Description An attempt has been made to examine the relationship between UOHC and Uh for the severe cyclones during 1990-2006. Uh has been computed from 6 h track positions of each storm (www.imd.gov.in; T3.0 onwards) and the corresponding UOHC (it was given as ‘tropical cyclone heat potential’ prior to the storm) data were taken from the NOAA website (http://iridl.ldeo. columbia.edu/SOURCES/.NOAA/.NCEP/ .EMC/.CFS/.DAILY/.BelowSeaLevel/)6. Data for 13 severe cyclones during premonsoon (April and May) and postmonsoon (October and November) seasons were used in the computations. Details of the period, lowest central pressure (mb) of the storm, maximum sustained wind speed (kn) and the intensity (T number) of the storms are shown in Table 1. Low (less than 2 m/s) and high (more than 9 m/s) values of Uh were avoided in the analysis. Due to nonavailability of real-time datasets, we were forced to use the pre-storm UOHC data from the NOAA website
