A Simple Kinematic Source of Skewness in Atmospheric Flow Fields

Abstract:

Geopotential height fields exhibit a well-known pattern of skewness, with distributions that are positively skewed on the poleward side of themidlatitude jets/storm tracks and negatively skewed on the equatorward side. This pattern has often been interpreted as a signature of nonlinear dynamical features, such as blocking highs and cutoff lows, and there is renewed interest in the higher moments of flow variables as indicators of the nature of the underlying dynamics. However, this paper sugg...
