Assessment of input and dissipation packages for significant wave height during Tropical cyclones of varying intensity in Bay of Bengal

This paper attempts to study the wave hind cast effects of cyclones of variable intensities in North Indian Ocean. Sensitivity of different input-dissipation formulations (packages) in the TOMAWAC model to simulate integrated parameter, significant wave height are investigated at deep and nearshore locations. Statistical estimates are used to analyze the performance of the input-dissipation formulations against buoy measurements. The analysis suggested that the simulation through a variant of WAM 4 cycle package [1] bestowed WAM 4 cycle [2] and WESTH [3] packages.
