Dongming County, located in the southeastern part of Shandong Province, is in the hinterland of the Huanghuaihai Plain and is a typical temperate monsoon climate zone.
Such geographical location and climatic conditions cause Dongming County to often suffer from severe convective weather at the turn of spring and summer, especially when warm and humid air currents meet cold air here, which can easily cause drastic meteorological changes.
At around 15:00 on April 27, a sudden tornado struck Dongming County, resulting in one death and 79 injuries.
Behind this natural disaster is the result of the interaction of a series of complex meteorological processes.
According to the analysis of the China Meteorological Administration, the cause of this tornado is mainly related to the following factors: First, the recent continuous strengthening of the warm and humid air flow in the southwest of the South China Sea has transported a large amount of water vapor and energy to Dongming; second, the local atmosphere has been in an unstable state of high temperature and high humidity for a long time, and a large amount of unstable energy has gathered near the ground; third, the strengthening of the low-level jet stream has intensified the unstable stratification of "cold above and warm below"; fourth, the passage of mesoscale convergence lines on the ground and high-altitude fluctuations serve as triggering conditions, triggering strong updrafts, which caused the parent storm of the tornado to develop strongly.
As an extreme meteorological phenomenon, tornadoes are extremely destructive and can cause huge material losses and casualties in a very short period of time.
Its formation requires specific meteorological conditions, including strong updrafts, large amounts of water vapor and a specific atmospheric structure.
In the Dongming County incident, the above conditions were unfortunately met, leading to the tragedy.
In the face of such severe natural disasters, it is particularly important to raise the public's awareness of disaster prevention and mitigation.
First of all, residents should pay attention to weather forecasts and take protective measures immediately if they receive warning information about severe convective weather.
Secondly, it is also necessary to understand some basic risk avoidance knowledge. For example, when encountering a tornado in the wild, you should flee in the direction perpendicular to its movement; if the situation is urgent, you should quickly find a low-lying area and lie down, away from large trees, telephone poles, billboards, walls, etc.
If you encounter a tornado while driving, you should drive in the opposite direction to avoid it; if the distance is very close, do not try to continue driving, but quickly abandon the car and take shelter in a low-lying area.
If you encounter a tornado at home, you should avoid windows, doors, and the exterior walls of the house, go to a room opposite the direction of the tornado, squat with your head covered, and it will be safer to hide in a concrete building.
Through these practical actions, we can reduce the losses caused by natural disasters to a certain extent and protect people’s lives and property.
At the same time, this also reminds us that respecting and revering nature is the prerequisite for human survival and development.
Only by continuously improving our understanding of and ability to prevent natural disasters can we be more calm in the face of challenges from nature.
