Scientific meteorological manuscript

Little is known about scientific meteorology;

1. What is the weather? Weather refers to meteorological phenomena that occur in a short period of time (several minutes to several days), such as thunderstorm, hail, typhoon, cold wave and strong wind.

2. What is climate? Climate refers to the long-term average of various meteorological elements (month, season, year, year, even hundreds of years, etc.) in a certain area. It is a comprehensive reflection of the basic characteristics of cold, warm, dry and wet weather conditions in a region.

3. Climate resources: Climate resources refer to light energy, heat energy, precipitation, wind energy, etc. Widely exists in the atmosphere, which can be used directly or indirectly by people and can form wealth. It is a very precious renewable natural resource and the basic condition for the survival and development of human society, and has been widely used in all aspects of the national economy and people's livelihood.

4. Microclimate:? Microclimate is under the same general climate background. In some areas, this area has a unique climate because of the inconsistency of topography, soil conditions and vegetation.

The characteristics of microclimate are mainly manifested in the drastic changes of individual meteorological elements and the differences of individual weather phenomena.

7. Why is the air pressure higher in winter than in summer? Air pressure refers to the pressure produced by the air column per unit area on the earth. The air pressure in a place often changes. When the air pressure drops, it is rainy, the weather rises and the weather turns fine.

There are many reasons for the change of air pressure. The change of temperature is a very important reason for the change of pressure. When the air is cooled, the air contracts, the density increases, the weight of air column per unit area increases, and the air pressure also increases.

Therefore, the arrival of cold air is always accompanied by the increase of air pressure; When warm air comes, the air pressure tends to drop.

Winter is a world of cold air and summer is a world of warm air, so obviously, the air pressure is high in winter and low in summer.

8. Weather phenomena include cloudy, sunny, rainy, snowy and windy.

Weather factors such as precipitation, light and wind will affect people's production and life, including agricultural irrigation, wind power generation and solar power generation.

9. Why does it rain? It's water drops falling from clouds, and water on land and sea surfaces turns into steam. Steam rain rises to a certain height and turns into small water drops when it is cold. These days, it falls from the clouds and forms rain.
