Abstract: The wind induced hydrodynamics of Lake Neusiedl focusing mainly on the pelagic areas were successfully explored by using up-to-date Aanderaa recording current meters. In this very shallow lake, largely covered by reed, apart from oscillatory motions large scale baywide horizontal gyres were found to be predominant in long stable stormy periods. Bays with the same orientation showed circulation in the same sense of revolution, due to the similarities in the surface wind shear stress distribution. Interbay water exchange processes can be interpreted as a combined mechanism of oscillatory and circulatory motions. At connecting straits, oscillating water masses are flushed away by the existing circulatory motion, thus promoting the net exchange, which would be cumulatively very small in pure oscillatory conditions. Recommendations to extend the research to the reed covered areas also are given.
