AN INVESTIGATION OF TIME VARIATIONS IN A SUBTROPICAL JET STREAM AND THE ASSOCIATED CLOUD PATTERNS AS SHOWN BY TIROS I

摘要

A cloud band along the south side of the subtropical jec stream over the Gulf of Mexico was pictured by the TIROS meteorological satellite on 5 April 1960. The subsequent development of this cloud band for a five-day period was pictured by regular TIROS observations. The TIROS data were combined with conventional surface and upper air data to obtain a more detailed analysis of the situation. The cloud band was shown to consist mainly of middle and high clouds. Cross section analysis supported the possible inter-relationship of the cloud band, the so called jet front, and the jet stream. Support for the theory that the lifting occurs in the area of entrance on the south side of the jet stream was also found. A good fit with the jet stream model of Endlich and McLean was noted.
