Shallow Water Wave Characteristics during Laila Cyclone Using Satellite and In-situ Wave Measurements

Abstract

Extreme weather events like cyclones cause severe damage to coasts by inducing very high waves. Studies of such waves are important for several coastal processes. Satellite altimetry data used to study one of such extreme events LAILA cyclone during the year 2010 over Bay of Bengal. This cyclone caused severe erosion along the coast and of course first ever severe cyclone crossed Andhra coast since may- 1990. The satellite altimetry data showed that prolonged high waves during and after the cyclone. The in-situ observations show wave heights up to 3m under the influence of cyclone. The satellite altimetry gridded data performs well with In-situ data. Keywords: Coastal processes, Erosion, Extreme events, Satellite altimetry, Wave heights
