Monitor precision forecasting precision service Fine Hunan Meteorological Department to deal with rare high temperature and drought in history

In the past few days, many Hunan people are looking forward to waiting for a cooling weather. In the early morning of August 24th, as forecast, Changsha, which has been hot for a long time, ushered in the breeze, and it did not seem to be roasted in the sun.

In response to this cooling weather, the meteorological department of Hunan Province deployed in advance, precision monitoring, precision forecast, and fine services. Not only that, since the flood season, Hunan has abnormal weather and climate, and the rainfall presents the characteristics of "more and less"; after the rainy season on July 8th, the province's precipitation is abnormal, the high -temperature heat wave duration, wide range, strong extreme, meteorological weather, meteorological weather The drought development is fast and heavy. During the flood, the weather and climate trend is like forecasting and forecasting, which is almost the same.

Since July 8th, there is a rare continuous sunny and hot weather in Hunan. The average temperature of the province is 30.9 ° C, which is 2.5 ° C higher than the same period of the year. , 74.7%less than one year, ranking 1st low in history since 1961. As of now (August 22), 100 counties and cities in the province have reached the level or above, and the scope of influence accounts for 95.9%of the province's total area of ​​95.9% Essence

In order to cope with high temperature and drought weather, the Provincial Oncenticine Administration conscientiously implemented the requirements of the provincial party committee and provincial government's drought -resistant and drought -resistant work decision -making deployment and the instructions of the provincial leaders, adhered to the flood prevention and drought -resistant hands, and made every effort to do a good job of high temperature drought and disaster prevention and mitigation services.

The first is to strengthen departmental consultations and provide a scientific basis for scientific dispatching rain and flood resources. In March, the Hunan Provincial Climate Center made a trend of "less before rainfall, less drought before waterlogging, obvious regional and staged characteristics of drought and flooding, and accurately predicts the end of the end of the rainy season. While ensuring the safety of the flood, stop the tail water from July 2nd to 5th, the tailing of the Typhoon Siam, and the water storage level is as much as possible. In addition, actively do a good job of drought -proof and drought -resistant work with the federations of emergency, agriculture, electricity and other departments.

The second is to do a good job of early warning and early warning of high temperature drought monitoring. Since July 22, four special special deployment of drought -resistant meteorological services has been deployed four times. On August 1st and 15th, two issues of "Major Meteorological Information" were released, emphasizing that "August is mainly based on sunny heat and high temperature, beware of the rapid development of meteorological drought", rolling release of "Meteorological Report" and "Meteorological Information Express" 15 In the period, the high -temperature warning 91 and the early warning signal of 833 were 30.69 million, and on August 14th, the province's first meteorological and arid provincial yellow warning was released this year.

The third is to actively prepare for artificial rainfall operations. From late March to mid -July, the annual inspection of the province's high guns and rocket installations, completing the airspace coordination with the southern theater, the western theater, and the central theater. Entering August, all cities and counties in the province have done a good job Preparation. On August 10th, the western theater dispatched rainfall aircraft to arrive in Changsha, and the aircraft rain increase equipment debugging and test flight was completed from 12th to 15th.

The fourth is to seize the favorable weather conditions and actively increase rainfall operations. The local time has seized the rain increase operations from July 17th to 20th, 27th to 30th. There were 198 ground operations in 71 counties and cities in 14 cities in the province, with a cumulative area of ​​27,000 square kilometers and an increase of about 80 million tons of rainfall.

The Hunan Meteorological Observatory predicts that from the 24th to 25th, due to the influence of the cloud system of the "saddle" typhoon, there will be a cooling and rainfall weather in most parts of the province. Among them, the high temperature in Xiangbei was slightly relieved on the 24th; from the 25th to 29th, the high temperature developed again; at the end of August, the process of cooling and rainfall in the province will gradually relieve the high temperature.

In the next step, the meteorological department of Hunan Province will strengthen meteorological monitoring and early warnings, permit a fine medium and long -term weather forecasting, and to discuss and judge closely with emergency, water conservancy, agriculture and other departments to do a good job of drought -proof and drought and drought. In addition, the ground operating equipment staff and rainfall aircraft of the meteorological departments in various places are ready. It will focus on the favorable weather on the 24th to early September, organize aircraft and ground three -dimensional artificial rainfall operations to maximize the increase of rainfall.
