Abstract
This note reviews recent diagnostic studies of the atmospheric heat and moisture sources using aerological data. It appears that the large-scale features of evaporation minus precipitation, as well as of the diabatic heating of air in general, can nowadays be deduced from three-dimensional fields of aerological variables relatively accurately. However, the usefulness of the aerological method for smaller scales, e.g., those associated with the BALTEX (Baltic Sea Experiment), remains to be established.
