Computer generated Skew-T plot (pseudoadiabatic diagram) <br />of project Muddy Road IV supplemental upper air balloon <br />sounding, Lakin, Kansas, May 10, 1978, 2300 hours GMT. <br /> <br />In addition to plotting the conventional dewpoint tempera- <br />ture and temperature curves, the computer also plots the <br />mixing ratio and dry adiabat (dotted lines) used to compute <br />the convective condensation level (CCL) and the surface <br />temperature at which convective clouds will be initiated. <br /> <br />A computer generated dashed line extends from the CCL <br />along the moist adiabat to its intersection with the tempera- <br />ture curve. The resulting enclosed area is a measure of <br />the "buoyancy" or instability of the atmospheric layer. <br /> <br />21 <br />
