A diagnostic study using the CASP (Canadian Atlantic Storm Program) dataset and available precipitation data is performed to examine the thermodynamics of melting-induced mesoscale circulations. Various terms of the thermodynamic equation were evaluated. The horizontal and vertical advection terms were calculated using the rawinsonde data while the diabatic term due to melting was parameterized using surface precipitation observations. The effects of evaporation and dissipation were neglected in the calculation of the diabatic terms. The importance of the melting term was clearly shown although direct evidence of a melting-induced circulation was not found due to the relatively low resolution of the datasets used.
