Before August 23rd, the south of the Huaihe River will continue to be sunny, hot, high -temperature, and drought will develop rapidly.

According to the public account of the Anhui Meteorological Observatory, since the plum, our province has the characteristics of high temperature and rain and rain. Due to the low rain in the early stage, there is still no effective precipitation south of the Huaihe River before August 23, and the extension of continuous high -strength high temperature weather is superimposed. Southern meteorological drought will develop rapidly.

1. Since the plum, our province has appeared on high temperature and rainy weather characteristics

1. The temperature is significantly high, and the number of high temperature days is the second most in the same period.

Since the plum (July 11th -August 8th), the average temperature in our province is high at 30.1 ° C, which is significantly higher than the same period of the same year. The same period is 9 days, which is the second most in the same period; the eastern and southern parts of Jiangnan is generally more than 25 days, and Xuancheng City and Tunxi have been in 28 days. Of these, 17 counties (cities) are the most historical in this site. The high temperature duration is long. From July 8-16 and August 1st, there are two continuous high -temperature high temperatures. Among them, the high temperature on August 2-8 basically covers the province. 46 % of the counties (cities) on the 8th exceeded 38 ° C, the highest Ma'anshan 41.2 ° C, the third highest in August.

2. The precipitation is nearly 40 %, and the south of Huaihuai River appears light to medium drought

The average precipitation of the province was 94 mm, which was nearly 40 % less than the same period (153 mm). Among them, there was basically no precipitation since August. Meteorological droughts along the south of Huaihuai River. Among them, Fuyang, Liu'an, Hefei, Luzhou, Ma'anshan, Wuhu, Xuancheng, and Huangshan appeared in the middle of drought, and the territory was heavy. The monitoring of the intensity index of the drought process of the comprehensive risk of meteorological disasters — the drought process intensity index shows that Feixi, Feidong, Shucheng, Lujiang, Tianchang, and the drought process reaches the "strong" level.

2. It is expected to be south of the Huaihe River on August 23 to continue to be sunny and hot

Precipitation: It is expected that the province's precipitation will be less than the usual year from August 9th to September 7th, among which more than 20 % south of the Huaihe River is more than 20 %. During the period, there were two precipitation processes, and it appeared on the night of August 15th to 18th (along Huai Huaibei) and 24-26 (province).

Cumulative precipitation: 80 to 100 mm along Huai Huaibei and Dabie Mountains, 40 to 60 mm in other areas.

High temperature: From August 9th to September 7th, the average temperature in the province is 1-2 ° C higher than usual. It is expected that from the south of the province and 16-22 on the 9th to 15th, the high temperature and high temperature weather along the Huaihuai River is mainly 37-39 ° C, and some cities and counties exceed 40 ° C. After the 22nd, extreme maximum temperature: 35-37 ° C along Huaihuai North, 36-38 ° C in the south of the Huaihe River.

Third, countermeasures and suggestions

Since the plum, the precipitation of our province has been nearly 40 % less than that of the year. It is expected that there is no effective precipitation south of the Huaihe River before August 23, and there is a large range of sustainable high -strength and high temperature weather. It will bring a series of adverse effects to various industries.

1. Continuous high temperature and drought have adverse effects on urban water supply, power supply, and municipal transportation, strengthen the management of water resources, and do a good job of water storage and water retention.

2. It is necessary to prevent the adverse effects of high temperature and dry superposition on autumn grain crops such as one season.

3. Preventing high -temperature heat waves lead to increasing risks of electric wires, transformers, forests and urban and rural fires, and increased production accidents and traffic accidents. Please pay attention to prevention.
