What wind?
In addition, there are sea breeze, land breeze, mountain breeze, valley breeze, foehn breeze, bitter breeze, cyclone and so on.
The winds in the world can be roughly divided into two categories.
One is astronomical wind, called planetary wind system, which is the airflow generated by the earth's rotation;
The other is local wind, which is caused by the earth's environment and is called local wind.
There are many kinds of local winds, the biggest of which is monsoon.
Monsoon is caused by the difference between land and sea, winter and summer.
In winter, the mainland is cold, the air pressure is high, the ocean is warm and the air pressure is low, so the air flow blows from the land to the ocean, and a dry and cold northwest wind blows;
In summer, the mainland is hot, the air pressure is low, the ocean is cool and the air pressure is high, so the air flow blows from the ocean to the land, and the southeast wind is hot and humid. ?
Extended data:
Wind is a natural phenomenon caused by air flow, which is caused by solar radiation heat.
Sunlight shines on the earth's surface, causing the surface temperature to rise, and the surface air to expand and become lighter and lighter.
After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down because it gradually cools and becomes heavier. Because the surface temperature is high, it will heat up the air, and this airflow will produce wind. ?
From a scientific point of view, wind often refers to the horizontal motion component of air, including direction and size, that is, wind direction and wind speed.
But for flight, it also includes vertical motion components, so-called vertical or ascending and descending airflow. Strong winds can move objects and their directions (mass of matter). The wind is very fast.
Wind is a natural phenomenon on the earth, which is caused by solar radiation heat.
Sunlight shines on the earth's surface, causing the surface temperature to rise, and the surface air to expand and become lighter and lighter.
After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down because it gradually cools and becomes heavier. Because the surface temperature is high, it will heat up the air, and this airflow will produce wind.
