In this work, we explore the relationship between convection and the spatial variability of entropy in the boundary layer inside the EPIC box, (91-97)W-(8-12)N.

The satellite infrared temperature average over the EPIC box is used as a surrogate for convection. The entropy variance is obtained from in-situ measurements made in the boundary layer by the NCAR-C130.

The analysis shows that for this region, a significant correlation exits between the variance in the boundary layer entropy and convection that took place about 12 hours before the measurements of entropy.
