Huai'an, Jiangsu: 12 days in a row to "smoke", manually increase rainfall to cool down

For 12 consecutive days, high temperature orange warning every day, the highest temperature went straight to 37 ° C, became a commonplace. Recently, the high temperature and hot summer weather seemed to be a copper wall and iron wall composed of heat waves. It was not until the 16th. Tone. What many people don't know is that there is also the credit of artificial "assistance" behind this wave of rainfall. According to experts from Huaian Meteorological Observatory, from the current latest weather data, high temperatures have not completely left, and they may recalculate back and after the 18th to remind everyone to continue to do a good job in heatstroke and cooling.

The reporter learned from the Huaian Meteorological Bureau that in order to effectively alleviate the drought caused by the sun and hot rain in the past few days, in accordance with the requirements of the municipal government and the application of relevant county and district governments, the Huai'an Meteorological Bureau conducted operations in six counties and districts in the city. Essence According to the approval of the air management department and weather conditions, at 1:30 on August 16th in Yumeou Town, Huaiyin District, 1:59, Liaosu Town, Liaoshui County, Malang Village, Liaoshui County, 2:45, Huai'an District, Huai'an District, Huai'an District, Huai'an District Divided into Shunhe Town of Zezawa and 11:58, Gu Sang Street, and carried out artificial rain increase operations. The operating area and operation area influenced the rainfall, and a certain effect was achieved. As of 14:00 on the 16th, Huai Safe City has 1 site with a site of more than 100 mm, 5 stations above 50 mm, 21 stations above 25 mm, and a maximum precipitation of 103.9 mm.

Perform manual rainfall operations at night

In addition to alleviating drought, rainfall is also obvious in relieving high temperature. So why can we not perform a wave of manual rainfall operations when the early high temperature continues? According to the staff of the office department of the Huaian Meteorological Bureau, many citizens called in the early stage to express similar needs. In this regard, Geng Jianwu, a senior engineer of the Service and Social Management Office of the Huai'an Meteorological Bureau, said that artificial rain increase operations do not want to carry out. First, we must meet the needs of local economic development. It is particularly important to have objective weather conditions that can carry out artificial rainfall operations. "Artificial rainfall is not artificial rainfall. At present, there is no way to change the rain in the air. We can only manually trigger the natural rainfall mechanism based on the full study of the process of understanding the natural precipitation process." Successfully implementing artificial rainfall operations, there must be clouds over the work location, but not all clouds have precipitation potential. Only those clouds with thick clouds, rich water content, and insufficient natural precipitation, through artificially sow iodine, silver, dry ice, dry ice, dry ice, dry ice, dry ice, dry ice, dry ice Only catalysts such as salt powder can cause the cloud layer to produce precipitation or increase precipitation. At present, the main methods of artificial sowing catalysts are aircraft, rockets, or high guns. Generally speaking, the rain increase operation of stable layered clouds in the spring and autumn seasons is easier to succeed. In summer, due to the unstable weather system, the conditions are not difficult to implement. The location and time of artificial rainfall operations are not free to choose. In order to ensure safety, the rockets and shells of artificial rain increases should be far from town and villages. The department applies for the operation airspace and strictly carries out within the approved airspace time. Geng Jianwu said that in the later period, if the meteorological conditions permit, the municipal meteorological department will also choose to carry out artificial rainfall operations.

How hot is this summer? A recent statistics of the Huaian Meteorological Observatory gave the answer. Since the summer, Huai'an has appeared in three rounds of high-temperature weather (June 16-19, July 8-15, and August 2). From June 1st-August 14th, the city's average temperature was 28.8 ° C, which was 2.6 ° C higher than the same period of the year, the highest in the same period since 1961. High temperature (daily maximum temperature ≥35 ° C) daily 21 (Huai'an) ~ 30 (Huai'an District). The city's average high temperature number is 25 days, the most during the same period since 1961. From June 1st-August 14th, the city's average precipitation was 266.0 mm, which was 189.2 mm less than the same period of the same year, and 4.2 % less. It is understood that on the 15th, the two meteorological observation stations in Huai'an District and Jinhu County were measured at the highest temperature of 38.5 ° C and 39.2 ° C, respectively, and each broke the historical highest record left in 2017. Tang Jie, deputy director of the Huaian Meteorological Observatory, introduced that from the value of meteorological records, the highest temperature in Huai'an City recently is lower than other areas in the province. The impact of the effect, the actual temperature of the Huai'an urban area is actually higher than the value of the record. Judging from the latest weather data, from the 18th to 22nd, it is expected that the weather in Huai'an will be based on cloud systems. In the afternoon, thunder showers will return to the highest temperature. The good news is that starting on the 23rd, the round of high temperature in front of the eyes is expected to come to an end. Since then, it may not be ruled out that the high temperature may appear, but the duration should not be so long.

The following is the recent specific forecast:

It is cloudy on August 17th, from northeast to Dongfeng 3 to 4,

Minimum temperature: 25 ° C to 26 ° C, the highest temperature: about 33 ° C.

There are clouds on August 18. There will be shower or thunderstorms in the local area in the afternoon.

Minimum temperature: about 25 ° C; maximum temperature: about 35 ° C.

On August 19th, there are clouds to overcast, and some areas have shower or thunderstorms.

Minimum temperature: 28 ° C to 29 ° C; maximum temperature: about 38 ° C.Rong Media reporter Fu stopped
