This winter’s longest-lasting rain and snow weather has the widest impact

According to meteorological experts, the rain and snow weather this time is mainly due to the superimposed influence of the South Branch Trough and the North Branch Trough, which is conducive to the southwestern warm and humid air flow northward, bringing widespread rain and snow weather. The process has the characteristics of wide rain and snow coverage, long duration, large freezing rain range, and extreme accumulated precipitation in some areas.

Rain and snow cover a wide range: This rain and snow process basically covers the entire central and eastern regions. Snowfall mainly occurs in the Huanghuai and areas north of it. Rain turns to sleet or snow in Jianghan, western Jianghuai, western Hunan, eastern Guizhou and other places; Parts of eastern and southern Shaanxi, southern Shanxi, southern Hebei, Henan, Shandong, Hubei, northwestern Hunan, eastern Guizhou, eastern Liaoning, and eastern Jilin have experienced heavy snowfall, localized heavy snowstorms or extremely heavy snowstorms, with cumulative snowfall of 10~20 mm, locally exceeding 30 mm. There were moderate to heavy rains in most areas in the middle and lower reaches of the Yangtze River and south, and heavy rains in some areas; from the 1st to the 4th, there was also a large range of thunder and lightning weather.

Long duration: The rain and snow weather in the central and eastern regions started on January 31 and lasted until February 5, as long as 6 days. After the 6th, there will still be weak rain and snow in the eastern part of Southwest China, southern Jiangnan, and South China, while the weather will turn fine in most areas in northern Jiangnan and north of it.

Freezing rain covers a wide range: From February 1st to 4th, freezing rain occurred in parts of southern Henan, Hubei, northern Anhui, central and northern Hunan, and eastern Guizhou.

Taken together, this round of rain and snow weather in the central and eastern regions has lasted the longest since this winter, with the largest number of provinces experiencing freezing rain. The cumulative snowfall in Henan, Shandong, and Hubei is close to or exceeding the same period in history, which is extreme. However, its duration, low temperature intensity, and freezing range are not as good as the low temperature rain and snow freezing process in the south in early 2008. The scope and intensity of snowfall in the areas south of the Yangtze River are also weaker than that from January 21 to 22, with mainly rainfall.

Temperatures in areas with frequent rain and snowfall in the next 10 days will be slightly lower

It is expected that in the next 10 days, there will be rainy and snowy weather in the Huanghuai and southern regions, with the number of precipitation days reaching 6 to 9 days; the cumulative precipitation is abnormally high, with 120 to 180 mm in some areas in central Jiangnan and northern South China, which is higher than the same period in normal years. 2 to 6 times more.

Compared with the abnormally high amount of rain and snow, the temperature is relatively stable. In the next 10 days, the temperature in the southeastern part of Northwest China, Huanghuai, Jianghan, and western Jiangnan will be 1 to 3°C lower than the same period in normal years. Temperatures are close to normal or slightly higher.

Jiangnan, South China and other places should pay attention to preventing geological disasters that may be caused by continuous rainfall and local heavy rainfall, and do a good job in lightning protection.

Farming and livestock facilities and simple structures in Henan, Shandong, Hubei, Hunan, Guizhou and other places are at risk of being crushed by snow. It is recommended to strengthen and inspect the snow and clear the snow in a timely manner. The degree of excessive soil moisture in the middle and lower reaches of the Yangtze River and some areas south of it is getting worse, which is not conducive to the recovery of growth of rapeseed, economic forest fruits, etc. that were frozen in the early stage. It is recommended to clear ditches and remove moisture in time, reduce humidity and drain away stains, and reduce wet stain damage and early frost damage. superimposed effects.
