Abstract
Several excellent examples of open and closed mesoscale cellular convection (MCC) were observed in DMSP satellite imagery during the second field period of the Air Mass Transformation Experiment (AMTEX), conducted 14–28 February 1975 over the East China Sea in the vicinity of the Kuroshio current. The kinematic fields of horizontal divergence, vertical motion and vorticity of the large-scale flow producing the MCC and the associated heat flux at the air-sea interface were determined to starch for observational evidence as to the cause of circulation direction in the convection cells. None of these kinematic fields had features unique to open and closed cells, with predominantly downward vertical motion and diverging horizontal flow in the convecting layer. From the study of the kinematic fields determined for 14 cases of open cells and 20 cases of closed Cells a physical depiction has been made of the distribution of the vertical motion in the vertical plane of a mesoscale cell during its formati...
