The water in Longquan, Chengdu is serious. Why is it raining heavily this year?

In July and August this year, heavy rains hit all parts of the country, especially Sichuan. Traffic, tourism economy and people's daily life have been greatly affected, especially in Longquanyi District. The orange rainstorm warning signal issued by Longquanyi Meteorological Observatory from 08: 00 to 06: 53 on June/KOOC-0/6 was updated to rainstorm red warning signal: from 20: 00 on August/KOOC-0/5 to 07: 00 on August/KOOC-0/6, the maximum precipitation in this area occurred in Hong 'an Datong/KOOC-0/2/KOOC-0/mm for one hour. It is estimated that the rainfall in some places will still be above 100 mm in the next three hours, and it is necessary to strengthen the prevention of adverse effects caused by strong convective weather such as short-term heavy precipitation, lightning and short-term strong wind.

In the face of this extreme weather this year, some experts have analyzed that the main reason is that the western Pacific subtropical high system has strengthened its westward extension, the strong southerly warm and humid airflow has been re-established, and a steady stream of water vapor has gathered in the western Sichuan Basin, forming heavy rainfall; At the same time, the western Pacific subtropical high stagnated and did not move much, which made the favorable conditions for this heavy rainfall last for a long time and eventually caused heavy rains in Chengdu and some places. Moderate rain, from west to moderate rain to heavy rain, heavy rain in some places.

For this netizen, this time it happened because of heavy rain? Typhoon? Spiral cloud system is not affected by typhoon, but develops itself in Sichuan basin. The rain was not affected by the typhoon, but the shape of the rain cloud system was a bit like that of the typhoon cloud system.

Finally, I would like to remind you that the rainfall lasts for a long time, with heavy rainfall, highly saturated soil and high risk of geological disasters, so it is necessary to guard against geological disasters such as collapse and landslide. Pay attention to taking measures to reduce the impact of short-term heavy rainfall on urban low-lying areas, tunnels under construction and other projects under construction. Pay attention to the adverse effects of lightning, strong winds and heavy rainfall on transportation, tourism, agriculture and other industries.
