Local Finite‐Amplitude Wave Activity of Water Vapor as a Diagnostic of Atmospheric River Events
Abstract We generalize the formalism of local wave activity of quasi‐geostrophic potential vorticity to water vapor, defined as LWA‐V, and derive the LWA‐V budget equation. LWA‐V measures the waviness of moisture contours from the zonal symmetry in the eddy‐free atmosphere. It delineates well the no...
