Abstract


Abstract - In this paper, study of Cyclone THANE, formed in the North Indian Ocean in December, 2011, has been conducted through remote sensing technology. The formation, duration and evolution of the cyclone was monitored at SPARRSO ground station mainly using the hourly basis data obtained from MTSAT-1 and FY-2D/E Geo-stationary satellites. The imageries were analyzed using Vimsat, Gmsoft and Dvorak’s algorithm to find out the location, intensification and to observe the movement of the cyclone which is necessary for early warning and preparedness. The analysis showed that cyclone THANE was formed as a low on December 25. It was moving northwesterly at the early stage and then westward very slowly following a zigzag path. It was intensified gradually at the forming stage and rapidly afterwards. The pick was found on December 29, 2011. THANE then weakened slightly and made landfall on December 30 at early morning on South Indian coast battering the area with heavy rain and strong winds.
