Description 1236-1240
Wind,
wave and current data collected at/off Ratnagiri, west coast of India
were analysed to study the wind-wave-current interaction along the west coast
of India (WCI) during shamal events. Shamal winds which originate in the
Persian Gulf region during winter (November-March) generate swells in the
northwestern Arabian Sea, and these swells propagate towards the west coast of India
with distinct wave direction (northwest) and increase in wave heights. It is
observed that during these events, the de-tided current data present a distinct
change in the current direction and increase in current speeds (approximately
from 0.08 m/s to 0.15 m/s). It can be inferred from the analysis that the waves which
propagate from NW and the currents which flow towards north oppose each other,
resulting in intensification of currents off Ratnagiri. In order to understand the
intensity of shamal effect on the existing current system, we have also
analysed winds and currents before, during and after the events.
