Downs the "6 Ankang Reservoir" water in a week?An important weather report in Shaanxi Meteorology!

On July 17, the reporter learned from the Shaanxi Provincial Meteorological Bureau that from July 10th to 16th, the two heavy rainfall arrived as scheduled. Shaanxi Province's precipitation was equivalent to the volume of 6 Ankang Reservoir! In this process, the meteorological department seized the situation of favorable weather, scientifically carried out artificially hail and rainfall operations scientifically in terms of regions and time periods, and effectively utilized cloud water resources.

So, how much is this Gan Lin "quenching thirst"?

Hu Lin, chief of service at the Shaanxi Provincial Climate Center, introduced that from May to early July, Shaanxi experienced continuous drought. In the past two months, although Shaanxi has gone through the process of precipitation, the distribution is unevenly distributed, and the local precipitation has a small magnitude, which has led to the rise of the drought and the situation of the underworld. Earlier, the meteorological department has prepared for rain increase operations and is only favorable for the weather process.

In mid -July, Shaanxi ushered in two heavy precipitation process. Seize the situation of favorable weather, a scientific and efficient "hydrating action" quickly expands: 12:00 on July 10th to 12:00 on July 10th, 21 districts and counties such as Xi'an, Tongchuan, Baoji and other 8 districts and counties will launch ground artificial hail and rainfall rain and rain. Operations, the operation area is 4274 square kilometers; from 0:00 on July 14 to 10:00 on the 16th, 11 districts and counties in Xi'an, Shangluo, Yan'an, and Hanzhong to carry out ground artificial hail and rain and rain and rain. Essence Under the action of natural and artificial rainfall, the two rainfall process produced a total of 15.646 billion tons of precipitation, which is equivalent to the volume of 6 Ankang Reservoir.

Li Yanli, director of the Agricultural Meteorological Room of Agricultural Remote and Economic Crop Meteorological Service Center in Shaanxi Province, introduced that two large -scale heavy precipitation weather is very favorable for rapid recovery of corn, soybeans, potatoes and other autumn grains. Fruit expansion weight gain.

Monitoring shows that on July 14, soil affairs in most parts of Shaanxi began to improve. Among them, the relative humidity of soils in northern Shaanxi, western and southern Guan and southeast, northwestern Shaanxi, and southwestern southwestern southwestern were appropriate. On the 16th, the droughts of most of the weather in northern Shaanxi and Guanzhong have been lifted. At the same time, after the two strong precipitation, the water levels of the main reservoirs in Shaanxi have increased to varying degrees. Take the water level of Shimenxia, ​​Shimen, Xi'an, and Shimen Reservoir in Hanzhong as an example. Water level.

Shaanxi is one of the most scarce provinces in the country, and the distribution of water resources is uneven, and 71%are concentrated in southern Shaanxi. Due to the three climate bands, the time and space distribution of local natural precipitation is also uneven. Carry out the divided area, time period, and targeted refined artificial rainfall operations. It can make full use of cloud and water resources to better meet the needs of industrial and agricultural production, water source cultivation, and ecological protection.

On the other hand, under the influence of two rounds of rainfall, some rivers in Shaanxi have appeared in flood conditions. The Shaanxi Meteorological Observatory released important weather reports at 11:30 on July 17. Affected by the Western West Tank and the low vortex, most of Shaanxi will have an obvious precipitation process from the 18th to 19th. Meteorological experts remind that the public should pay attention to the weather forecast and early warning information in a timely manner, and try to avoid areas with high risk of meteorological disasters such as mountainous areas such as rainy days to do a good safety protection.

18-19 in central and southern Shaanxi, there is a strong precipitation in the south of Shaanxi

At 11:30 on July 17, the Shaanxi Provincial Meteorological Observatory issued an important weather report: Affected by the Western Wind Sinks and the low vortex, most of the provinces will have an obvious precipitation process from the 18th to 19th. The main precipitation period is on the night of the 18th During the day on the 19th, it is expected that there will be small rain in southern Shaanxi and northern Guanzhong. Essence Southern Shaanxi focuses on the rapid drought and flooding, and the effect of preventing heavy rain areas in the southern part of Guanzhong

The process is a mixed precipitation. The process is accompanied by short -term rainstorms in the early stage. It is expected that the maximum hourly rain is 20-40 mm, and the local area can reach more than 50 mm. Cumulative precipitation: 25-60 mm in southern Guanzhong and northern Shaanxi, 40-80 mm in southern southern Shaanxi, and 80 to 110 mm in Qinba Mountain areas. In addition, on the central and eastern part of Shaanxi on 17-18, there is a high temperature above 35 ° C. The maximum temperature in some places in the health can reach more than 38 ° C. Around the 22nd on the 22nd period, due to the influence of the Western wind tank, there was still a clear process of precipitation in the province.

On 18-19, precipitation weather is conducive to alleviating high temperature and drought in southern Shaanxi, and is beneficial to the growth of crops. The drought and flood in southern Shaanxi turned sharply, and the Guan Middle Eastern South Tribe area overlapped with the early storm area. It is necessary to prevent secondary disasters such as floods, geological disasters and small and medium rivers, and urban and rural floods that may cause strong rainfall. Strong winds such as strong winds are harmful to the weather. This rainfall is conducive to alleviating the high temperature and drought in the early Shaanxi and southern Shaanxi. The drought area seized a favorable opportunity and carried out water storage and sacrifice in advance. It is recommended that the public pay close attention to the weather forecast, reduce or avoid going out during the period of heavy downshift to ensure personal safety.
