http://www.csgnetwork.com/showalterindcalc.html WebThe Showalter Stability Index is a measure of the stability of the atmosphere in a local region. It is determined by lifting an air parcel to 500 millibars and then comparing its temperature to that of the environment. If the parcel is colder than its new environment, then the atmosphere is more stable. makita brush cutter cordless

WebStability of the Atmosphere Total Totals Index (TT) The Total Totals Index consists of two components, the Vertical Totals (VT) and the Cross Totals (CT). The VT represents static stability or the lapse rate between 850 and 500 mb. The CT includes the 850 mb dewpoint. WebShowalter Indexis a measure of thunderstorm potential and severity. Especially useful when a shallow, cool layer of air below 850 mb conceals greater convective potential above. > 4 …
