Lightning struck Hanoi due to strong thunderstorms.

On the morning of October 11, there were approximately more than 1,000 lightning strikes in Hanoi. Specifically, according to information from the technical department of Power Transmission Company 1, from 9am to 10am, Hanoi had 1,303 lightning strikes, of which 557 struck the ground.

Explaining the above phenomenon from a meteorological perspective, Director of the Northern Hydrometeorological Station Vo Van Hoa said that the main cause was strong thunderstorms that caused lightning strikes in Hanoi during the above period. On the other hand, this is the time of changing seasons so lightning strikes during thunderstorms have been common in recent times.

At the same time, at 7:30 am on October 11, the National Center for Hydro-Meteorological Forecasting issued a warning of thunderstorms, tornadoes, lightning, hail and heavy rain in the inner city of Hanoi. At the time of the announcement, the convective cloud area was developing strongly and causing thunderstorms in the areas of Chuyen My, Dai Xuyen, Ung Hoa (Hanoi). This cloud area continued to move and expand towards the inner city. Warning, in the thunderstorm there is a possibility of tornadoes, lightning and strong gusts of wind.

Providing more information about lightning strikes caused by thunderstorms, Dr. Truong Ba Kien, Deputy Director of the Center for Hydrometeorological Research, Institute of Hydrometeorology and Climate Change, Ministry of Agriculture and Environment, said that lightning strikes often occur during thunderstorms because of strong electrical polarization in thunderstorm clouds, creating a large electric potential field between the cloud and the ground. The continuous discharge process can cause lightning to appear repeatedly in the same location or in neighboring areas. The discharge of clouds and the discharge of clouds to the ground also creates lightning. In addition, the interaction between hot and humid air masses and cold air, along with the rapid formation of thunderstorm clouds, further increases the intensity of thunderstorms.
