摘要

The hourly meteorological data available from hitherto unrepresented locations due to the installation of satellite-based Automatic Weather Stageries from Kalpana-1 satellite. The pressure defect and maximum winds in the cyclone field have been computed by using a theoretically derived proportionality constant (K). An analysis on the effect of environmental flow, direction of movement and friction on the maximum winds observed in a land station has been made using the wind speed values recorded by AWS at Ennore Port located north of Chennai. The possible lower bound of wind speed of the cyclone while out at sea has been computed and verified that the operational declaration of the TC Jal as a cyclonic storm at 0600 UTC of 7~(th) was correct.
