To "quench thirst", Jiangsu has carried out artificial rainfall in many places

Continuous high temperature, Jiangsu appeared in many places. The reporter 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 and other cities in our province, as well as relevant counties (cities, districts) Meteorological Bureau According to the needs of various localities, grasping the situation of favorable weather to carry out artificial rainfall operations. As of the afternoon of August 16, there were 11 assignments in various places. Affected by rainfall, the high temperature in the province will press the "pause keys" today, but the high temperature weather will return again tomorrow.

Why do you have no rain before, and the sky is lacking in rain.

Jiangsu High -temperature warning has been issued for 15 days. At 15:02 pm on the 16th, the Jiangsu Meteorological Observatory finally lifted the high -temperature orange warning signal. At 14 o'clock, Jiangsu was affected by precipitation. Decreased, the maximum temperature in more than half of the region dropped below 35 ° C. Among them, Nantong Tongzhou declined to a maximum of 13.7 ° C. The precipitation interrupted the recent continuous high temperature weather. It is expected that Jiangsu will finally withdraw from the high temperature "group chat" on the 17th.

Recently, the temperature in Jiangsu has been high, and friends often ask, why can't it be able to increase rainfall and cool down? In fact, because the air is lacking in the cloud that can catalyze the rain.

Artificial "rainfall" is not "rainfall", and it can only increase the probability and intensity of rainfall. In simple terms, three conditions require artificial rainfall: one is that the thickness of the clouds must reach 2 to 3 kilometers, and the other is that the water vapor in the clouds must be abundant, and the third is to have a rising airflow. Although it has continued to high temperature and drought in the near future, everyone is looking forward to rainfall manually, but at this time, the meteorological conditions are not available.

The implementation of rain increase is mainly to alleviate drought

The reporter was informed that as of 3:30 pm yesterday, Jiangsu has seized many places in Jiangsu to carry out artificial rainfall operations. Recently, according to weather conditions, the meteorological departments will also carry out manual rainfall operations in a timely manner. The meteorological department stated that the manual rainfall was mainly to alleviate the drought, which had little effect on changing the high temperature weather in the later period.

The meteorological department specially reminds that the operation is dangerous. Unrelated personnel are strictly prohibited from entering the range of 100 meters in the operation point, and onlookers are strictly prohibited. If an unsteady rocket or rocket bounces in the operating area, please report to the Meteorological Bureau or the local public security organs immediately, and it is strictly forbidden to deal with it without permission. If the rocket's residual body is found, please avoid avoiding it.

According to the forecast of the Provincial Meteorological Observatory, there are still obvious precipitation in the southern and southern parts of Jianghuai from the night of the 16th to the 17th, and the local area is so large that we remember carrying an umbrella. The lowest temperature in the next two days will also be more comfortable, and it is expected to fall below 28 ° C. On the 17th, the highest temperature in the province will be below 35 ° C. However, on the 18th, the southern parts of our province and most of the province's high temperature weather will return again on the 19th. Everyone pays attention to heatstroke and sunscreen.

In Nanjing area, as of 16:00, Nanjing Station's highest temperature is 36.7 ° C. According to the latest weather data analysis, under the influence of the cold and cold air flow, yesterday night to this morning, there are still precipitation in parts of Nanjing. It will be reduced to 33 ° C to 34 ° C, and the maximum temperature in Nanjing will reach 40 ° C again the day after tomorrow.

Use the "furnace" to rain artificially, have you seen it?

On August 16, the whole Nanjing was looking forward to a rain, but due to the south of the intersection of the cold and cold air, only the southern water in Nanjing and Jiang Ning were more "favored" by rain. As of 16:00, Nanjing's largest rainfall reached 47.6 mm and appeared in Dongping Street Station in Laishui District. When the rain was rained, the temperature dropped significantly, and the water station at 15:00 was only 25.5 ° C.

And this rainy rain yesterday also contributed to the local meteorological department. The reporter learned that the smoke furnaces were carried out by the Shuishui District yesterday afternoon from yesterday afternoon to the evening. Wang Kai, the director of the Meteorological Taiwan Meteorological Taiwan in Nanjing, told reporters that on the 16th, the Meteorological Bureau of Lishui District implemented three artificial rain increase operations at 13:14, 14:26, and 18:58 according to the weather. Smoke bars.

A device with a stove, with a pipeline at the upper end, about 3 meters high. Langshui built two new sets of long -range remote controls to artificially affect the weather on the ground flame stove to spread the system last year. By burning the cigarette strips, follow the ascending airflow into the clouds to achieve the purpose of rain. Compared with conventional artificial rainfall rockets, the ground smoke furnace has the advantages of low operating costs, remote control, low hazard coefficients, and non -airspace restrictions.

Data map

The reporter learned that, according to the physical characteristics of different clouds, the meteorological department will also choose the right time, and use aircraft, rockets and other forms to sow the clouds in the clouds, silver iodide, salt powder and other catalysts to make the cloud layer precipitation or increase precipitation. At present, it is adopted in many places. It also fired the rocket to rain. The reporter can be seen from the on -site work photos sent by the provincial meteorological disaster reduction department that Wuxi and other places will fire rainfall rockets through the car transmitting rack.
