Research Abstract

Kelvin-Helmholtz Instability(KHI) and KHI-induced atmospheric turbulence contribute to vertical transportation of heat and substance. However, it is difficult to observe them since their scale is very small. We analyzed them using high resolution imaging observation mode of the MU radar in addition to multi-frequency band radar and lidar observations. The structure of KHI and the relation between KHI and wind shear were clarified.
