Analytical Study of the Low-Level Jet Stream

Abstract

The low-level jet stream which appeared near the meso-low on the “Baiu” front, the stationary front in the rainy season in Japan, is analyzed. It is revealed that its dimensions were 500 km in diameter and 4km in depth. It is also found that the jet core preceded the meso-low center, and the strong vertical current appeared in the lee side of the jet core. An improved technique is applied on the aerological data analysis.
