Reading guide: Tomorrow is March 27th, the eighteenth day of the second lunar month, the cold air is coming again, the range of heavy rain, blizzard, hail has been determined, and the spring cold that has not been encountered in 60 years is coming?
On March 26, many places in Zhejiang ushered in rare hail weather. Cars were smashed through the hailstorm in the most severe areas, which shows how serious the natural disaster of this hailstorm was. Despite a little rain, hailstones the size of duck's eggs fell from the sky, and some people were bleeding from their heads. As for the leaves of the plants, the crops in the field were smashed to a mess, and it can be said that the yield was greatly reduced.
The main reason is that the strong warm and humid air flow in the south and the strong cold air in the north work together to form a strong convective weather. After the spring equinox, the mainland suddenly ushered in a wide range of warming, especially in the south of the Yangtze River, Jianghuai, and Huanghuai, and the temperature was 4~6 degrees higher than that of normal years. Due to the relatively strong force of cold air, the bad weather that formed a strong convection also appeared this big hailstorm, which can be said to be a once-in-a-century occurrence.
What is the weather forecast for tomorrow, March 27th?
Under the influence of this strong cold air, the amplitude and scope of tomorrow's rain and snow weather will increase further, and the key is the increase in precipitation.
Tomorrow's heavy snowfall or rain process seems to make everyone think that the spring cold is coming, but the reality is that this is only a temporary strong convective weather, and it can only last for two days, followed by rain and snow, and the temperature drop is not particularly powerful.
It is expected that tomorrow under the influence of cold air, the temperature in northern North China, the central and eastern parts of Inner Mongolia and Northeast China will drop by 4~6 °C, and the local temperature will drop by 8~10 °C, and some of the above areas will be accompanied by 4~6 winds, with gusts up to 7~9.
Snowfall: Light to moderate snow or sleet is expected in eastern Inner Mongolia and northern Heilongjiang, with locally heavy to heavy snowfall, with a maximum snowfall of 17 mm. There is light to moderate snow or sleet in the mountainous areas of western Xinjiang and the eastern part of the western Sichuan Plateau.
In terms of precipitation: light to moderate rain in Northeast China, northern and eastern southwest China, Beijing, northern Hebei, northeast Tianjin, central and southern Jiangsu, Anhui, southeastern Henan, Hubei, Shanghai, Zhejiang, northern Fujian, Jiangxi, Hunan, northern Guangxi and other regions, with heavy to heavy rain, heavy rain or extremely heavy rain in local areas. Among them, there were heavy rainstorms or extremely heavy rains in western Zhejiang, southern Jiangsu, southern Hubei, northern Jiangxi, Hunan, eastern Guizhou and other regions, accompanied by strong convective weather such as hail.
The cold spring that has not been encountered in 60 years is coming? What does the rural proverb say?
The weather is cold in mid-February and cold until the end of the month in March
February and March refer to the February and March of the lunar calendar, respectively, and the times mentioned in ancient times were both lunar calendars. Because the mainland used the lunar calendar system in ancient times, it was only after the founding of the People's Republic of China that the Western solar calendar was adopted, mainly because the time was in line with international standards.
This proverb means that in the middle of the second month of the lunar calendar, the weather is cold, that is, long-term low temperature or snow, indicating that the day is still cold in March and will be cold until the end of the month, which indicates that the cold spring is coming.
The inverted spring cold generally occurs during the period from the end of March to the beginning of May in the solar calendar, that is, in the two solar terms of mid-spring and late spring. Especially around the Qingming Festival is very serious, and the inverted spring cold will occur every year, which is nothing more than a matter of severity.
The significant feature of the inverted spring cold is that long-term low temperature will cause frost damage to crops and other plants, such as long-term rain, and even snow, and the phenomenon of spring frost is also more serious!
As far as the current weather on the mainland is concerned, although the cold air activity is frequent, and the feeling of being warm and cold at first, the temperature has risen very quickly recently, the grass and trees have sprouted, the flowers have bloomed, and the spring is full of joy. Moreover, in addition to the northwest region and the Sichuan-Tibet Plateau, the temperature in the mainland is lower than that of normal years, and other places are 2~6 degrees higher, so it is not yet the arrival of the spring cold!
All in all, this spring has a special climate. Although the inverted spring cold is not particularly serious, the natural disasters caused by strong convective weather are very serious, such as the recent huge hail in the south of the Yangtze River, which is more severe than the loss of the inverted spring cold!
