Abstract

Two definite levels of subsidence inversions were found over the tropical Eastern Pacific Ocean during the winter of 1964; both were mainly persistent and continuous. The existence of the lower inversion has been known, but that of the upper inversion at a mean height of 550 mb. has not. It is hypothesized that the upper inversion is caused and maintained by the subsidence in the warm “dynamic” anticyclone centered over Central America during winter. Both inversions appear to act as “lids” on cloud height development.
