According to the website of the Central Meteorological Observatory, the latest forecast of the Central Meteorological Observatory is that under the influence of strong cold air, in the next three days, some parts of northern China will experience significant cooling, among which, the cooling range in eastern Xinjiang, central Inner Mongolia and other places can reach more than 4 °C; Different from the previous windy cooling process, this cold air process due to better water vapor conditions, the central and eastern regions will usher in a wide range of rain and snow weather this year, there are regional heavy rains in the south, and the precipitation in Inner Mongolia, Shaanxi and other places will be close to the extreme value of the same period in history, reminding the public to pay attention to the prevention of severe weather.
The Central Meteorological Observatory issued a gale cooling forecast this morning: it is expected that this day and tomorrow, the temperature in most of Xinjiang, most of Inner Mongolia, northwest and east of Qinghai, Gansu, Ningxia, central and northern Shaanxi, northwest Heilongjiang and other places will drop by 4~8 °C, of which the local cooling range in eastern Xinjiang and central Inner Mongolia can reach more than 10 °C; Some of the above areas also have northerly winds of 5~6 and gusts of 7~9.
It is expected that today, rain and snow in the central and eastern parts are poised to start. There was light snow or sleet in most of Tibet, parts of eastern and southern Qinghai, and moderate to heavy snow in parts of western and eastern Xinjiang, northern Tibet, northern and southern Qinghai. Moderate to heavy rainfall in parts of the Hetao region of Inner Mongolia, eastern Tibet, western Hunan, eastern Sichuan Basin, northwestern Yunnan, and most of Taiwan Island.
Starting tomorrow, widespread rain and snow will spread, with moderate to heavy rain in parts of the Hetao region of Inner Mongolia, eastern Tibet, eastern Northwest China, southern and western North China, western Huanghuai, Jianghan, northern Jiangnan, and northeastern southwest China, among which there will be heavy rain or heavy rainfall in parts of southern Henan, northern and southern Hubei, and northern Hunan. It is expected that the main occurrence of this round of rain and snow weather will occur from April 4 to 2.
Meteorological experts remind that this round of rain and snow process will be the largest range of strong rain and snow weather this year, northern blizzard, strong wind, local cold wave and other disastrous weather superposition, southern regional heavy rain, local and accompanied by strong convective weather, the public need to pay close attention to the local meteorological department issued by the forecast, warning information, reduce going to dangerous areas, avoid going out during the period of strong convection active; The heavy precipitation in central Inner Mongolia and the phase transition of rain and snow make wet snow easily lead to the collapse of agricultural facilities such as greenhouses, which need to be defended in advance and cleaned in time.
In addition, since the beginning of this year, the temperature in the central and eastern regions has been significantly higher and the precipitation is low, and this large-scale rainfall is conducive to alleviating meteorological drought, replenishing soil moisture, and is more conducive to crop growth and development.
