On April 12, according to the meteorological and emergency management departments in various places, strong convective weather occurred in Sichuan, Hebei, Chongqing, Hubei and other places on the mainland, suffering from high winds, hail and other disasters, of which Hangzhou, Nanchang, Chongqing, Shijiazhuang and other places cooled down by 12-14 °C
Sichuan Anyue suffered the strongest local wind since 1951, with a maximum wind speed of 13, which is a rare strong convective weather in recent years.

According to the public information of the Zhejiang Meteorological Bureau, strong convective weather is a sudden, rapidly moving, violent weather and extremely destructive weather referred to in meteorology, mainly thunderstorms and strong winds, hail, tornadoes, local heavy rainfall and so on. When strong convective weather comes, it is often accompanied by bad weather such as lightning and thunder, wind and rain, resulting in the destruction of houses, the destruction of crops and trees, the damage of telecommunications traffic, and even the cause of casualties.
In this regard, Zhang Juan, a meteorological analyst at the China Weather Network, introduced that the cause of this round of strong convective weather is due to the fact that most of the mainland in the early stage is dominated by warm air, the temperature has risen sharply, many places are unusually warmer than the same period of the year, when the cold air arrives, the energy accumulated in the atmosphere is stimulated, and this time the cold and warm air belongs to the strong and strong collision, both of which are not willing to show weakness, so it will stimulate a wide range of strong convective weather.
If the road encounters disasters caused by strong convective weather, it is necessary to deal with them:
Strong winds: try not to ride out, when walking near the construction site, you should try to stay away from the construction site and pass quickly, do not stay under tall buildings and billboards, and be careful of falling objects. Parking should be kept away from buildings, dead trees, and billboards. When driving through special terrain such as bridges, hold the steering wheel tightly and avoid crosswinds.
Flood: If the flood enters the house, the electric gate should be pulled off first. Follow the predetermined route to the slopes, highlands, etc. If surrounded by floods, use boats, wooden rows, door panels, etc. to transfer, if it is too late to transfer, climb the roof, trees, high walls, etc. to temporarily avoid danger, wait for rescue, do not swim by yourself to transfer. If you find a high-voltage line tower tipping, low-hanging or broken wires, stay away to prevent electric shock.
Landslide: Quickly evacuate to a safe shelter, and choose to be outside the boundary on both sides of the landslide. When encountering landslides, run in the direction of perpendicular to the rolling stones, and hide under solid obstacles when you can't run. In the event of a landslide, when you can not continue to escape, you should quickly hold the trees around you and other fixed objects, you can avoid under the strong obstacles, or crouch in the ground, ditch, you should pay attention to protect the head, you can use the clothes around you to wrap the head.
Mudslide: Observe the direction of the mudslide, do not run in the direction where the mudslide may pour, do not hide in trees and buildings, do not stay on the slope of soft soil and unstable soil, so as not to unbalance the slope and slide, and should stay in a stable place from the base. Take shelter on both sides of the direction of the mudslide, avoiding the curved banks of the river (ditch) or the narrow, low-height convex cliffs.
The Central Meteorological Observatory prompts that the strong convective weather is unpredictable, the destructive force is strong, the best defense is to dodge in time, once the meteorological station issued a strong convection related warning, should be in accordance with the requirements of the early warning, take corresponding preventive measures, must not be taken lightly.
