WebTo affirm the convergence in the surface trough (where the squall line formed), please note the confluence of the wind barbs (southerly just ahead of the trough and west … WebMar 5, 2005 · Troughs aloft can be found on constant pressure charts, and are best identified on constant pressure charts above 700 millibars, which roughly corresponds to 10,000 feet msl. This means checking the 700-millibar constant pressure chart, as well as the 500-millibar (18,000 feet) and 300-millibar (30,000 feet) charts, to learn the telltale … A trough is an elongated area of lower air pressure. Since pressure is closely linked to wind, there are often changes in wind direction across a trough. If a trough forms in the mid-latitudes, a temperature difference at some distance between the two sides of the trough usually exists and the trough might become a … See more 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, See more A trough is the result of the movements of the air in the atmosphere.
