Abstract: | A three-dimensional numerical model of the type described by Johns and coworkers (1992), hereafter referred to as model (J),
is applied to study the response of a coastal ocean to pure wind-stress forcing. Conservation equations are applied for mass,
momentum, temperature, salinity and turbulence energy. Experiments are performed to investigate the evolution of the thermal
structure and upwelling processes along the east coast of India during the pre-monsoon season. A comparison between the computed
results and the limited observations on the thermal structure and alongshore currents over the inner-shelf off Visakhapatnam
is presented. |
