Abstract

Manifestations of both Rayleigh-Taylor instability and Kármán vortices in atmospheric flows are recognized, and existing theory is applied to infer some values for the horizontal and vertical eddy transport coefficients for momentum, Kh, and Kz, respectively.

Periodic protrusions of cloud material from beneath cirrus bands sometimes associated with warm frontal
