On the afternoon of February 4, from the cloud map of the Fengyun-4 high-definition visible light satellite, although there are still many rainy clouds in the southern part of the mainland today, the scope and significant reduction compared with before. For example, many places in Hubei, Hunan, Guangxi, and Guangdong, which were once soaked in rainy, wet and cold weather, have been sunny in many counties and cities on the satellite cloud map today, and the sun is on the line.
Therefore, under the clear sun, the wet and cold feeling in many parts of the south has faded a lot. For example, on the 24-hour temperature change map at 14:00 p.m., the temperature in many places south of the Yellow River on the mainland today has risen significantly, and the 24-hour heating rate of some stations has reached about 8 degrees, which can be said to be significantly warmer than today at the same time yesterday.
For example, in South China, where it was wet and cold before, the temperature map at 14 o'clock showed that the temperature in many parts of Guangxi and Guangdong had returned to more than 10 degrees this afternoon at 14 o'clock, and the rain had weakened, and the body feeling warmed up significantly. On February 4, 2022, at 04:50:36, the sun has a yellow longitude of 315°, and the Spring Festival has arrived. As the name suggests, the Spring Festival is the day of the establishment of spring, as the first of the twenty-four solar terms, many people think that from the beginning of the Spring Festival, the spring has begun, and today the temperature of the sun in many places in the south has warmed, which is indeed very corresponding to the Spring Festival.
However, according to the definition of climate, it is still winter (December to February), and the recent temperature in many places in the south of the mainland is too low, completely unable to meet the meteorological spring standard of five consecutive days with an average daily temperature of more than 10 degrees, so although the Spring Festival does come, many places are still winter. So starting from the Spring Festival, will there be more places to enter the spring? According to the trend of time, this is certainly the case, but it may not be realized in the short term, this is because, as the southern branch trough south of the Qinghai-Tibet Plateau is gradually in place, the water vapor transport in the central and eastern parts of the mainland is about to strengthen, and a wide range of rain and snow weather will come again.
The forecast of the Central Meteorological Observatory pointed out that from February 5 to February 7, the central and eastern parts of the mainland will face a large-scale rain and snow weather process, in which most provinces, autonomous regions and cities in the south will also be fully immersed in rain and snow weather, and many provinces, autonomous regions and cities in the middle and lower reaches of the Yangtze River may have the possibility of drifting snow.
For example, in Wuhan, Hubei Province, which has warmed up today, the official forecast has pointed out that the rain and snow will be online again around February 6, and there may be moderate snow weather. And from February 6 to February 10, there will be rain and snow, and the temperature will be quite low, so although the Spring Festival is coming, the real spring has not fully appeared in the south.
