resolved horizontal and vertical advection (first two terms on the rhs) and diabatic processes (third term rhs) which consider diabatic heating and the divergence of turbulent heat transport. The computation is done in a similar way as for the water vapor conservation equation where the lhs and the first two terms of the rhs are computed from the reanalysis data and the third term of the rhs is estimated as the difference between them. As noted before, the updates produced by the assimilation system

increased, the potential for UCG increased. Along with the environmental factors that may favor UCG, internal storm processes also inherently play a role in this process. Downdrafts, owing to both hydrometeor loading and diabatic microphysical cooling, result in the formation of cold pools beneath convective drafts. Under certain conditions, these cold pools may spread laterally and interact with neighboring cold pools, encouraging secondary CI and promoting UCG (e.g., Bluestein and Weisman 2000
