From 13:00 to 15:00 on May 5, Xiaohengshan District in Jixi City was experiencing a strong convective weather process under the background of low vortex circulation. This weather process was accompanied by thunderstorms and strong winds.
At the time of the incident, the area was affected by cold and warm air shear and topography, resulting in local cyclonic strong winds, which belonged to the weak tornado category.
The area affected this time is tens of meters to several kilometers, and the duration is several minutes to tens of minutes. This situation is difficult to be monitored by weather radars and automatic observation stations.
At present, my country has not yet launched tornado-related forecasting and early warning services, and there are still difficulties in monitoring and predicting weather phenomena such as tornadoes with a small scale and short life history.

In response to thunderstorms and strong winds in the area on the afternoon of May 5, the meteorological department issued warning signals for strong winds and thunder and lightning in a timely manner.
In response to this type of severe weather, the meteorological department will strengthen the construction of weather radar, ground monitoring and other equipment, and strive to improve the monitoring and early warning capabilities.
The general public should also strengthen the awareness and ability of such disaster weather avoidance.
