Thunderstorms and thunderstorms usually start with the development of small cumulus clouds and then develop rapidly. After a period of intense cumulus clouds and a mature cumulonimbus stage, it is a fierce, harsh and drastically changing weather. Field personnel should note the following: 1) Thunderstorms may occur when cumulus clouds begin to accumulate and turn black. 2) Thunderstorms usually last for a short period of time. To stay calm, don't be afraid to stay away.
The danger of lightning and lightning is the breakdown of objects and the human body, causing a fire, and the thunder generated by the human ear's eardrum. So it should be remembered:
1) Cars are often excellent lightning protection facilities and can be hid in cars.
2) The best places for protection are caves, ditches, canyons, or gaps under tall tall trees.
3) If you are in the open air, you should leave twice the height of the isolated tree.
4) When you feel the charge, that is, the hair is upright, or the skin is trembling, it is very likely that you have received an electric shock and you should immediately fall to the ground and protect yourself.
5) If evasive in the vicinity of isolated projections, the top of the projection should be at least 15-20 meters higher than the head.
6) Leave vertical walls or cliffs, avoid exposed mountains and ridges and flat open terrain.
7) Avoid ground fissures, patches of lichen, and suspended rocks. 8) You must not sit in the middle of scattered rocks.
9) Use a rope to secure yourself at the topography. 10) If you go into a hole to avoid lightning, you should leave all vertical walls 3 meters away to prevent the wall from causing electrical damage.
During heavy rains, due to rapid rainfall, the surface did not have enough time to absorb rainwater, and frozen soil and rocks were also difficult to stop the rain and water from escaping, which would aggravate the threat of mountain torrents. Therefore, when the thunderstorm activity is intense, avoid the long gutters and the flat extension underneath the river bed. Depart from areas that are vulnerable to flooding and, if necessary, dispose of them to shift to higher grounds, taking care not to attempt to hike past streams that reach knees.
Weather conditions can increase or decrease body temperature and affect people's health. The three most important weather factors are temperature, wind speed, and relative humidity. Under cold conditions, the influence of temperature and the influence of wind are inseparable. Both tend to lose heat at the same time, and the soaking value of soaked clothes will drop by 90%. Therefore, a simple and easy way to survive in a cold environment is to maintain proper exercise without sweating. In a hot and humid environment, people may experience fatigue, headaches, loss of appetite, insomnia, severe dehydration, and general fatigue and enthusiasm. Attention should be paid to avoiding wild activities under this climate.
