Foreword: "The wind in the courtyard falls and the flowers fly, and the lotus pond is fragrant with grass", tomorrow on April 27~30, a new round of heavy precipitation center will be determined, where are the heavy rain and torrential rain distributed? Let's find out.
Today is April 26th, the eighteenth day of March of the lunar calendar, according to the method of the ancients, the third month of the lunar calendar is also known as the March of Yangchun, although it has entered the end of spring, but the spring at this time is strong.
As far as the eye can see, the flowers and trees are full of fragrance, the willow flowers are flying everywhere in the air, in this spring in March, which is so thick that it can not be dissolved, it is "the spring flowers are flourishing, and the scenery is all along the way", and the earth is full of vitality and style.
In fact, every year around the beginning of summer, only the central and southern parts of the Yangtze River in the mainland, as well as the South China region, are considered to be really starting to enter the summer, and most of the rest of the region is still in the spring and late spring season of "sunny and warm wind, all things are beautiful".
Temperature changes and cold air fluctuations before May Day:
Since the end of April, a large number of rain clouds have accumulated over the southern region, causing heavy rain and heavy rain in most areas of Jiangnan and South China, accompanied by strong convective weather such as thunderstorms, strong winds, short-term heavy precipitation or hail.
In many places in Northeast China, North China and Northwest China, these two days are in the spring sunshine, the temperature continues to rise in the weather conditions, of which the temperature in many places rebounded by 6~8 °C, the maximum local temperature rise of more than 10 °C, the weather is warming to hot signs are very obvious.
In the next few days, under the influence of a strong hot and dry air mass moving northward, a strong wave of temperature rise will be set off in many places in the central, eastern and northern regions, coupled with the increasingly weak cold air activity at this time, the intensity and scope of the impact on the weather have become very limited.
So, tomorrow, April 27~30, where are the heavy rains and torrential rains distributed?
By tomorrow's April 27th, the heavy rainfall in Jiangnan and South China will continue, especially in parts of central and eastern Guangdong, southern Fujian, and southern Jiangxi.
On April 28, the day after tomorrow, under the combined influence of the westerly trough and the cold vortex, a large amount of water vapor carried by the warm and humid airflow was blown away, and the heavy rainfall area in the south changed, mainly in the northern part of North China, most of the Jianghuai River, the central, eastern and southern parts of the Yangtze River, the eastern part of Southwest China, and the central and eastern parts of South China.
In some areas of central and northern Guangdong, western Fujian, southwestern Hunan, and southern Jiangxi, there were heavy rains.
Immediately following April 29~30, there were moderate to heavy rains, local heavy rains or heavy rains in local areas of Jianghuai, eastern Jianghan, Jiangnan, South China, Sichuan Basin, Chongqing, Guizhou and other places, and the above places were accompanied by strong convective weather.
It can be seen from the above that in the next few days, with the fierce confrontation between the subtropical high and the warm and humid airflow, the rain will intensify again in many areas in the south, and the Liangguang, Fujian and Jiangxi areas will still be the center of heavy rainfall, and there will still be patches of heavy rain and heavy rain in some areas.
Especially two days before the holiday, the scope of heavy rainfall in the south has gradually narrowed, and many places have changed from heavy rain to moderate rain, and the weather in many places in the central and eastern regions and the north has continued to warm up, and the late spring weather with fresh wind blowing and warmth makes people feel the beauty and happiness of the four seasons.
