Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.

通过对副高的描述、形成及演变特征和物理机理的研究进行回顾，认为：副高是相对的气压的高值，是由于平均经圈环流的存在，使得有空气质量在副热带地区的堆积而形成的，成为带状，表现出在经度方向的不均匀，这是一种纬向平均的观点；同时，在这个平均的高压带上常常有闭合的单体存在，表现出纬向的不均匀。
