North Indian Ocean tropical cyclone seasons 2003, 2004, 2005, 2006, 2007

The 2005 North Indian Ocean cyclone season has no bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.

The scope of this basin is limited to north of the Equator and west of the Malay peninsula. The IMD and JTWC monitor this basin. The Arabian Sea and Bay of Bengal make up this basin, abbreviated ARB and BOB, respectively.

Season summary

In 2005, a total of twelve cyclonic disturbances were identified in North Indian Ocean, against a normal of fifteen. However, it was highest after 1992. Four of them became cyclonic storm in Bay of Bengal and were named, against a normal of five to six.^[1]
