What is expected to be done to maintain high temperature and low rainfall in arid areas in the next three days?

It is estimated that in the next three days, in order to maintain high temperature and little rain in dry areas, it is necessary to do a good job in drought emergency work, such as dispatching all available water sources within the jurisdiction, giving priority to ensuring domestic water for urban and rural residents and drinking water for livestock, saving water, and limiting unproductive high water consumption and service water.

According to relevant media reports, the Central Meteorological Observatory issued an orange warning of meteorological drought on August 20 18. According to the meteorological drought monitoring on August 20th, moderate and above meteorological droughts occurred in southern Jiangsu, southern Anhui, southwestern Henan, western Hubei, most of Zhejiang, most of Jiangxi, most of Hunan, most of Guizhou, most of Chongqing, most of Sichuan, southeastern Gansu and central and eastern Tibet, and the scope of severe and above meteorological droughts in many provinces (autonomous regions and municipalities) was significantly expanded. It is predicted that in the next three days, most of the above-mentioned dry areas will still maintain high temperature and little rain, and meteorological drought will continue to develop.

My friends and I learned that since the summer of this year, there have been many high temperature days in China, covering a wide range, and the highest temperatures in many places have exceeded the historical limit. For example, since late July this year, high-intensity and high-temperature weather has appeared in the middle and lower reaches of the Yangtze River. On August 12, the Central Meteorological Observatory issued the first high-temperature red warning this year. As of 13, the Central Meteorological Observatory has issued a high temperature warning for 24 consecutive days. According to the meteorological drought monitoring of the Central Meteorological Observatory on August 20th, it is predicted that in the next three days, most of the above-mentioned dry areas will still maintain high temperature and little rain, and the meteorological drought will continue to develop.

This year's continuous drought is the strongest high temperature and little rain weather since 196 1 has a complete record. According to the statistics of meteorological department, since July this year, the average number of days with high temperature above 35℃ in Zhejiang Province is 3 1 day, and the average number of days with high temperature above 38℃ is 16 days, which are the highest in the same period in history. For example, the average number of high temperature days in Chongqing has reached 29.3 days, the second highest in the same period since 195 1 year. For example, the number of high temperature days above 35℃ in Shanghai this year is 40 days, and the number of high temperature days above 40℃ is 6 days. According to the prediction of experts from the National Climate Center, this regional high temperature process will last more than 62 days in 20 13, making it the longest high temperature process since 196 1, and the comprehensive intensity of high temperature weather this year may be 196 1.

As the saying goes, plan ahead. In my opinion, in order to actively cope with extreme weather with high temperature and little rain, relevant departments should make corresponding emergency preparations for drought prevention.

First, dispatch all available water sources within the jurisdiction, giving priority to ensuring domestic water for urban and rural residents and drinking water for livestock. As the saying goes, water is the source of life. In my opinion, ensuring the safety of drinking water for people and livestock should be placed at the top of the current drought relief work. It is necessary to ensure the safety of drinking water for people and livestock under the current high temperature and little rain.

? ? The second is to strengthen drought monitoring and early warning, do a good job in water storage and conservation, and provide water source protection for drought relief. Strengthen drought monitoring and early warning and accurately control the development of drought; Strengthen the overall planning of water sources, formulate a scientific water supply plan according to the development of drought, ensure sufficient water for urban and rural people and livestock, and minimize the impact of drought on urban and rural residents' domestic water and livestock drinking water; Strengthen the dynamic management of water storage and water conservation, carry out artificial precipitation enhancement according to the actual drought needs, and increase the water storage capacity of drought-resistant water sources.

The third is to save water and limit unproductive high water consumption and service water. It is expected that the dry area will maintain high temperature and little rain in the next three days, and relevant departments should take measures to limit unproductive high water consumption and service water, giving priority to ensuring the domestic water demand of urban and rural residents and the drinking water demand of livestock.
