Hangzhou will be in spring tomorrow!

It is estimated that from today (March 1), the sliding average temperature in Hangzhou will exceed 10 ℃ for five consecutive days, entering the spring in the sense of meteorology.

Is spring early this year? Compared with the perennial spring time in Hangzhou (March 10), it is naturally early, but not very early. Meteorological records show that since continuous observation records in 1951, the earliest time of spring in Hangzhou is February 5, 2007, followed by February 13, 2004, the third is last year, and spring begins on February 20.

In the context of global warming, “spring girl” is becoming more and more anxious. According to the statistics of the Provincial Meteorological Observatory, the date of spring in Hangzhou has generally been early since the 21st century. From 1951 to last year, 11 years entered spring in February, including 6 years after 2000.

Hangzhou’s spring often survives in the gap between summer and winter. Compared with the 132 day summer and 103 day winter, the average length of Hangzhou’s spring is only 71 days. If you buy spring clothes, you have to hurry up and wear them. Don’t waste it.

It’s spring. Can I take off my cotton wool pants?

As the saying goes, “spring covers autumn”. In terms of climatology, because spring is in the warming stage, as soon as the weather clears up, the temperature will rise sharply, but at this time, the human body’s regulatory function does not adapt to the rapid changes of the weather. If you don’t pay attention, a cold will take advantage of it.

According to meteorological records, the temperature difference in spring can sometimes be surprisingly large. For example, on March 19, 2010, the daily maximum temperature in Hangzhou was 31.4 ℃, the daily minimum temperature was 6.9 ℃, and the temperature difference reached 24.5 ℃.

So the most suitable season is “onion dressing”. The so-called “onion dressing”, as the name suggests, is like onions layer by layer. The inner layer can wear clothes with good perspiration function, the middle layer can keep warm, and the outermost layer is waterproof and windproof to cope with weather changes. The combination of field of view and temperature can be added or removed layer by layer.

Did you take off your thick coat today?

Although appropriate “covering” is beneficial to physical and mental health, we should not “cover” too tightly. When the minimum temperature is higher than 10 ℃, you can consider cotton wool pants. Of course, whether you take off your cotton wool pants or not depends on whether you feel cold or not. After all, everyone’s cold tolerance is different. There is a saying that “if you drink water, you know the cold and warm”.

There are two streams of cold air coming soon

The temperature continues to rise in most parts of the country. China weather network predicts that the temperature in many places in the South will set a new high this year. The highest temperature in Nanjing, Changsha, Nanchang, Wuhan and Hefei, including Hangzhou, may exceed 20 ℃.

But a new cold air has set off. This cold air will first affect the northwest, the West and north of North China, and will quickly go south to the north of South China tomorrow.

Although this cold air force is not strong, due to the obvious temperature rise in the early stage, the temperature will also drop significantly. The temperature is expected to drop by 4 ~ 8 ℃ successively, and the maximum temperature drop in some parts of the South can reach more than 10 ℃. The good news is that the cold air comes and goes faster this time. The cooling is short. It will basically drop for one day, and then the temperature will rebound.

On April 5, there will be another cold air. The temperature in most parts of the Middle East will drop by 4 ~ 8 ℃ from north to south, and the local cooling range can reach about 10 ℃.

This week, the temperature fluctuation in most parts of the country will be more frequent, but generally it is still warmer than the same period of the year. For example, in the Yangtze River Basin, even if it is cooled, the maximum temperature will be around 15 ℃.
