Bayan weather

Bayan county, Harbin is suspected to have been hit by a magnitude 7 tornado, and the scene is chaotic!

Life newspaper, June 7 th, 5 th, an article "There will be a hail tornado in Harbin in the future 10 days!" The article was madly transmitted in the WeChat circle of friends, which shocked many small partners. The reporter asked the Harbin Meteorological Observatory for verification. The staff said that the topic of this WeChat was taken out of context. If you read the article carefully, you will find that tornadoes and hail are actually only one kind of strong convective weather, and there is less possibility of tornadoes in Harbin.

Statistics show that from 7: 00 on June 18 to 7: 00 on June 19, there were heavy rains at 7 stations in Heilongjiang, all of which were concentrated in Mudanjiang area, and 33 stations had heavy rains, reaching the intensity of heavy rains. Affected by precipitation, urban waterlogging occurred in some areas of Mudanjiang.

Cyclone is a form in which a small part of the huge energy of thunderstorm is released in a small area. The surface temperature rises rapidly in summer, and the convection is active from afternoon to evening. In addition, the vast plains in Northeast China provide a favorable environment for the occurrence of tornadoes.

The staff of the Meteorological Observatory said that the content in this WeChat was indeed released by the Harbin Meteorological Observatory: affected by the northeast cold vortex, it is expected that there will be short-term heavy precipitation, hail, lightning, short-term strong winds, tornadoes and other strong convective weather in various districts and counties (cities) of Harbin from May to June. However, the title of WeChat unilaterally extracts the content of the article, ranking last and most unlikely? Tornado? On the title, an exclamation point was added. Obviously, the title party is for the attention of bloggers. According to the reporter, there have been tornadoes in Shuangcheng, Bayan and Zhaoyuan Songhua River in Harbin history. However, one of the conditions for the formation of tornadoes is moderate cold and warm convergence airflow, and the other is a large area of flat land or water surface, or with the help of plateau mountains, canyons and other topography. Therefore, at present, there is little possibility of a tornado in Harbin.

According to the Harbin Meteorological Observatory, there was heavy rain during the day from the night of the 6th to the 7th, moderate to heavy rain in all districts and counties (cities) of Harbin, and heavy rain in some towns and villages of Bayan, Mulan and Tonghe in the north. 9 ~ 10 cloudy with showers or thunderstorms; 1 1 ~ 13 There was a moderate rain, and there was heavy rain locally.

The staff of Harbin Meteorological Observatory advised citizens to take more clothes to prevent colds. At the same time, relevant departments should do a good job in urban drainage, and strengthen billboards, temporary structures and other facilities in windy days.

Affected by the tornado, the county 13 high-voltage power lines and 94 transformers tripped and stopped, affecting nearly 10,000 people's electricity consumption. After the disaster, the county electric power department sent nine teams of more than 200 people to repair overnight. ?

At that time, it rained heavily. Later, I saw a strong wind blowing from south to north at random. The sky is covered with plastic bags and colored steel tiles. The wind doesn't last long, only 10 seconds to 20 seconds, and it becomes smaller when there are few buildings. ? Dawei, a vendor from Yuliangbao, happened to drive by Bayan County in Harbin and saw this thrilling scene.
