Instability Index and Saturation Fraction in Mid-Latitudes

A correlation has been observed in the tropics between the instability index and the saturation fraction. The authors look to see if this correlation holds at mid latitudes in convective systems. Atmospheric sounding data from all 66 stations in the U.S. between the latitudes of 30 and 60 degrees from the years of 2007 to 2017 are utilized for this analysis. This is a preliminary analysis to determine if a full study of 30 years of past sounding data is warranted. If this correlation is found to exist in mid latitudes, the findings of this study could be used to improve climate models leading to more accurate predictions of both weather and climate change.
