100 thousand why about meteorological problems

One hundred thousand reasons about meteorological problems are as follows:

1. What's the difference between climate and weather?

Climate refers to the long-term (usually 30 years) average weather conditions in an area, including temperature, humidity, rainfall and wind direction. Weather refers to specific weather conditions in a short period of time, such as sunny and rainy days today.

2. What is atmospheric pressure?

Air pressure refers to the weight of gas per unit area, usually expressed in Pascal (Pa). The atmospheric pressure on the earth's surface is 10 13.25hPa, also called standard atmospheric pressure, which is the atmospheric pressure perpendicular to the earth's surface at a certain point on the sea level.

3. Why does it rain?

It rains because the water vapor in the air forms a cloud after encountering certain conditions (such as high air saturation and unstable atmosphere), and the water droplets in the cloud increase after colliding with ice particles, and finally fall into the rain.

4. Why does it hail?

Hail is a kind of weather phenomenon in which water droplets are frozen by cooling updraft, and their inner layer expands continuously, and finally released to the ground in a spherical shape.

5. What is a tornado?

Tornado is a strong storm, accompanied by rapidly rotating air, low pressure area, destructive wind and turbulence. Tornadoes can cause serious property losses and casualties.

6. Why did the typhoon hit the southeast coast of China?

Typhoon is a frequent natural disaster in the northwest Pacific and southeast coast of China. This is because the typhoon generation area is located in the tropical cyclone generation zone, and the southeast coast of China is in the northwest Pacific Ocean, so typhoons are more likely to attack these areas.

7. How to forecast the rainstorm weather?

Rainstorm weather is mainly affected by many meteorological factors such as front, inversion line and vortex. At present, the rainstorm weather forecast mainly adopts high-tech means such as Doppler weather radar, and through continuous monitoring and analysis of various meteorological data, the specific rainstorm warning information is determined.

In a word, meteorology is a widely used scientific discipline, which plays an important role in our life and work. By mastering and understanding meteorological knowledge, we can better prevent and reduce disasters and protect people's lives and property.
