the rain in beijing lasted from the night of september 19 to the morning of september 20, and many districts have issued rainstorm warnings. the rain was relatively heavy during the morning rush hour today (september 20), and there will be more rain clouds moving towards beijing, bringing rain.
focus 1: how heavy is the rain?
according to the meteorological department, from 23:00 on september 19 to 9:00 on september 20, the average precipitation in the city was 19.4 mm, and the average precipitation in the urban area was 31.9 mm. the maximum precipitation occurred in mentou village, haidian, at 93.6 mm. the maximum precipitation in the last hour occurred in shilou, fangshan, at 27.5 mm.
according to my country's rainfall standards, rainfall between 15.0-29.9 mm in 12 hours is heavy rain, rainfall between 30.0-69.9 mm in 12 hours is torrential rain, and rainfall between 70.0-139.9 mm in 12 hours is torrential rain.
it can be seen that as of 9:00 today (20th), the rainfall in beijing reached the heavy rain standard, the urban area reached the rainstorm standard, and heavy rainstorms occurred in mentou village, haidian.
focus 2: where does the rain fall the heaviest?
this morning, the beijing meteorological bureau broadcast live about the rain. reporters learned that this morning, the rainfall was most obvious in front of the western mountains.
yin zhaoyin, a weather analyst at the beijing meteorological service center, said the combined effects of wind and terrain led to heavy rainfall in front of the western mountains.
meteorological monitoring shows that there was a southeast wind at an altitude of 1,500 meters in beijing this morning, blowing from pinggu to the west. to the west of beijing is the taihang mountains. the southeast wind brought moisture from the bohai bay, and a large amount of moisture appeared just to the east of the taihang mountains, forming rainfall. this is the main reason why it rained heavily in haidian and shijingshan this morning.
focus 3: how long will the rain last?
after this wave of rain this morning, there will be rain clouds in the northwest of hebei, and the clouds will continue to move southeast, bringing rain to beijing.
yin zhaoyin said that the intensity of the next wave of rain will be significantly smaller, because the rainfall during the morning rush hour has basically released the unstable energy in the atmosphere. "the rain over beijing this morning was relatively rapid, and the unstable energy was released. so after this wave of rain passes over the taihang mountains and reaches the urban area of beijing, the rain will weaken."
it will take until around 5 or 6 this evening for the subsequent rain clouds to move out of beijing, which means the rain will gradually decrease, but it will take until at least 5 or 6 in the evening for the rain to stop completely. "this rain will affect the evening rush hour, but the rain is already very light during the evening rush hour," said yin zhaoyin.
the beijing meteorological observatory reminds that it will rain during the day today and the temperature will drop sharply. please pay attention to protect against wind and rain and add clothes to keep warm. the roads will be slippery on rainy days and visibility will be low in the morning. please drive carefully and pay attention to travel safety.
