一、考纲解读高考考纲要求考生掌握“全球气压带、风带的分布、移动规律及其对气候的影响。”全球有七个气压带和六个风带,可以借助三圈环流来理解它们的形成和分布规律。三圈环流是假设地球表面均匀情况下的理想模式,实际上气压带和风带在近地面的分布是不连续的,并形成一个个气压中心。气压带、风带在一年内随季节作周期性移动,其根本原因是太阳直射点的回归运动。以气压带、风带的分布及其移动 First, the syllabus interpretation of the college entrance examination syllabus requires examinees to master “the global pressure zone, the distribution of the wind band, the movement of the law and its impact on the climate.” There are seven pressure zones and six wind bands in the world, which can be understood with the help of three circles of circulation. Their formation and distribution. Three-circle circulation is an ideal model for assuming a uniform surface of the earth. In fact, the distribution of the pressure zone and the wind zone near the ground is discontinuous, and a pressure center is formed. Pressure belts and wind belts periodically move with the season within a year. The fundamental reason is the return movement of the sun's direct point. The distribution of pressure bands and wind bands and their movement
