What are fronts and fronts, and how do they affect the weather?

The front is a narrow and inclined transition zone between cold and warm air masses. Because there is a considerable difference in temperature and humidity between different air masses, and this difference can be extended to the whole troposphere, when two air masses with different properties meet in the process of moving, there will be an interface between them, called front. The line where the front intersects the ground is called the front. Fronts and fronts are generally called fronts. The front can also be understood as the confrontation between two different air masses. Due to the great difference of air mass properties on both sides of the front, the air near the front is active, the front fluctuates strongly, and the airflow is extremely unstable, which often causes bad weather changes. Therefore, the front is one of the important weather systems. A narrow transition zone separating cold and warm air masses. This transition zone inclines from the ground to the side of high-altitude cold air mass. The width of the transition zone near the ground is only a few tens of kilometers, and it can reach 200-400 kilometers to the top. The length of the front can generally be several hundred kilometers to several thousand kilometers, and it can extend more than ten kilometers vertically. In this transition zone, the temperature changes greatly.
