some extent. Pay attention to collecting weather changes and making farming plans.
