What is the wind blowing in the north in winter and what causes it?

In areas where the sea is located in the north (such as Tianjin), it is easy to blow the north wind in winter, and the reason should start from the formation of the wind. Wind is formed by air flow. On the ground, it flows from low temperature to high temperature. In winter, the ocean currents in the sea also change more than in summer, mostly cold currents.

Due to the huge temperature difference between the ground and the sea surface formed by the cold current, a cold wind is formed. At this time, the sea surface temperature is much lower than the ground, and the formed wind blows to the land, that is, the north wind.

Matters needing attention when going out in windy weather:

1. Users are advised to wear masks. In windy weather, cold air quickly enters the respiratory system through the nasal cavity, which will stimulate the throat and lungs and cause sore throat and cough. In addition, the climate in the north is dry, and windy weather will be accompanied by dust. If you don't wear a mask, your mouth and nose are covered with dust.

2. Users need to wear windproof clothes. Be sure to wear a windproof coat and trousers on windy days, or you will feel the cold wind biting. Jeans and winter clothes are a good match. Don't wear cashmere coat for coat. Although the cashmere coat is warm, it is too breathable.

3. Wear a hat fixed on clothes. On windy days, many users have to press their hair by hand, only to find that the hairstyle has become a bird's nest when they enter the room. It is suggested that women can tie their hair in windy days, wear clothes with hats and put on hats when going out. Don't wear berets.

4. Avoid billboards, dead trees and temporary buildings. Billboards, dead trees, chandeliers and temporary buildings are all potential dangers in windy days. These things are easily blown down by the wind and hurt pedestrians.
