Megha 2700, S-band ground-based Doppler weather radar (DWR) located on the east coast of India, is capable of providing long range detection and characterization precipitation and severe storm such as tropical cyclone over Bay of Bengal. The location of the radar is in coverage area of Tropical Rainfall Measurement Mission (TRMM) satellite. Precipitation radar (PR) operating at Ku-band (13.8 GHz) abroad the TRMM has capability of providing vertical structure of tropical cyclones. Although tropical cyclones can be frequently observed by PR, and their vertical structure can be studied, it is not so frequent that they are observed by most existing Ground based weather Radars (GR). The authors take this opportunity for performing inter-comparison between the two radars and inter-compare vertical profile of reflectivity (VPR) of tropical cyclone which were simultaneously observed by the Megha 2700 DWR and PR. This work can be useful not only in cross-monitoring severe tropical cyclone activity in a long range over Bay of Bengal, but also as ground validation study of TRMM, and even to the future global space based precipitation mission such as Global Precipitation Measurement (GPM), which is planed to fly over the globe in the near future.
