Understanding weather - fronts, troughs and ridges

A 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 low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mar… WebAug 24, 2024 · A front is an example of a surface pressure trough. [Courtesy: aviationweather.gov] In general terms, a trough is simply an elongated area of low pressure with no distinct low-level pressure center. WebBesides being housed in a pressure trough, a cold front also lies in a thermal ridge, which is a northward bulge in the surface isotherms (red lines on the graphic above). A thermal ridge marks an elongated area of maximum warmth, supporting the notion that temperatures typically increase along or just ahead of a cold front. That may seem ... tbikamera
