 Cold wave strong convection double early warning occurs together, the temperature in many parts of the country will fall to the freezing point


Temperature in the north will be cut by the waist in Xining, Taiyuan and other places in two seasons a day

In recent days, most areas of China have been warming, and the front line in spring has been pushed to Beijing, Tianjin and Hebei. On May 25, temperatures in the east of Northwest China, North China, Huanghuai, northeast and other places will rise to near-term highs. Harbin, Changchun, Hohhot, Xining and Xian will all set new highs this year. Among them, Harbin will go up 10 u2103 for the first time this year, and Xining will go up 20 u2103 for the first time.

The cooling range of 18 provinces and cities on the line of all-round cold wave exceeds 10 u2103

However, the temperature will usher in a big turning point. The Central Meteorological Observatory continued to issue the blue warning of cold wave this morning. It is predicted that from 25th to 28th, most of the central and eastern regions will have 4-6 level winds and 7-9 level gusts successively from north to South; the temperature will drop by 6-10 u2103, and the cooling range in some regions can reach more than 12 u2103. On the morning of the 28th, the lowest temperature in North Central Hebei, Beijing and Shanxi will fall to 0 u2103 or below; on the 29th, the lowest temperature in Huanghuai, Jianghuai, Jianghan and Jiangnan will be 4-9 u2103.

According to the China Weather Network meteorological analyst, 26, with the cold air moving eastward and southward, the eastern part of the northwest, North China, and most of the Northeast will have strong cooling, such as the central and Northern Shanxi, Northern Shaanxi, central and Eastern Inner Mongolia, northern Hebei, western Liaoning and other places may fall by more than 10 u2103.

In the city, Xining and Taiyuan can cool down to 15 u2103 in a single day, and Hohhot, Changchun, Yinchuan, Shenyang and Beijing will all reach or exceed 10 u2103. The temperature will be cut off. Due to the high temperature in the north recently, the sudden drop in temperature will make many places experience two seasons a day.

This cold wave has a wide range of influence, and it is also an all-round cold wave with rain, snow and sand. In addition to cooling, cold air will also bring 4-6 wind, gust 7-9. From the 25th to the 26th, there will be dust weather in eastern Xinjiang and southern Xinjiang basin, western Inner Mongolia, central and western Gansu, Ningxia and other places, and there will be dust storms in local areas, so we need to pay attention to prevention.

In some southern areas, the temperature has dropped for two consecutive days, and the cumulative temperature drop in Nanchang, Hangzhou exceeds 15 u2103

On the 27th, most of the South will also join the ranks of cooling. The daily cooling range is not as severe as that of the north, around 6-8 u2103, but the cumulative cooling range is large. Within two or three days from the 27th, some areas will also exceed 10 u2103. In cities, the cumulative decline of the highest temperature in Hangzhou can reach 17 u2103, in Nanchang 16 u2103, in Changsha 15 u2103, in Guiyang 14 u2103, and in Shanghai 13 u2103, with the highest temperature falling to more than 10 u2103. On the 29th, the lowest temperature in Jianghuai, Jianghan and Jiangnan was only 4-9 u2103.

Meteorological analysts warned that in general, under the influence of this strong cold air, the temperature in the Middle East will turn from the previous high to low. This cooling process lasts for a short time. In fact, most places fail to meet the standard of cold in late spring in a strict sense. However, the temperature fluctuates greatly, and the change between cold and warm is intense. Please dont rush to collect your thick clothes first, pay attention to keeping warm, and be careful not to catch cold.

There is rainstorm or heavy rain in Inner Mongolia or in southern China

Cold air will bring rain and snow to many places in the north. According to Zhang Juans analysis, the rain and snow in the North mainly occurred from the night of the 25th to the 26th. The central area of Inner Mongolia is dominated by snowfall, and there may be sleet in the central and northern parts of Shanxi, Northwest Hebei, western Beijing and northern mountain areas. At the same time, due to the high temperature and the accumulation of atmospheric energy in the north in the near future, it is possible to snow and thunder while excited by cold air.

It is estimated that from March 25 to 27, there will be moderate to heavy rain in the east of Southwest China, Jianghan, south of Huanghuai, Jianghuai, Jiangnan and most of South China, and there will be rainstorm or heavy rain in the local area, accompanied by thunderstorm, gale, hail and other strong convective weather. The accumulated rainfall in the above areas is 30-80mm, and the local rainfall can reach 100-160mm. The heavy rainfall mainly occurs from the 26th to the 27th. The precipitation brought by the cold air to the north is conducive to the increase of soil moisture and the growth of winter wheat jointing. However, the greenhouse reinforcement, cold prevention and heat preservation work should be done well in the protected agriculture and pastoral areas, and effective measures should be taken to avoid or reduce the adverse effects of cooling on the fruit trees entering the flowering period. In the area of over wet soil in the south of China, it is necessary to clear the ditch and drain the water and disperse the soil moisture in time, and to prevent the adverse effects of heavy rainfall and convective weather on the spring sowing and the flowering and podding of rape.
