How is strong convection formed? How to escape when there is a tornado?

Strong convective weather is the accumulation of more water vapor on the ground. Because the specific gravity of water vapor is lighter than that of air, the specific gravity of hot and humid air mixed with air will be lighter than that of air, and the hot and humid air will float up to form a rising hot and humid airflow. When it rises to a certain height, due to the temperature drop, water vapor will condense into small water droplets to form clouds. At this time, its volume will soon be reduced to11244 of the original volume, forming a low pressure area. At this time, the area will attract air from all directions to supplement. Due to constant attraction, the hot and humid air on the ground will rotate and rise. Due to the centripetal force of rotating air, it will more strongly attract the cold air above and the hot and humid air below to meet, thus forming.

It is precisely because of the low pressure caused by the shrinking water vapor volume that there will be strong convective movement of the atmosphere, accompanied by the formation of various disastrous weather such as thunderstorms, strong winds, hail, tornadoes and local heavy rainfall.

It is dangerous to encounter a tornado, so we must actively find ways to avoid it, and don't panic.

1. When you encounter a tornado in the wild, remember to run fast, but don't run around. You should run away as fast as possible in the direction perpendicular to the tornado route. Those who have no time to escape should quickly find a low-lying place to get down. The correct posture is: face down, close your mouth and eyes, and protect your head with hands and arms.

2. When encountering a tornado, be sure to stay away from trees, telephone poles, simple houses, etc. To avoid being smashed, crushed or electrocuted.

3. In case of emergency when telephone poles or houses collapse, cut off the power supply as much as possible to prevent electric shock or fire. & gt

4. The safest place to avoid tornadoes is the basement or semi-basement of concrete buildings, and simple houses is very unsafe. Note: Never stay on the roof.

If people are indoors, avoid windows, doors and external walls of houses, and hide in the small room opposite the tornado and squat down. At the same time, cover your body with a thick mattress or blanket to prevent you from being hurt by falling things.
