Thunderstorm dew point
WebIf dry mid-level air is drawn over very warm, moist air in the lower troposphere, a hydrolapse (an area of rapidly decreasing dew point temperatures with height) results in the region … WebHydrolapse- Rapid increase or decrease in dewpoint with height. (K)- K Index. The K Index is primarily applicable in the prediction of air mass thunderstorms. Low values of the K Index in the presence of other strong thunderstorms indicators (sharp trough, high level jet, etc.) may suggest a severe thunderstorm potential.
