Foreword: "The wind is warm and the peach blossoms are fragrant, the rain is sunny and the grass is green", tomorrow on April 19~23, there will be two waves of heavy rainfall lined up, and the heavy rain and heavy rain are distributed in which areas? Let's find out.
Today is April 18th, the tenth day of the third month of the lunar calendar, at this time, the willow saffron, the greenery is getting stronger, the weather is gradually getting hotter and warmer, the rain is getting stronger and stronger, and the breath of spring in the air has been dispersed.
Cold air fluctuations and temperature changes in the coming days:
With the continuous strengthening of cold and warm air activities in the past two days, many places in the south have once again ushered in a large range of short-term heavy precipitation, thunderstorms, gales and hail and other convective weather, not only Jiangxi and Hunan have short-term precipitation and thunderstorms, Zhejiang, Fujian, Hubei, Sichuan, Chongqing, Guizhou, southern Henan and other places, there are strong heavy storms and rain weather.
According to the latest weather forecast, the cold air activity from the north is still relatively active in the next few days, coupled with the rainy weather in most parts of the south, the temperature in many places in the central and eastern parts of the country has declined compared with the same period in previous years, and the maximum local cooling range is more than 4~8 °C, but the weather in most of the rest of the mainland continues to accelerate the rebound.
In this way, it is now late spring, and the cooling weather brought by the cold air is getting weaker and weaker, and most of the cooling areas are mainly affected by the rainy weather, and the state of cold air cooling has been difficult to achieve.
In the past two days, many cities in the north are in the warm sunny weather, and the temperature is particularly obvious, among which the temperature in many places in North China has exceeded the 30 °C mark, but with the arrival of rainy weather, the temperature in some areas will fluctuate and decline again.
However, under the influence of rainy weather, the temperature fluctuation range in the middle and lower reaches of the Yangtze River, the southern part of the Yangtze River and many places in southern China continued to increase, which shows that the impact of continuous rain and insufficient sunshine on the daytime temperature is still relatively obvious.
Tomorrow, April 19~23, where will the heavy rain and heavy rain fall?
After entering tomorrow's April 19~23, with the acceleration of the eastward movement of the upper-air trough, as well as the combined effect of the accumulation of rain clouds and warm and humid airflow, the southern region will once again usher in the weather process of heavy rainfall and strong convection.
Moreover, there are still strong precipitation and strong convective weather in Jiangnan, South China, Guizhou and other places, especially in Guangdong, Guangxi and other places, the rainfall is relatively large, and the rainfall duration is relatively long.
When it came to the 19th ~ 20th, the heavy rainfall was mainly concentrated in the central and eastern parts of Jiangnan and the northern part of South China, southwest Zhejiang, southern Anhui, northwestern Guangxi, northwest Fujian, eastern and northern Guangxi, eastern and southern Hunan, central and northern Jiangxi, central and eastern Guizhou, and other places, with heavy to heavy rain or heavy rain weather.
In addition, the precipitation in North China and Northwest China has weakened, and the scope of rainy weather has continued to shrink, with light to moderate rain and locally heavy rain in parts of western North China and eastern Northwest China.
Immediately following the 21~23rd, under the superimposed influence of continuous rainfall, heavy rainfall and convective weather, most of Jiangnan, most of South China, Sichuan Basin, eastern Guizhou and other places once again ushered in a wave of heavy rainfall process, of which the eastern and southern parts of Jiangnan, the central and eastern parts of South China and other places have heavy to heavy rain, and there are local heavy rainstorms.
It can be seen from the above that in the next few days, there will still be continuous rainy weather in the central and eastern regions, Jiangnan and South China, and it will be disturbed by strong convective weather locally, but the central part of Yunnan is still in the weather condition of scarce rain.
With the gradual deepening of the late spring, even if the cold air activity is frequent, but the intensity of the cold air is getting weaker and weaker, the impact on the spring weather of the rising temperature is getting smaller and smaller, and the temperature in many areas in the central and eastern parts of the country and the north has broken through the 20 °C mark.
