Will Zhejiang be particularly cold this winter?Here comes the answer
Daily Business Daily News Last week, Hangzhou won the “Good Weather Attendance Award”. The sun was shining and the temperature was right. It’s a pity that the good weather entered the countdown with the “opening” in November, and the warm and humid air and cold air that had disappeared for a long time became “restless” again.
Yesterday morning, there was a light rain in Hangzhou from west to east. There was no greeting from the sun, and with sporadic rain, the chill came back in an instant.
The weather in Hangzhou in the coming week will have two key words: rainfall and cooling.
Hangzhou is mainly overcast and rainy before the week
The lowest temperature drops to single digits next Monday
Yesterday, the warm and humid air flow “tested a sledgehammer”. Although the lowest temperature in the main urban area reached 17.2℃, the body felt wet and cold.
The Municipal Meteorological Observatory said that before this Sunday, Hangzhou was basically overcast and rainy. Among them, from Thursday night to Friday, there will be moderate to heavy rain, and the precipitation will be more obvious. Visibility is poor in rainy weather, and there is fog or haze in some areas. Please pay attention to safety when you travel.
Next Monday, as the cold air moves south in one fell swoop, it will take away the warmth and rain. The weather will turn fine. In addition to cold, fine weather will return again.
Let’s talk about the temperature. The temperature changes little before Saturday, and the highest temperature remains at 18-22°C. However, starting from Thursday, there will be a strong cold air moving eastward and southward, beginning to affect most parts of our country. The time when the cold air arrives in Hangzhou is on Sunday night, when the temperature will drop sharply.
From Sunday to next Monday, there will be a drastic cooling, rainfall and windy weather in Hangzhou. Specifically, the highest temperature on Sunday was still 20°C, but by next Monday, the lowest temperature plummeted to 7°C, and the highest temperature was 13°C. With strong wind and rain, the human body felt even colder.
In general, it is expected that the number of cold air processes in November will be more frequent, the intensity will be stronger, and the temperature will be lower. Everyone should prepare in advance for the defensive cooling process, especially for thick clothes. You can prepare in a few days. NS.
Zhejiang’s temperature this winter is normal or slightly higher
The overall precipitation is low
Recently, the official China Meteorological Administration announced: The La Niña incident will take shape! This is after the end of the last La Niña incident (from August 2020 to March 2021), the La Niña incident has been formed again. In other words, the “Bimodal La Niña” occurred in winter for two consecutive years. Many friends said, will it be particularly cold this winter?
Lei Yuan, a senior engineer from Zhejiang Climate Center, said that the winter temperature in our province this year is normal or slightly higher, but the overall temperature is lower than the previous year. Cold air activities are more frequent, and there is a higher probability of strong cold events such as strong cold air and strong cold waves. .
“This winter may not be as cold as a whole on average, but there are a few days of extreme cold, which is expected to occur from mid-to-late January to the first half of February.” Lei Yuan said.
Compared with last year, this year’s extreme cold may be later, and the degree of cold may reach the same level, but extreme weather events are still difficult to say, and it is more difficult to predict.
In addition, it should be noted that there is relatively little precipitation in winter this year. Since September, the precipitation in some areas of western Zhejiang has been less than 20%. Moreover, western Zhejiang is the location of most of the large reservoirs in our province. The precipitation continues to be low in autumn and winter. Water management will have an impact.
As for the La Niña incident that lasted for two years, and La Niña again in the second year, the atmospheric circulation will respond more fully to it and more obvious. So overall, the weather characteristics this year will be more extreme than last year, and the cold range is seen from the whole country. It will be a little bit bigger than last year, the degree of coldness in Zhejiang will be stronger than last year, and the probability of extreme events will be greater.
