Four models were evaluated to develop an operational method of estimating surface variables with research aircraft flight-level (500 m) data; the models plus two estimation methods were com- pared with 'ground truth' buoy and ship wind speed data from hurricanes Eloise and Anita and vertically stacked several-level aircraft data in Eloise and Caroline. Three of the models were capable of estimating wind speed to 10% accuracy; 10 m level neutral drag coefficients were compared with previous studies.

A procedure is presented to improve the prediction of tropical storm paths when two or more rawin- sonde observations are within the storm-influenced region. Substantial improvements in position forecast accuracy are possible out to the 72-hr range. Department of Meteorology, Massachusetts Institute of Technology, Cambridge, Mass. 02139, U.S.A. (mcs)

Southwest Monsoon of 1972 and 1979. Curr. Sci., 49(4): 123-129.

India has experienced severe and widespread drought five times in the last century: 1877, 1899, 1918, 1972, 1979. Inhibition of the Southwest Mon- soon rains is linked to a blocking ridge 90-115°E that obstructs the eastward movement of westerly troughs. Additional synoptic and dynamic studies are needed for effective drought management pro- grams. Meteorological Office, New Delhi-3, India. (izs)

In the area 0-46°N, 90-155°E, northerly winds prevail in winter and southerly winds in summer with April and October being transitional intervals and the transition progressing seaward from the coast. Influence of the Taiwan Strait on monsoonal circulation is considered. Institute of Geography, Academia Sinica, People's Republic of China. (izs)

Mountain barrier baroclinity is studied using data from buoys deployed on the Arctic ice in February 1979 which relay pressure and location information and from rawinsonde data from Barter Island. The wintertime abundance of W-SW winds along the Alaskan Arctic coast is shown to be a result of mountain barrier baroclinity.

The production, concentration, and vertical distribution of the sea-sal t aerosol. Ann. N. Y. Acad. Sci., 338: 330-347.

A review of the literature on atmospheric sea salt and some new data on its vertical distribution are presented. The bursting of bubbles, resulting in large part from whitecaps, is thought to be the origin of most salt aerosol. It is estimated that 10 ~ to 10 J° metric tons of salt aerosol are produced each year. More data on bubble spectra, adsorption, the relative importance of jet drops and film drops, geographic differences, the effect of water temperature, and the vertical distribution of sea salt are needed.
