Winter limited return in some areas? Sandstorm, snowstorm, thunder and cold are coming, please remember to put on more clothes in time!

This week, the weather across the country has been complex and changeable.

Cold air, sandstorms, rain, snow, severe convection and other weather conditions are coming in groups.

Strong cold air is about to end the advanced warm weather

15 provinces experience seasonal cooling

Recently, the temperature in most parts of central and eastern my country has been escalating.

High temperatures hit Sichuan, Zhejiang and other places

Temperatures in many places broke historical records, as if it were early summer

But a strong cold front is about to interrupt this early warm spell

Affected by strong cold air

The fierce reversal of cold and warm officially begins

More than 25 provinces and cities in my country will experience a temperature "roller coaster"

The temperature in many places may drop by more than 20℃

Wang Weiyue, a meteorological analyst at China Weather Network, said that the main characteristics of this cold front are the sharp drop in temperature and wide impact area. It is expected that in the next five days, the daily average temperature in most parts of Northwest China, North China, Northeast China, Huanghuai, Jianghan, Jianghuai, and Jiangnan will drop by 6-10℃, and in some areas by 12-14℃, and in some places by more than 16℃.

The north may experience the tenth sandstorm this year

Heavy rainfall in southern China accompanied by severe convection

Strong cold air not only blocks the progress of summer

There will be sandstorms again

According to the Central Meteorological Observatory at 18:00 on April 19

Blue sandstorm warning issued

Expected to be from 20:00 on April 19 to 20:00 on April 20

Central and western Inner Mongolia, southern and eastern Xinjiang,

Most of Gansu, Ningxia, Shanxi,

There will be blowing sand or dust in parts of western Hebei, Beijing and other places

Southern Xinjiang, Eastern Gansu,

There are sandstorms in parts of central Ningxia, northern Shaanxi and other places

The frequency of sandstorms in China this year is the highest in the same period in the past 10 years. According to the data of the China Meteorological Disaster Yearbook (2020), the average number of sandstorms from March to April in the past 20 years is 7.8 times. This April has not yet ended, and the number has exceeded the average.

From the 20th to the 23rd, the central and eastern parts of China will see a round of large-scale precipitation , with the precipitation reaching its peak from the 21st to the 22nd, covering the central and western parts of North China and South China. As the temperature drops, snow may fall in the eastern part of the Northwest and parts of North China; after the cold air moves southward and combines with the warm and humid air currents, there will be heavy to torrential rain or even heavy rain in parts of the south of the Yangtze River. It is also necessary to guard against short-term heavy rainfall, thunderstorms, hail and other strong convective weather.

As the temperature drops

20-23: Qinghai, Gansu, Ningxia, northern Shaanxi

Central and northern Shanxi, northern Hebei, etc.

Snow is also possible in high altitude areas

After the temperature drops, although the temperature is no longer as cold as in winter,

But the fluctuating temperature

It is easy to catch a cold

Please remember to put on more clothes in time and close the windows to prevent sand

At the same time, we should prevent secondary disasters that may be caused by precipitation.

Understanding the characteristics of severe convective weather and mastering defense methods can save lives at critical moments.
