China Weather Network News In the first ten days of March, after many places in my country experienced a collective recovery, in the middle of March, cold air became more frequent.

Today (March 11), there will be a cold air moving eastward and southward, the temperature in the Northeast and North China will drop sharply, and the precipitation will also show an increasing trend. The rain will be accompanied by thunder and lightning. This may be the largest thunder and lightning since the beginning of spring. During the event, thunder will be heard in over 10 provinces, autonomous regions and municipalities.

The central and eastern regions will welcome two rounds of precipitation, which will help ease the meteorological drought in the Huanghuai region

  The Central Meteorological Observatory predicts that in mid-March, cold air activities will become more frequent. From the 11th to the 13th, and from the 16th to the 17th, there will be two large-scale precipitation processes in the central and eastern regions.

  From the 11th to the 13th, there will be a large-scale rain and snow weather process in the central and eastern regions and northern Xinjiang. There will be light rain in the eastern Northwest region, central and southern North China, Huanghuai, Jianghuai, Jianghan, eastern Southwest China, and Jiangnan. Among them, southern Shaanxi will have light rain. , In parts of southern Shanxi, southern Hebei, northern and eastern Henan, Shandong, northern Jiangsu, northern Anhui, and eastern Hubei, there are moderate to heavy rains accompanied by thunder and lightning, and there are rains in northern North China, most of Northeast China, and northern Xinjiang. Mixed snow or light snow, including moderate to heavy snow and local blizzards in parts of northeastern Inner Mongolia, northern Hebei, Xinjiang Altay, and the western part of the Tianshan Mountains.

  According to Shi Yan, a meteorological analyst at China Weather Network, this precipitation process will help ease the meteorological drought in the Huanghuai region.

Since February, precipitation in Henan, Shandong, and northern Jiangsu and Anhui has continued to be low. Monitoring shows that Puyang, Anyang, Kaifeng, Xinxiang in Henan, Tai'an, Dezhou, Liaocheng in Shandong, Handan and Xingtai in Hebei, and Taiyuan in Shanxi, from February 1 to March No precipitation continued on the 10th, which was tied for the least in the same period, resulting in moderate to severe meteorological droughts in the above-mentioned areas, and local extreme droughts.

It is expected that from the evening of the 11th to the morning of the 13th, light to moderate rain will gradually appear in the arid area from the northwest to the southeast, and the meteorological drought in this area will be significantly alleviated.

  During this process, there were moderate to heavy snowfalls and local blizzards in parts of northern Hebei, northeastern Inner Mongolia, eastern Jilin, Xinjiang Altay, and the western part of the Tianshan Mountains. Shi Yan reminded the above-mentioned areas to guard against the adverse effects of rain and snow on transportation and urban operation. At the same time, seize the opportunity to carry out field management and spring ploughing and spring sowing in winter wheat areas. At present, winter wheat in North China, Huanghuai, Gansu, Shaanxi and other places is in the stage of turning green. Root development, greening, and tiller growth; this precipitation process is also conducive to the sowing and emergence of spring wheat in Gansu, Shaanxi and other places.

The largest lightning strike since the beginning of spring, more than 10 provinces, autonomous regions and municipalities will hear thunder

  Rain is accompanied by thunder and lightning. Thunder may be heard when it rains in Sichuan, Chongqing, Guizhou, Hunan, Hubei, Henan, Anhui, etc. This may be the largest lightning activity since the beginning of spring, and some areas will be the first in this year. thunder.

  From the afternoon of the 11th to the early morning of the 12th, southern Gansu, central and western Shaanxi and other places will be accompanied by thunderstorms and strong winds of magnitude 7 to 8; from the afternoon of the 12th to the night of the 13th, eastern Sichuan, northern Guizhou, Chongqing, Hubei, northern Hunan, and northern Jiangxi. There will be thunderstorms in other places, among which the central and northern parts of Chongqing, eastern Hubei, northern Hunan, and northern Jiangxi will be accompanied by short-term heavy precipitation, with an hourly rainfall of 20 to 30 mm.

  Judging from the perennial thunderstorms, the north is generally early this year, and the south is normal.

In the cities, thunder and lightning are expected to occur in Hefei and Nanjing on the evening of March 12, and thunder and lightning are expected to occur in Nanchang on March 13 and Guiyang on March 14.

Shi Yan added that this large-scale lightning was mainly because the temperature was significantly higher recently before the rainfall, and there was convection energy, so when the cold air first arrived, it was easy to trigger convection.

  Looking forward to the 16th to 17th, there will also be a round of large-scale precipitation in the south. Due to the stronger warm and humid air flow, it is expected that there may be a larger range and more intense strong convective weather. The annual March is the number of thunderstorm days in the south. During the period of double growth, it is also necessary to pay close attention to the latest forecast.

After the abnormally warm central and eastern parts of the country, the temperature dropped sharply, and the cumulative cooling exceeded 10°C

  In the first ten days of March, most of my country's precipitation was less than the same period of the year, the weather was abnormally warm, and the temperature in many places was 4 to 6 degrees Celsius. Northern Xinjiang, northeastern Inner Mongolia, and parts of Henan, Shandong, Hubei, and Anhui The temperature in the area is higher than 6℃.

Among them, the average temperature in some areas of Henan, Shandong, Hubei, Anhui, Jiangsu and other places exceeded the historical extreme value for the same period, and all spent the warmest early March.

  Yesterday, the temperature in North China and most of the south increased, and the highest temperature line of 20°C moved north to the central part of North China and the Hetao area of ​​Inner Mongolia. However, under the influence of cold air today, the temperature in North China, Northeast China and other places will drop significantly. From 4 to 10 °C, local declines in Shanxi, Hebei, Tianjin and other places exceeded 10 °C.

For North China, Northeast China and other places, the maximum temperature tomorrow will drop to the low point of this round.

After cooling down, the temperature in the above-mentioned areas will return to a state close to the same period of the year.

  For areas further south, the cooling will come later, and it will be difficult to change the state of high temperature in the coming week.

Today and tomorrow, the temperature in the south will continue to rise, and many places will reach the high point of this round one after another. The day after tomorrow, the temperature will drop from Shandong to Guangdong. However, the high temperature in the above-mentioned areas will still be maintained, and some areas may still be around the 15th. Refresh the temperature again.

  What is the weather trend in mid-March this year?

It is expected that the temperature in most parts of the country will be significantly higher and the precipitation will be lower in the early stage; in the later stage, the force of cold air will increase, and the temperature in the northern region will turn to be lower.

For the northern region, after the heating stops on March 15, the temperature may be low. China Weather Network reminds friends to add clothes to keep warm to prevent colds.
