Question

Sounding plotted on skew-T diagram

This sounding was taken at North Platte, Nebraska, at 1200 UTC 24 July 2000. It was associated with a severe supercell thunderstorm. North Platte lies at an elevation of approximately 2800 feet (910 hPa)

What is the convective temperature (Tc) for this sounding?

Tc = °C

Answer: Tc = 36°C.
From the surface dewpoint (Td = 17°C), proceed up the saturation mixing ratio line to where it intersects the temperature profile at 710 hPa. This pressure is the convective condensation level (CCL). Then proceed down along a dry adiabat to the surface pressure (910 hPa). The temperature at this intersection is 36°C, which is the convective temperature (Tc).
