OCTOBER-DECEMBER 19G3 MONTHLY WEATHER REVIEW 487 THE MASS AND HEAT BUDGET OF THE ANTARCTIC ATMOSPHERE
Mean meridional wind components and eddy transports of sensible heat across 72’s. latitude are computed for each of six atmospheric levels from 850 to 100 mb., using 1958 data from 10 Antarctic stations. Mean vertical motions are obtained from the meridional wind components; a heat balance is struck...
