The weather system always has a new, developing and dying process, and there are corresponding weather phenomena in different development stages. It can be seen that the weather and climate change in a region is related to the weather system and its development stage, and it is the comprehensive result of atmospheric dynamic process and thermal process.
All kinds of weather systems are formed, developed and evolved in a certain atmospheric circulation and geographical environment, and all reflect the environmental characteristics of a certain area. For example, the polar regions and their surroundings are covered with ice and snow all year round, and the air is cold and dry. The unique geographical environment has become the background condition for the formation and development of polar vortex and trough with low cold and high pressure and high altitude. It is necessary for the development of convective weather system that the equatorial and low latitudes are hot and humid all year round and the atmosphere is unstable. At high latitudes, it is often the suppression area of cold and hot air flow. Not only the temperature changes frequently, but also the baroclinic is unstable, which is the basis for the formation and development of frontal and cyclone systems. The formation and activities of weather system will in turn have a profound impact on the structure and evolution of geographical environment. Therefore, it is very important to understand and master the relationship between weather system and its formation, structure, movement change law and geographical environment for understanding the formation, characteristics and changes of weather and climate and predicting the evolution of geographical environment.
Weather forecast is the science of human development to predict the weather. Today, from proverbs to the use of computers to the operation of Naville-s Stokes equation, numerical prediction in the history of science has a long history. Today's weather forecast can make the weather forecast more accurate in a week. There is no w most gas forecast reporting the maximum and minimum temperatures; Rainfall probability and magnitude; Sunny, cloudy, ultraviolet index, cold index and so on.
"Wet weather" prevents moisture and minimizes the temperature difference between indoor and outdoor.
Experts say that "wet weather is conducive to the growth of bacteria" and it is easy to make food, clothing, furniture and other items moldy. Use heat source equipment such as central heating and electric oven to heat the room so that the indoor temperature is equal to or slightly higher than the outdoor temperature; The second is to try to keep the warm and humid airflow undisturbed. Use the dehumidifier function of the device.
Spring rain, more often, is a few days, even more than ten days. At this time, as long as the weather turns into a "southerly wind", the tiles, walls and painted surfaces of furniture on the ground are all wet "sweat". This is a typical "damp" phenomenon.
In the face of humid weather, the following measures can be taken to prevent or alleviate it: First, reduce the temperature difference between indoor and outdoor as much as possible. Use of heating, electric oven and other heat sources

For indoor heating, make the indoor temperature equal to or slightly higher than the outdoor temperature; The second is to try to keep the warm and humid airflow undisturbed. Once the wind direction is found to be from north to south, doors and windows should be closed in time, and indoor wardrobes and cabinets should be locked to reduce the entry of outdoor air; The third is to put some hygroscopic materials indoors. More economical and ideal is quicklime (massive lime), which absorbs moisture in the air and releases heat after melting, which has a heating effect on the room; The fourth is to use equipment for dehumidification. The air conditioner with dehumidification function will be turned on immediately; Conditional also can use () to filter indoor air, with a dehumidifier "dehydration".
Main weather elements: wind, clouds, fog, rain, snow, frost, thunder, hail, etc.
