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.

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.

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.
