What is the life period of cyclones? Which tropical cyclone lasted the longest?
Life period of a Tropical Cyclone over the north Indian Ocean is 5-6 days. It will have hurricane intensity for 2-4 days as against 6 days of global average. Life period of the longest lived Tropical cyclone in Indian seas is 14 days (2nd -15th Nov, 1886 & 16th – 29th Nov, 1964). Hurricane/Typhoon John lasted 31 days as it traveled both the Northeast and Northwest Pacific basins during August and September, 1994. (It formed in the Northeast Pacific, reached hurricane force there, moved across the dateline and was renamed Typhoon John, and then finally recurved back across the dateline and renamed Hurricane John again.) Hurricane Ginger was a tropical cyclone for 28 days in the North Atlantic Ocean back in 1971. It should be noted that prior to the weather satellite era (1961) many tropical cyclones’ life cycles could be underestimated.
