With the strong return of the subtropical heat and high pressure, the afternoon temperature in East China and Central China gradually climbed to a pleasant 15, as if the long-lost spring is coming to us. The sun is shining warmly, making people feel the full feeling of spring. But the pace of spring is always in a hurry, and a new round of rain and snow cooling weather is coming, which reminds people of the old saying, spring weather is like a child's face, and it changes when it is said.
In the past 24 hours, all parts of the country seem to have experienced a carnival of temperature, East China, Central China, North China, South China, Southwest, Northwest, Northeast and other places have risen, the highest rise has reached an astonishing 12, and some areas have broken through the 30 mark. However, this warm current is not a long-term solution, as the cold air moves south on the 4th and 6th, the temperature in most parts of the central and eastern regions will drop again, with a cooling range of 4 6 degrees Celsius, and the cooling range in Jiangnan and South China may reach 8 10 degrees Celsius.
While the warmer weekend gave people a brief sense of spring warmth, highs across the South are set to return to around 10 as cold air arrives. This kind of weather that alternates between cold and warm, warm and cold at first, makes people catch a cold if they don't pay attention to it. Some netizens joked that the current season seems to be only summer and winter, and the sense of existence in spring is getting weaker and weaker.
In meteorology, a daily average temperature of less than 10 for 5 consecutive days is defined as winter. However, the weather in Foshan, Guangdong Province and other places is like a TV channel, from December last year to March this year, it has experienced many transitions from winter to summer, as if it is a naughty work of nature.
The day after tomorrow, we will usher in the 24 solar terms. There is an old saying, "If it doesn't rain, you're going to starve to death this year." Sure enough, a wide range of rain and snow across the country has been arranged. **The forecast of the meteorological observatory shows that from tonight to tomorrow during the day, southern Xinjiang, most of the country, southern and western Qinghai, Gansu Province, central Shanxi and central and southern Inner Mongolia will usher in moderate snow or sleet weather, of which the southwest of ** is even more likely to have blizzards. There will be light rain in the central and coastal areas, and moderate rain will also occur in parts of northwest Hunan, central and northern Jiangxi, northwest Guangxi, and northern Guangdong.
Compared to the supercomputer GFS in the United States, the forecast is broadly consistent. However, there are some subtle differences, such as GFS reducing rainfall areas in Henan and increasing snowfall in northeastern Hebei, parts of Heilongjiang, Ningxia, and central and northeastern Inner Mongolia. In addition, GFS has also increased the intensity of snowfall at the junction of Qinghai and Sichuan provinces.
The ECMWF weather forecasting system in Europe retains the ** data of GFS as a whole, and further enhances the precipitation intensity in the central and northern parts of Jiangxi and the northwest of Guangxi, adjusting them to heavy rainfall. This means that Fuzhou City, Yingtan City in Jiangxi, and Qingyuan City in Guangdong will all usher in relatively strong rainfall.
In the context of global warming, the number of extreme weather in China is on the rise. Droughts, typhoons, torrential rains, freezing and other severe weather events have been staged in turn, not only in large numbers and in wide coverage, but also in increasing intensity, breaking historical records repeatedly. According to **, the overall deviation of weather conditions in 2024. From the perspective of the "roller coaster" temperature rise and fall in South China, the subtropical heat and high pressure reached a high level in winter, and it is expected that this summer, there will be more extreme weather such as high temperature and typhoon in the region. In addition, this year's summer precipitation in the south is more than usual, and there are more waterlogs than droughts. At the same time, due to the impact of El Niño events, the overall temperature this summer will be heavier than in 2023. Therefore, we need to prepare for extreme weather in advance to ensure the safety of people's lives and property.
