RED-SEA WATER LENS FORMATION IN ARABIAN SEA
Abstract
Historical CTD data collected in March - April 1980 in the North West Indian Ocean are used to find out a young lens of Red Sea Water at the stage of its formation. The lens is located in the depth range of 640 - 830 m. Temperature and salinity values in the core are 11.07-degrees-C and 35.56 parts per thousand whereas maximum anomaly with respect to background waters are 0.75-degrees-C and 0.22 parts per thousand. Temperature - salinity structure as well as dynamics, energy and vorticity distribution in the lens is analyzed. A probable trajectory of the lens is estimated using T-S analysis, Lagrangian invariants and neutral surface methods. It is shown that the lens is formed as a result of interaction of a cyclonic meander with a tongue of Red Sea Water. A new physical mechanism of intrathermocline lens formation is suggested that could be called ''stimulated generation mechanism''.
