There are many heavy precipitation in the south!In addition, the high temperature will come again tomorrow!| Expert interpretation

The Central Meteorological Observatory predicts that in the next two days, the rain belt that affects our country will be obviously lifted north. Guizhou to Jianghan and Huanghuai will appear from west to east to heavy rain. There will be heavy rain in some areas and strong streams such as thunderstorms. The surface of the Huaihe River Basin is relatively large, and there is a risk of super warning water level in small and medium rivers. The Central Meteorological Observatory continued to issue heavy rain blue warning at 18:00 on July 19.

National Chief Predictor, Central Meteorological Observatory, Zhengye Economic Research Senior Engineer Ma Xue Tan Interpretation of this round of weather process

There are heavy rainfall in the influence of strong precipitation

"The precipitation process is mainly caused by the low vortex of the southwest. The low -tank of the plateau led the southwest vortex out and developed, which caused a strong downside on the periphery of the subtropical high -pressure." The Ma Xue model was introduced. During the day, although the duration does not last long, it has the characteristics of extensive influence and strong land rain.

From 14:00 on the 19th to 14:00 on the 20th, Henan, central and southern Shandong, northern Anhui, northern Jiangsu, central and eastern Hubei and southwest, southern Sichuan, northern and southeast of Chongqing, central and western Guizhou, northern Yunnan, northwest of Yunnan, northwestern Guangxi There are heavy rains in some areas. Among them, there are heavy rain (100 to 180 mm) in southern Shandong, northeast Hubei, southern Sichuan, eastern Chongqing, northern and western Guizhou, and northwestern Guangxi. The above -mentioned areas are accompanied by short -term and heavy precipitation (the maximum hourly rainfall is 30 to 60 mm, and the local area can exceed 70 mm).

It should be noted that on the afternoon of the 20th, the unstable energy of the central and eastern parts of Jiangsu should be alert to the extreme thunderstorms that may occur in the local area.

Pay attention to secondary disasters such as flood landslides in the short -term stubborn precipitation

In the process of precipitation, some areas have a large amount of precipitation, especially in southern Shandong, northeast of Hubei, southern Sichuan, central and western Guizhou, etc., to prevent short -term precipitation. Especially in mountainous areas, we must pay attention to secondary disasters such as floods, mudslides, and landslides that may cause sudden precipitation to prevent the floods of small and medium rivers that may cause.

In the next three days, it is expected that the rainfall in the Shengsi Basin of the Huaihe River is 40 to 80 mm, and the rainfall above the Huaihe River Travel County is 50 to 70 mm; 40 to 90 mm; the risks of floods in medium and medium rivers in the above areas are high.

The Ministry of Water Resources and the China Meteorological Administration jointly issued an orange mountain flood disaster meteorological warning at 18:00 on July 19: It is expected that from 20:00 on July 19 to 20:00 on July 20th, southeast Henan, northeast Hubei, southern Sichuan, western Guizhou, and western Guizhou, and western Guizhou, and western in Guizhou, The possibility of flood disasters in parts of the northern part of Yunnan (yellow warning). Among them, southeast Henan, northeastern Hubei, southern Sichuan, western Guizhou, and northern Yunnan areas are likely to occur in mountain flood disasters (orange warning).

It is expected that starting from the 21st, with the eastward movement of a cold air, some areas in the central and eastern parts will also have a relatively obvious precipitation process from west to east. The stack of precipitation areas is high, and the impact of secondary disasters should be paid attention to.

After the southern brief cooling, it will appear again to continue high temperature weather again

Since July, with the influence of the high pressure of the Western Pacific subtropical high pressure, under the influence of factors such as Qingtong radiation and sinking temperature, the high temperature in the south has continued to develop, showing the characteristics of significant extremes, extensive influence, and long duration, etc. Essence

Affected by rainfall, the overall intensity of the high temperature in the southern region in the next three days has weakened and the scope is reduced. Especially in some areas of Sichuan Basin, Guanzhong, and Jiangnan in Shaanxi, due to strong precipitation, high temperature will significantly retreat, and drought will also be effectively eased. However, coolness is short. It is expected that starting from the 21st, the subtropical high pressure will be strengthened again and opened with the mainland. Affected by it, the southern region of my country will still have high temperature weather above 35 ° C in the future, and the large -scale high temperature in the northern region will also be launched.

At the end of July, Sichuan Basin, Jianghan, Jianghuai, Jiangnan, South China and Xinjiang Southern Xinjiang Basin, western Inner Mongolia and other places will appear with a large range of high temperatures above 35 ° C. The temperature can reach above 40 ° C; there will be intermittent high temperature weather in central and southern North China, Huanghuai and Shaanxi. In addition, it is expected that in late July, the rainfall in central and southern South China and central South China is less than the same period of the same year. Affected by the continuous high temperature and rain, the drought of weather in Zhejiang, Jiangxi and other places may continue to develop.

Meteorological experts remind that because the southern region is large and the temperature is high, the physical sensation will be very uncomfortable. It is necessary to pay attention to the adverse effects of continuous high temperature on the supply of human health and power. It is recommended that the public should take measures to prevent heatstroke and cool down to avoid heat stroke or heat irritation. Pay attention to preventing forest fires; all parts of the south should make preparations for drought resistance in advance to prevent the adverse effects of water resources on agriculture and production and life.
