Prevention of urban weather forecast

At the weekend, many places in South China will return to 20 C, and the local area may be overheated.

At the weekend, many places in South China will return to 20℃, which will be locally or excessively hot. Tomorrow, as the rain and snow weather in the south subsides, the sun will gradually go online and the low temperature will ease. At the weekend, many places in South China will return to 20℃, which will be locally or excessively hot.

Over the weekend, many places in South China will return to 20℃, with local overheating 1. On February 22nd, many places in South China, where cold air, rain and snow were unusually cold recently, were still in a wide range of wet and cold atmosphere. For example, in Guangdong, the coastal area of South China, the lowest temperature from February 2/kloc-0 to February 22 is generally less than 10 degrees, and the lowest temperature in many places in central and northern Guangdong is even less than 5 degrees, such as the source of Qingyuan River in Shaoguan. In many places, the lowest temperature is only 2-3 degrees, and there are still low-temperature freezing phenomena in some places.

Although the temperature along the coast of South China has risen slightly today, the extent of the rise is actually not very large. Similarly, the highest temperature monitoring data from February 2/kloc-0 to February 22 shows that the highest temperature at existing stations along the coast of Guangdong has risen above 10, but only in the early stage of 10. The daily maximum temperature in many places in the Pearl River Delta and northern Guangdong is still below 10 degrees. It can be said that this is the strongest cold wave in late February in Guangdong and Fujian since 1996.

Even in southern coastal provinces such as Guangdong and Fujian, the cold in other southern provinces is inevitable-Yunnan on the Yunnan-Guizhou Plateau, the temperature was low from yesterday to today, and even snowflakes were falling. For example, Kunming, the "spring city", is snowing in many places in Kunming today, and there is obvious snow near the ground. As one of the representatives of the dry-hot valley, Yuanmou weather station in Yunnan also recorded the arrival of snowflakes rarely this morning.

The snow in Kunming comes from Weibo netizen @ Bran Epic.

In fact, this is a microcosm of the whole wet and cold February. Although there was no nationwide cold wave heading south in February this year, intermittent cold air infiltrated and superimposed with active water vapor background, which led to a wide range of rain and snow weather in central and eastern China. The temperature in many places in the rain and snow is extremely low, and many netizens feel colder than "3949". According to the monitoring data of abnormal temperature in the National Climate Center of China Meteorological Bureau, the temperature in most parts of China has obviously turned cloudy since February, especially in North China, Qinghai-Tibet, Southwest China, Jiangnan and South China, which are more than 4 degrees lower than normal. Especially in the next few days, most of the south of the Yangtze River, South China, Yunnan and Qinghai-Tibet Plateau will continue to be low. It can be said that this is an out-and-out "cold February".

Will this situation last until March? According to the forecast made by the Central Meteorological Observatory before March, it is predicted that the temperature in most parts of China will turn from low to high. For example, the mid-range weather forecast on February 22nd pointed out that in the next 1 1-20 days (March 4th-13rd), the average temperature in parts of Yunnan and Qinghai-Tibet Plateau will be slightly lower than normal.

However, some areas in the south may be too warm-for example, in Guangdong, some cities have pointed out the warming in the next few days in February, and it will be warmer by 8- 15 days in March. Zhaoqing, Guangdong even reported the highest temperature of 30 degrees on March 5. Although this warmth is not unusual for Guangdong, it may represent the overall improvement of atmospheric capacity in South China, and the possibility of severe convective weather outbreaks may increase rapidly.

At the same time, some supercomputers also predict that in the next recovery period, some southerly water vapor will go northward, which may also bring some areas back to the south, such as Guangdong and Guangxi, which have been completely cold recently. But on the whole, the next recovery is mostly accompanied by clearing up, and more often the south wind is weak, so it should still be impossible to return to Nantian on a large scale.

At the weekend, many places in South China will return to 20 C, and the local area may be overheated. From tomorrow, as the rain and snow in the south subside, the sun will gradually go online and the low temperature will be alleviated. Most areas will usher in a wave of obvious warming, and the temperature will turn from low to high. The temperature forecast map has obviously warmed up this weekend. The highest temperature 10℃ will push northward to the northern part of North China, and the area from North China to the middle and lower reaches of the Yangtze River will usher in a high temperature this year. Among the provincial-level cities, the highest temperature in Hangzhou today and tomorrow is less than 5℃, but it can rise above 16℃ around the weekend, and the cumulative increase will exceed10℃; Guangzhou and Fuzhou will rise from single digits to above 20℃.

From the afternoon of February 23, with the eastward movement of precipitation cloud system, the wet, cold, rainy and snowy weather lasted for more than a month, and finally it was going to leave the south. The south will join the north in welcoming bright sunshine and rapid temperature rise. Among them, Guangdong, Guangxi, Hainan and Fujian have the fastest temperature rise, and Guangdong and Hainan may return to the state of short sleeves at noon within one week. Of course, there is a price, that is, there may be a short part of the return to Nantian.

The low temperature in China on February 20th comes from NMC.

Although the temperature in other places will obviously rise, with the formation of a new round of south branch trough, there may be rain in the south of the Yangtze River, and the temperature will rise and fall. But in any case, with the westerly belt shrinking faster than expected, it will quickly withdraw from the south in winter, and China will return to a warmer or even warmer state in early March. Please adjust your clothes quickly and get ready.

Many places in South China will return to 20℃ on weekends, and it will be local or overheated. Today (February 22), there is still a large range of rain and snow in most parts of the south, and the boundary between rain and snow will be further pressed southward to the southernmost point of winter, and pure snow will appear in Guizhou and Hunan. Starting from tomorrow, the range of precipitation in the south will be rapidly reduced, sunshine in many places is expected to "show up", the temperature will gradually rise, and the highest temperature in most parts of South China will rise to double digits.

One more day! There is still a large range of rain and snow in the south today, and many places will be sunny.

In mid-February, there were frequent rainy and snowy weather in the south, especially in Guangxi and Guangdong. Guangxi broke the historical record in mid-February since 196 1, and Nanning, Fusui and Fangchenggang broke the record at 19. In just two days, it rained for a month in February all the year round. From February 19 to 20, the accumulated rainfall in Guangzhou and Shenzhen exceeded110mm.

Yesterday morning, it was rainy and foggy in Nanning.

There is still a large range of rain and snow in the south today, and the snow line will continue to press south, reaching the southern part of Guizhou and Hunan, close to the southernmost point since this winter. The Central Meteorological Observatory predicts that there are small to medium snow or sleet in parts of eastern Jilin, western mountainous areas of southern Xinjiang Basin, western and southeastern Tibet, southeastern Qinghai, southern Gansu, southwestern Shaanxi, western Sichuan Plateau, northwestern and northeastern Yunnan, southern Guizhou, southern Hubei, northern Jiangnan and other places. Among them, there are heavy blizzards in parts of northeastern Yunnan, north-central Guizhou, central Hunan and northwestern Jiangxi, with local blizzards (20-25mm). There are small to moderate rains in parts of central, eastern and southern Jiangnan, central and southern Yunnan, southern Guizhou, southern China, Hainan Island and Taiwan Province Island. Among them, heavy rain (25 ~ 40mm) occurred in parts of eastern Fujian, eastern Guangdong and northern Taiwan Province Island.

Tomorrow, with the weakening of cold air, the precipitation in most parts of the south will rapidly weaken and contract. It is estimated that there will be small to medium snow or sleet (2.5 ~ 4 mm) in parts of western mountainous areas of southern Xinjiang, central and western Tibet, southwestern Qinghai, southern Gansu, eastern Sichuan Plateau, northeastern Yunnan, western Guizhou, southern Anhui, northeastern Jiangxi and central and northern Zhejiang. There are small to moderate rains in parts of western Sichuan Basin, south-central Yunnan, southeast coast of Guangdong, south-central Jiangxi, southern Zhejiang, Fujian and Taiwan Province Island, among which there is heavy rain (25-30mm) in parts of northern and eastern Taiwan Province Island.

Starting tomorrow, most of the rain and snow in the south will shrink rapidly, and many places are expected to usher in the long-lost sunshine. Until the weekend, most of the central and eastern regions will usher in a period of precipitation intermission. However, due to the long duration of rain and snow in the early stage, the accumulated rainfall in South China is relatively large, and the occurrence of geological disasters lags behind, especially in most areas of Guangdong and Guangxi.

Since the Ming Dynasty, most areas in the south started the warming mode, and many places in the south returned to 20℃ on weekends.

From tomorrow, as the rain and snow weather in the south subsides, the sun will gradually go online and the low temperature will be alleviated. Most areas will usher in a wave of obvious warming, and the temperature will turn from low to high.

This weekend, the highest temperature 10℃ will be pushed northward to the northern part of North China, and the area from North China to the middle and lower reaches of the Yangtze River will usher in a new high temperature this year, and the warmth will return. Among the provincial-level cities, the highest temperature in Hangzhou today and tomorrow is less than 5℃, but it can rise above 16℃ around the weekend, and the cumulative increase will exceed10℃; Guangzhou and Fuzhou will rise from single digits to above 20℃.

Due to the severe wet and cold in the early stage, the basic temperature in most parts of the south is low, the temperature rise is large, and the temperature difference before and after is very obvious. The public in these areas should pay attention to increasing or decreasing clothes in time to prevent colds.
