Description
Maximum wind speeds associated with tropical cyclones are estimated operationally by a very widely used tool, the satellite‐based Dvorak technique (SDT) of cloud pattern matching and infrared cloud‐top temperature analyses, but it still has its own limitations. To make a good forecast and its proper verification it is essential to estimate the location and current intensity of a cyclone accurately. This study compares intensity estimates of tropical cyclones over the north Indian Ocean by the Joint Typhoon Warning Center (JTWC) and the Regional Specialized Meteorological Centre, New Delhi (RSMCND). The results show that, except for super cyclones, the differences in intensity estimates are a function of intensity, the 12 hr intensity trend and the translation speed. The intensity estimates by the JTWC are often higher than RSMCND estimates. The mean absolute difference (MAD) and the root mean square …
