Generation of an Intense Subsurface Current by a Squall Passing over the Sea.

Data on an unusual case of measuring the current that occurred during the passage of a squally wind over the sea are presented. Measurements were performed on October 12, 2011, in the waters of the Black Sea shelf near Gelendzhik within the boundaries from the Golubaya Bay beam to Cape Tolstoy on a yacht equipped with a Rio Grande 600-kHz ADCP. An unusual intense subsurface current (up to 1 m/s) was revealed that penetrates 8 m deep, generated by a strong squall passed over the shelf zone. [ABSTRACT FROM AUTHOR]
