Expanding the sample beyond single-storm cases, surface
convective available potential energy (CAPE) was evaluated for the regions underneath RHESSI at the times of 805 TGFs.
Each value is taken as an area-averaged measurement (except for
Convective Available Potential Energy or CAPE at the time this study was conducted) for the period of August, September and October for each year, resulting in three data points per year over twelve years.
Another chart you can search for on the Internet is CAPE,
convective available potential energy. This is widely a meteorologist's favorite tool to evaluate instability.
To contribute to the understanding of MCSs in the inter-Andean region of Southern Ecuador, the present study estimates the climatology of MCSs and their climatological thermodynamic and dynamical related variables such as the
convective available potential energy (CAPE), convective inhibition (CIN), and Omega and provides an initial exploration of the most relevant teleconnections affecting interannual variability of MCS occurrence in the Paute River basin.
A potentially severe day occurs when the product of
convective available potential energy (CAPE) and 0-6-km bulk wind shear [deep-layer shear (DLS)] exceeds 10,000 [m.sup.3] [s.sup.-3] at the same time that both factors exceed marginal thresholds (CAPE > 100 J [kg.sup.-1] and DLS > 5 m [s.sup.-1]) in order to rule out any days with negligible CAPE or deep-layer shear.
Convective available potential energy, or CAPE, is measured by radiosondes, balloon-borne instruments released around the United State twice daily.
