- Abstract
- We analyzed rawinsonde data sets during the 10-year summer seasons (June, July, August and September) of 2010-2019 at the five stations of Baengnyeongdo, Osan, Pohang, Gwangju, and Heuksando over the Korean peninsula. The 10-year soundings were grouped into two subsets: one is for high Convective Available Potential Energy (CAPE) and low Convective Inhibition (CIN) values whereas the other is for low CAPE and high CIN values. We statistically evaluated whether or not the two subsets are significantly different in terms of the thermodynamic parameters and atmospheric stability indices. As a result, all the considered parameters are significantly different between the two subsets. We present the details in this paper. Lastly, we present the composite soundings of high CAPE and low CIN, and low CAPE and high CIN.
- Keywords : Atmospheric stability indices, high CAPE and low CIN, low CAPE and high CIN, rawinsonde, thermodynamic parameters.
