The tropical cyclone (TC) forecast verification procedure followed by India Meteorological Department (IMD) is reviewed herewith as compared to the standard prescribed by World Meteorological Organisation. The limitations in the present procedure and the future scope are presented and analysed.The IMD ...
India Meteorological Department (IMD) introduced the objective tropical cyclone (TC) track forecast valid for next 24 hrs over the North Indian Ocean (NIO) in 2003. It further extended the validity period up to 72 hrs in 2009. Here an attempt is made to evaluate the TC landfall forecast iss...
and in other cases they seem to rotate around the centre. The rotatingcloudbands often are associated with an apparent wobbling of the storm track. If this happens as the tropical cyclone approaches a coastline, there may be large differences between the forecast landfall positions and actual land...
Hence, an attempt has been made to develop an NN model to forecast seasonal TC activity over the north Indian Ocean (NIO). In the present study, the NN and multiple linear regression (MLR) using jackknife approaches have been used to predict the seasonal activity of TCs in the post-...

Surge observations that are identified in this review are added to SURGEDAT, a global storm surge database [Needham et al.,2013]. This archive provides the location and height of peak storm surge observations around the world since 1880. An interactive Web map of these data is available atht...
Heatmaps are shown of the ensemble-mean difference in minimum SLP (in hPa) between the historical and pre-industrial simulations and between the RCP4.5, RCP6.0 and RCP8.5 simulations and the historical simulation (blue/red), with minimum SLP from observations and the ensemble-mean historical sim...
