Short Answer Which weather systems produce rising motion?

Cyclones and anticyclones are the two most basic weather systems. Just like large and small vortices in rivers, there are also various different vortices in the atmosphere. They rotate along with the mainstream, One side moves forward. In the Northern Hemisphere, a large vortex of air that rotates counterclockwise around the center is called a cyclone; a large vortex of air that rotates clockwise around the center is called an anticyclone. In the Southern Hemisphere, the opposite is true, and cyclones rotate clockwise. The anticyclone rotates in the counterclockwise direction. In the westerly belt, the cyclone and anticyclone move from west to east with the basic air flow; in the easterly belt, the cyclone and anticyclone move from east to west with the basic air flow. Cyclone Convergent updrafts prevail in the sky. Anticyclones prevail in the sky. Radiative downdrafts prevail in the sky. Cyclones and anticyclones are large weather systems with a wide range of influence. The diameter of a cyclone is generally 1000 kilometers, small ones are 200-300 kilometers, and large ones can reach 2000 kilometers. -3000 kilometers. Anticyclones are larger, and their maximum range can be compared with continents and oceans. The formation and movement of cyclones and anticyclones have a great impact on the weather in large areas. Analyze and forecast the occurrence, development, and movement of cyclones and anticyclones and changes are important elements of weather forecasting. In a cyclone area, the airflow converges from the outside to the inside, and the airflow carries the water vapor in the ground air layer up, cooling and condensing to high altitudes, forming clouds and rain. Therefore, the airflow in the cyclone area The weather is generally cloudy and rainy. In the anticyclone area, the airflow diverges from the inside to the outside, and downdrafts prevail. The weather is generally sunny. Since my country is located in the mid-latitudes, cyclone and anticyclone activities are quite frequent. Mainland my country Many dramatic weather changes in the world are mostly caused by cyclones and anticyclones. For example, in winter, the Mongolian Plateau in northern my country has very cold weather, often forming an anticyclonic high pressure center. Once this cold anticyclone moves south, it will bring great consequences to our country. A strong cold wave has been brought to a vast area, seriously affecting our country's weather. Another example is a typhoon, which is a very powerful tropical cyclone, accompanied by violent winds, rain, and rough seas.
