A Simple Identification Scheme for Upper-Level Troughs and

WebMar 15, 2004 · Abstract A simple algorithm for the identification of upper-level trough axes is introduced. In contrast to the assumption of a basically circular geometry in many comparable routines found in the literature, the presented identification scheme is based on the east–west gradient in the 500-hPa geopotential height field, accounting for the … WebHowever, like polygonal troughs, the trunk channel of the dendritic troughs tr 2 displays undulating longitudinal profiles ( Figure 2 C) and U-shaped cross sections when the vertical exaggeration ... WebA trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a … long term effects of ed drugs
