近年来,在热带大气环流和天气系统的研究中,人们愈来愈注意到两个半球之间的环流相互作用的重要性.研究表明,夏季西南季风主要来自南半球,而且来自南半球的越赤道气流有它相对集中的通道.由于不同作者使用的资料以及研究方法和范围的不同,从印度向东直到中太平洋,低空越赤道气流通道的经度位置和支数,看法还很不一致,从两支到多支.不一致的原因很多,主要是在分析研究中大多用常规资料,由于广阔洋面上的观测资料稀少,人们不得不以某几个测站代表某区域情况,使分析结果的精度可能存在
In recent years, more and more attention has been paid to the importance of the circulation interaction between the two hemispheres in the study of tropical atmospheric circulation and weather system. Studies show that the summer monsoon comes mainly from the southern hemisphere and the cross-equatorial flow from the southern hemisphere Has its relative concentration of channels.Due to the different data and methods used by different authors, the longitude and count of low-level cross-equatorial airflow channels from east to the mid-Pacific from India to India are still very inconsistent. From two to There are many reasons for inconsistencies, mainly due to the fact that most of the analytical studies are conducted using conventional data. Due to the scarcity of observational data on a vast ocean surface, people have to represent a certain area by a few stations so that the accuracy of the analysis results may exist
