From February 9 to 10, where did artificial precipitation increase in Guangdong?

From February 8th, Guangdong will have its first large-scale rainfall in 20021year. Scientific methods are needed to alleviate the drought through scientific water storage in this rainfall. The meteorological department of Guangdong province carried out artificial precipitation enhancement in many places in Guangdong from February 8 to February 10. By the afternoon of February 10, all the forest fire warning signals that had troubled Guangdong for a long time had disappeared. ?

1. Background of implementing large-scale artificial precipitation enhancement: According to the statistics of Guangdong Meteorological Department, since the end of June 65438+ 10 in 2020, the precipitation in Guangdong Province has obviously decreased, including June 65438+ 10 to February in 2026. Because there is no obvious rainfall for a long time, the storage capacity of large and medium-sized reservoirs in Guangdong is 20% less than normal, and there is a certain degree of water supply pressure in parts of eastern Guangdong and northern Guangdong. There is no obvious rainfall for a long time, and the fire risk is obviously improved. 202 1 Before the first large-scale rainfall, the forest fire risk level in Guangdong Province was on the high side, and the forest fire risk warning was issued in the * * *10/warning area. According to the previous forecast, there will be an obvious large-scale rainfall process in Guangdong before the 202 1 Spring Festival holiday. Combined with the weather forecast, Guangdong Weather Modification Center decided to implement artificial precipitation enhancement during the first large-scale rainfall in 20021.

2. In which areas did Guangdong carry out rainfall operations:

From 8: 00 on February 8 to 65: 08+03 on February 65, 438+03, artificial precipitation enhancement was carried out 52 times at 38 operating points in Shaoguan, Qingyuan, Meizhou, Yunfu, Zhaoqing, Maoming, Zhanjiang, Yangjiang, Huizhou, Jiangmen, Heyuan, Jieyang and Shanwei 13 cities, and 227 rockets were fired.

On February 9, 4 smoke stoves in Yangxi, Yangjiang operated for 3 times, 1 1 burning flame strips;

February 10, Shaoguan Nanxiong carried out air gun operation 1 time, and fired 364 catalytic substances.

Third, the effect after the implementation of rainfall operation:

Except? Ground to air? , the operation department still adopts? Air to air? Methods of artificial precipitation enhancement. From February 9 10 to February 9 13, Guangdong Meteorological Bureau organized Yun-12 aircraft to carry out precipitation enhancement operations for three times, and coordinated Jiangxi Weather Modification Center to arrange Kongwang aircraft to operate in northern Guangdong 1 time. Four sorties flew for 9 hours and 36 minutes, with a cumulative impact area of128,300 square kilometers. By the evening of February 10, the cloud system related to the rainfall before the 20021Spring Festival had gradually moved out of Guangzhou and continued to move eastward. The meteorological department predicts that the rainfall related to the cloud system in Guangdong Province is expected to gradually stop on or before New Year's Eve. It is estimated that during the Spring Festival holiday (from the first day to the sixth day), the weather in Guangdong is generally stable, with no strong cold air and heavy precipitation, mainly cloudy and warm weather.

Although artificial precipitation enhancement can improve rainfall potential, it also needs rainfall conditions to implement it. The meteorological department of Guangdong Province predicts that the rainfall in Guangdong will still be less than normal in the future, and the meteorological department will continue to monitor the weather changes and seize the favorable opportunity to continue to implement artificial precipitation enhancement operations; In addition to the scientific implementation of weather modification measures, the meteorological department also suggested that all parts of Guangdong can use water scientifically by raising awareness of water conservation.
