现行的中学世界地理课本中,对于世界气候、气压带和风带、大陆自然带、洋流等知识非常重视。但对于与风带和气压带的形成有密切关系的大气环流知识却没有涉及,易“使学生知其然而不知其所以然”。因此有必要对大气环流,以及它与气压带、风带、洋流和世界气候类型的关系等方面,进行深入细致的分析,以帮助对教材的扩大理解和提高教学质量。什么叫大气环流?至今在气象学中还没有明确的定义。不同的人对大气环流有不同的理解。有人认为:“大气圈内空气的平均运动情况”;“大气圈内各种气流的总和”
In the current middle school world geography textbook, we attach great importance to the knowledge of the world’s climate, air pressure belts and wind belts, mainland natural belts, and ocean currents. However, knowledge of the atmospheric circulation that is closely related to the formation of the wind zone and the air pressure zone has not been involved. It is easy for students to know it but they do not know why. Therefore, it is necessary to conduct in-depth analysis of atmospheric circulation, its relationship with air pressure belts, wind belts, ocean currents, and the type of world climate in order to help expand the understanding of teaching materials and improve teaching quality. What is atmospheric circulation? There is no clear definition in meteorology so far. Different people have different understandings of atmospheric circulation. Some people think: “The average movement of air in the atmosphere”; “The sum of all kinds of airflow in the atmosphere”
