一般说来,同一水平面上只要有气压差的存在,就有促使大气由高气压区流向低气压区的水平气压梯度力,就会形成风。季风也是气压梯度力作用的结果。根据这一基本原理,以下分别叙述亚热带、温带海陆之间的季风与热带陆陆之间的季风成因。一、亚热带、温带海陆季风的成因亚热带、温带相近的纬度在不同季节海陆间高低气压中心的变化,改变了大气的三圈环流模式,也就改变了气压带和风带移动所造成的影响。这种情况在同为北半球或同为南半球的亚热带、温带大陆东部的陆地与海洋之间较为明显。同为南半球或者北半球的相近纬度的大陆东部,有
In general, the same level as long as there is a pressure difference exists, there is to promote the atmosphere from the high pressure area to the low pressure area horizontal pressure gradient force, it will form the wind. Monsoon is also the result of pressure gradient force. Based on this basic principle, the monsoon causes between the monsoon and the tropical land and the sea in the subtropical and temperate zones are described as follows. 1. Causes of Subtropical and Temperate Sea-Land-Monsoon Changes in the subtropical and latitudinal latitudes at different altitudes in the high and low pressure centers of the sea and land changed the three-circle circulation pattern of the atmosphere and changed the effects of the atmospheric pressure zone and the movement of the wind zone. The situation is more obvious between the land and the sea in the same subtropical or temperate continental east as the northern hemisphere or the southern hemisphere. It is the same as the eastern part of the continent with similar latitudes in the southern hemisphere or the northern hemisphere
