What is extreme weather? How to save yourself when encountering extreme weather outdoors?

Extreme weather and climate events can generally be divided into extreme high temperature, extreme low temperature, extreme drought, extreme precipitation, etc., which are generally characterized by low probability of occurrence and great social impact. From the perspective of probability theory, if the temperature in a certain area or place is normally distributed under the average condition for many years, the probability of weather is the highest, the probability of hot and cold weather is small, and the probability of extremely cold or hot weather is even smaller.

Due to the influence of global warming, the average temperature in this area will rise, and the probability of high temperature weather will increase obviously. Extremely hot weather, which was rarely seen before, may appear frequently now, and extreme events such as high temperature and heat wave will become frequent. If the variance of temperature changes increases, extreme weather will occur more frequently.

There are always signs before danger comes. Earthquake is the earliest signal of tsunami, and there is a time difference from earthquake to tsunami, so we should use the time difference to avoid danger and escape. If you find that the tide fluctuates suddenly and abnormally, the sea level drops obviously or there are huge waves coming, you should evacuate quickly. On the one hand, try not to go to undeveloped scenic spots, don't take the undeveloped road of developing scenic spots, and don't do your best. On the other hand, before the flash floods hit, it was not without warning. Because mountain torrents come, they will carry branches, stones and other sundries, so the water flow will become very turbid. When the water in the mountain becomes turbid, tourists should immediately be vigilant and quickly evacuate to high places.

When driving in foggy days, immediately turn on the low beam, tail light, front and rear fog lights and double flashing lights. When the visibility is less than 20 meters, you must slow down, keep enough braking distance from the car in front, and find a suitable place to stop and wait nearby. Adjust the travel route in time, do not take risks or chances, do a good job of protection, and strive to return safely as soon as possible.

There are still many human factors leading to extreme weather events, and human understanding of extreme weather needs further scientific exploration. However, for human beings, there is only one earth. Before we fully understand the truth, we should strengthen self-restraint, reduce pollutant emissions, protect nature and be kind to the earth.
