The Hangzhou Meteorological Observatory issued a cold wave warning signal this afternoon, severe cooling, strong winds, rain and snow are coming.
City Express News At 6:00 am yesterday, the Central Meteorological Observatory updated the cold wave yellow warning to the highest cold wave orange warning level.
According to the content of the advisory, this strong cold air will affect most of the central and eastern regions of China from west to east and north to south, bringing strong winds and strong cold weather. From yesterday until the 31st, the temperature in most of the central and eastern regions will drop by about 10 ℃, and the temperature in the eastern part of the northwest region, the southeast part of the northeast region, western and northern China northern, southern Huanghuai, Jianghuai, Jiangnan and central and northern southern China will drop 12-16 ℃, the temperature drop in some areas may reach more than 16 ℃. After the temperature drop, the 0 ℃ line of the lowest temperature will press south to the northern part of southern China, and the lowest temperature -10 ℃ will be from the lower reaches of the Yellow River to the mountains Qinling.
At 2:06 p.m. yesterday, the Hangzhou Meteorological Observatory also issued a blue cold wave warning signal. It is expected that starting this afternoon, due to the cold wave, our city will experience a process of strong temperature drop, strong wind and rain and snow. The rain is expected to turn to sleet or snow in the afternoon to night, and there will be moderate to heavy snow in the mountains. The process average temperature can drop between 11 and 13 ℃. On December 31, 2020 and January 1, 2021, the minimum temperature in the flat areas will drop from -6 ° C to -4 ° C, and in the mountainous areas it will drop from -10 ° C to -6 ° C. There will be severe frosts. Please take precautions.
China Weather Network stated that this is the first time that the Central Meteorological Observatory has issued an orange cold wave warning in 2016. Looking through the records, there are not many cold waves that can reach the orange alert level. Friends, Take out your thick winter clothes and put them on.
From tonight there will be sleet or snow in the city.
It is worth noting that compared to the past few days, the latest forecast from the Hangzhou Meteorological Observatory has made two adjustments. The first is that the cooling speed has been increased: the process cooling speed has been increased from the original 9-11 ° C to 11-13 ° C. The second is the improvement of the wind force: the maximum wind North on the plains has increased from 6-8 to 7-9, and the mountain and rivers and lakes have also increased from 8-10 to 9-11.
From these two adjustments, it can also be found that the impact of the cold wave is more severe than originally expected.
According to the analysis of the Municipal Meteorological Observatory, this year’s cold wave compared to 2016, although the degree of cold is not as good as in 2016, the temperature drops faster and more violently. The highest temperature today is still 13 ° C, but after tomorrow it will drop to near freezing, and the lowest temperature will drop from -6 ° C to -4 ° C.
If the 2016 cold snap is a protracted battle, then this year’s cold snap is a swift battle. It exploded to the south, attacking the city at lightning speed, wherever it went, it was instantly freezing, causing people to be caught off guard.
In addition, due to the rapid advance of the cold wave, the precipitation in various places is relatively “simple” from rain to snow, but the whole precipitation process is also very fast, and the precipitation time in the same place can be even less than a day. Tomorrow, this extensive rain and snow will end quickly, and most of the country will usher in good weather.
Meteorological experts recalled that although the intensity of rain and snow caused by this cold snap process is not as strong as the “Supreme Lord” cold snap in January 2016, the relevant departments and the public in the Central and eastern regions, especially Henan, Hubei, Jiangsu and Anhui, still need to pay attention to avoid the adverse effects of snow on roads and icing on traffic.
The rainy and snowy weather in Hangzhou is also relatively short. The entire city is expected to turn to rain this afternoon, turning to sleet or snow from the mountain to the plain from afternoon to night. In the middle of the night, the rain and snow will stop everywhere, and there will be almost no snow in the flat areas, there will be 2-5 cm of snow in the mountainous areas and 5-8 cm in the high mountain areas.
