Abstract
A remarkable inversion layer was observed over the Japan Sea under a winter monsoon situation on Jan.30,1965. Detailed analysis on the structure of this inversion layer and on the behavior of the cumulus convection in the sub-inversion layer is made by using the data of dropsonde and aerial photographic observations.
It is found that the convective clouds exist only in sub-inversion layer and no evidence of air mass modification is observed above the inversion. Also a high correlation between the mesoscale undulation of the inversion layer and the groups of active convections is analysed.
