Wimbush, 1985. Wind-current coupling on the southern flank of Georges Bank: variation with season and frequency. J. phys. Oceanogr., 15(5): 604-620.

Wind-current coupling is primarily between long- shelf wind stress and longshelf current; weakest coupling is in late summer and early fall when the water column is highly stratified. The coherence and transfer coefficient is highest for periods between 4 and 12 days, decreasing both for longer and shorter periods. Models indicate that a highly damped resonance may exist on Georges Bank and that a smaller current response is expected when the water column is stratified. Observations indicate that the wind-driven currents are strongly controlled by friction. The near-surface current moves to the right of wind stress and there is a spring-neap modulation of the transfer coefficient caused by modulation of the bottom stress. The longshelf current is linearly related to wind stress and responds almost symmet- rically to wind forcing. USGS, Menlo Park, CA 94025, USA.

Joseph, 1985. Surface heat budget estimates at selected areas of north Indian Ocean during Monsoon-77. Mausam, 36(1):21-32.

Significant differences in the characteristics of heat budget components during the onset and progress of summer monsoon are noticed. Spatial non-homo- geneity in the energy feed to the monsoonal flow from the ocean surface is highlighted. Energy input to the atmosphere from the ocean during disturbed weather is approximately double the corresponding value during fair weather. Naval Phys. & Oceanogr. Lab., Cochin, India.

annual baroclinic Rossby waves to wind forcing in the eastern midlatitude North Pacific. J. phys. Oceanogr., 15 (4): 403-415.

A baroclinic, nondispersive Rossby wave model driven by observed wind stress curl is compared with observed interannual anomalies of 300 m temper- ature in the eastern North Pacific. A resonant response of the Rossby waves to the wind stress curl is found in which the wave starts at the coast of North America and propagates westward with

amplitude increasing linearly. Off-resonant response in the real ocean occurs in the dispersive portion of the spectral domain where the model is not appli- cable. This, together with noise in the observed temperature and wind data, is responsible for the model's inability to account for more than 20% of the observed variance.

1984/85. Results of the studies of monsoon circulation with radon as a tracer. Pure appl. Geophys., 122(1): 124-132.

Radon-222 measurements taken during summer monsoon periods of 1973, 1977 and 1979 from the Indian Ocean, Bay of Bengal and Arabian Sea confirmed the wind system's Southern Hemisphere origin, with a continental component which in- creased at high latitudes and varied with different synoptic conditions. Radon's usefulness in distin- guishing between and assessing relative contribu- tions of continental and maritime air masses is discussed. Bhabha Atomic Res. Center, Trombay, Bombay 400 085, India.

There is a good correlation between calculated geostrophic winds and observed winds. Calculated gradient winds have a better relationship to observed winds, especially under typhoon regimes. Kobe Mar. Observ., Kobe, Japan.
