Jiangsu has carried out 11 artificial rainfall operations in many places. Did you rain there?

Jiaozhong News On August 16th, Xinhua Daily · Jiao Dian reporters learned from the meteorological disaster reduction department of Jiangsu Province that in order to effectively alleviate the drought, from the night of August 15th, Lianyungang, Suqian, Huai'an, Nanjing, Changzhou, Wuxi, etc. According to the needs of various localities (cities, districts) under the jurisdiction of the cities, and relevant local counties (cities, districts), they have seized the favorable weather situation to carry out artificial rainfall operations. As of the afternoon of August 16, there were 11 times in various places. Recently, according to the weather conditions, the meteorological department will also carry out artificial rainfall operations in a timely manner.

Artificial rainfall refers to the necessary conditions for artificially supplementing certain precipitation according to the principle of the formation of precipitation in nature, promoting the rapid condensation of cloud drops or touching and increasing into raindrops, and landing to the ground. The method is to choose the right time according to the physical characteristics of different cloud layers, and use aircraft and rockets to sow dry ice, silver iodide, salt powder and other catalysts in the clouds to make the cloud layer precipitation or increase precipitation Or water supply capacity, or increase the amount of water power generation.

For example, in the announcement of the artificial rain increase operation implemented in Nanjing, it was mentioned that this artificial rainfall operation was filed with the airspace control department, and Touqiao Village, Xinji Town, Liuhe District (118 ° 39′59 ″ E, 32 ° 17′28 ″ N ) The new site of the Meteorological Bureau of Pukou District (118 ° 24′58 ″ E, 32 ° 04′22 ″ n) is the operating point of the rain increase, and the operating point is the administrative area within 10 kilometers. The operation equipment use equipment is WR-98 special artificial rainfall rocket. The operation is dangerous. The safety alert scope of the operation site (within 50 meters from the rocket operating vehicle) is forbidden to watch.

The reporter can be seen from the on -site work photos sent by the provincial meteorological disaster reduction department that the rocket was launched through the car transmitted rack. To ensure safety, the wires and switching of the rocket's wire and switch distance have sufficient safety distance. "At present, the 11 rainfall operations have a certain catalytic effect. The cloud group that did not form precipitation was not formed to form a liquid precipitation process." Jiang Yifang, chief forecaster of Jiangsu Meteorological Observatory, told reporters that according to the forecast, there is a precipitation in the province today. In the process, the rocket rainfall work makes the precipitation effect more obvious.

The reporter noticed that at 3 pm, there were precipitation cloud groups in most parts of Jiangsu. Among them, there were strong waves in local areas such as Nanjing, Zhenjiang, Changzhou, Nantong, Suzhou, etc. In addition, Huai'an, Yancheng, Taizhou and other places also had obvious precipitation. Jiang Yifang said that this round of precipitation and artificial rain increase operation have achieved a more obvious cooling effect. On the 16th, the maximum temperature in more than half of the province dropped to below 35 ° C. The only highest temperature in Xilian Island (29.8 ° C) was not reached today Region at 30 ° C; at 3:02 pm, the Jiangsu Meteorological Observatory lifted a high -temperature orange warning signal.

"From the 16th to 17th, there are still obvious precipitation in the south and southern parts of Jianghuai. On the 18th, there are high temperature weather in the southern part of our province and most of the provinces on the 19th." Jiang Yifang said that on the 16th The temperature is about 34 ° C, the Huaibei area is 31-32 ° C, and the other regions are about 33 ° C. "Although we ushered in a short cooling, the highest temperature on the 18-23 will reach 37 ° C -40 ° C. Pay attention to heatstroke prevention and cooling." Jiang Yifang said.
