Will different temperatures in the air also cause different winds at high altitude?

At mid-latitude, the wind has a certain relationship with the weather system. For example, in the northern hemisphere, people with their backs to the wind will find that the air pressure on the left is lower than that on the right. Therefore, people can judge the level of air pressure from the wind situation. Clockwise wind in one area, mostly high pressure; The wind that rotates counterclockwise is mostly low pressure. Where there is cold and warm fronts, the wind often changes clockwise, and the magnitude of the wind before and after the front is not equal. Moreover, the moving speed of some weather systems and their upper and lower structures can also be inferred from wind conditions. But on the ground, because of the complex terrain, rough ground, trees and flowers growing on the ground, and some buildings, the wind near the ground becomes very chaotic, so it is impossible to estimate the weather system. Only in the air at a certain height from the ground can the relationship between wind and weather system be more regular.

On the other hand, different temperatures in the air will also cause different winds at high altitude. This kind of high altitude wind caused by different temperatures is called thermal wind. People can infer the temperature distribution from the thermal wind. For example, in the northern hemisphere, people will find that the temperature on the left side is lower than that on the right side with their backs to the wind direction. Clockwise thermal wind appears in one area, mostly in high temperature area; Anti-clockwise thermal wind appears, mostly in low temperature area. In this way, we can judge the temperature distribution of the upper and lower air according to the distribution of thermal wind at different heights, so as to judge whether the gas layer is very stable and whether there will be thunderstorms.

In addition, the wind at a certain height can indicate the moving direction and speed of the weather system. This height is called the guiding layer. Finding the guiding layer is very helpful for forecasting weather changes.

In short, high-altitude winds can reflect many weather conditions. Therefore, when forecasting the weather, we should use the data of high-altitude winds. Of course, it is not enough to judge the future weather only by the high-altitude wind. We should also make a comprehensive analysis of the distribution of temperature, pressure, weather phenomena and wind in the upper air in order to make more accurate weather forecast.
