METEOROLOGICAL ASPECTS OF THE DECAY OF TROPICAL CYCLONE 01A IN NORTH ARABIAN SEA (MAY 05-11, 2004)

Azmat Hayat, Zahid Rafi, Rehan Ahmad

Abstract


In changing climate scenario, the intensity and frequency of extreme events is also changing. Extreme events are often the consequence of a combination of factors that may not individually be carrying such devastating socio-economic and environmental impacts. The aim of work is to understand the dynamics of the SST and Wind fields in the development and decay of tropical cyclone 01A. Of particular interest is the impact of atmospheric forcing on the circulation patterns in open waters.  Satellite remote sensing data, in combination with other sources of information is used to analyze the cyclone structure during its course of development and found that on 9th May, 2004, upper level winds blew the storm apart and weakened it. SST fields around the cyclone dropped by 0.5-1.0°C on 9th May indicating the upwelling in the region. Combination of these factors resulted in the decay of cyclone in north Arabian Sea.
