Papers in this volume are from a seminar on Parameterization of Sub-grid Scale Processes in Dynamic Models of Medium Range Prediction and Global Climate, held in Pune, India, in August 1990. Organization is around seven themes: cumulus convection and parameterization, land surface processes and air-sea interaction, radiation and the radiative effects of the clouds, geography and gravity wave drag, 4-d data assimilation and systematic errors of operational models, sensitivity studies, and biosphere and land surface processes.
