Description Marine operations of various types are critically linked to mean and extreme wave statistics. In the Indian seas extreme wave conditions are caused by cyclones and steady strong monsoon winds. Wave data from cyclone areas are not directly available in plenty. The situation can be improved by hindcasting waves using wind fields of past storms. A method to hindcast storm wind fields is presented in this paper. The method is based on the standard Hydromet pressure profile. The input variables are, (1) radius of maximum wind, (2) central pressure, (3) storm speed, (4) direction of storm movement, (5) latitude and (6) longitude. These are obtained from charts prepared by the India Meteorological Department. The computed wind fields agreed well with other published results.
