The drought in the next week without heavy rainfall in Guizhou will continue

The Guizhou Provincial Meteorological Observatory issued a forecast on the 9th, saying that there will be no large-scale heavy precipitation in Guizhou in the coming week, and the drought in the province will continue to be maintained or even developed.

Based on the comprehensive analysis of the latest meteorological data, Guizhou Meteorological Observatory has no extensive precipitation process in Guizhou in the coming week. It is estimated that from the 9th to the 11th, the whole province will be dominated by cloudy and cloudy weather with scattered showers. From the 12th to the 15th, the province will have sunny, hot, and rainy periods, except for scattered showers or thunderstorms in the western part of the province. The area is cloudy to sunny, and the eastern part has high temperature above 35 °C. Due to the high temperature and high evaporation, the drought conditions in various places will be re-developed on the original basis. It is recommended that all localities continue to do a good job in resisting major disasters, resisting drought and resisting drought.

From January to July this year, the total precipitation in Guizhou was 4 to 50% less than that in normal years, and in most of the regions in July, it was 5 to 10% less. According to the China Meteorological Administration, the precipitation in Guizhou in July was the lowest recorded in the same period in 1951. From mid-July to August 2, there were continuous hot and cold weather in most parts of Guizhou. From July 19 to August 2, the range of more than 50 counties (stations) above 30 °C was 12 days. The continuous high temperature and low rainfall climate has caused the water storage, river runoff and groundwater level in Guizhou to be affected to varying degrees. The available water sources in various places have been reduced, and the drought resistance has been weakened, which seriously affects agricultural production.

According to the Guizhou Provincial Disaster Reduction Committee and the Civil Affairs Department, as of August 4, 79 out of 88 counties (cities, districts) in Guizhou suffered from droughts, with a total affected population of more than 12 million people, due to drought of nearly 2.4 million people, 80 It is difficult for Wantou large livestock to drink water.

The nine cities and states carried out 315 rain enhancement operations, using 2,323 rounds and rockets 303. 4, 4 ground iodide generators were operated 4 times, and 3 times and 9 hours of aircraft artificial precipitation enhancement were carried out, which effectively increased the precipitation. Some of the reservoirs in Shantang Reservoir increased, soil moisture improved, and drought in some counties and cities. A certain degree of temporary mitigation plays a positive role.

According to the monitoring, at 8 o'clock on the 8th, the number of special drought-stricken counties in Guizhou Province dropped from 15 on the 3rd to 4, and from 18 in heavy drought counties to 12, but due to uneven distribution of precipitation, there are still some counties and cities. 10 mm, the drought continues to maintain and even develop.
