How do shortwave troughs develop
Webdevelopment of mid-latitude cyclonic storm in wavelike manner along polar front Frontal Wave wavelike kink that forms on the front of a cyclone Central Pressure region of lowest pressure at the junction of two fronts Open Wave narrow band of precipitation that normally moves east or northeastward Warm Sector 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.
