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. Webthe static stability index was made by correlating the 1500 GMT Showalter stability index with the 2100 GMT Showalter stability index for the same soundings used above. FIGURE 3 is a plot showing the relationship be-tween the stability index at 1500 GMT and the stability index determined from the 2100 GMT sounding at the same station. buck county sheriff sales
