Long and short waves in the upper-level flow

WebApr 7, 2015 · Shortwave troughs are features in the general flow of the atmosphere that are very important when it comes to forecasting, particularly for convective features and winter weather. Shortwaves can be thought of as "weather-makers," whereas Longwaves (Rossby Waves) might then be "trend-makers."

If other conditions are favorable, … WebSo, as a developing mesoscale forecaster, you should think of divergence east of a 500-mb shortwave trough as a way to "prime" the troposphere for deep-most convection. Indeed, a 500-mb shortwave does not really "trigger" thunderstorms. It simply makes the environment more conducive for thunderstorms to develop because it helps to reduce CIN. inclusive bike

WebFeb 7, 2001 · A baroclinic wave can develop in the atmosphere when the wind at a given pressure level is blowing parallel to the temperature (or potential temperature) isotherms and there is a nonzero temperature gradient across the flow.
