It keeps round the clock watch over the North Indian Ocean and detects, tracks and predicts cyclonic storms
using numerical models for tropical cyclone track and intensity prediction.
It issues cyclone advisories 8 times a day to the panel countries of WMO/ESCAP.

The IMD also implements the Regional Cyclone Operational Plan of WMO/ESCAP Panel.
The National Disaster Response Force (NDRF) is tasked with carrying out rescue and relief operations under
the National Disaster Management Act 2005.
National Cyclone Risk Mitigation Project (NCRMP): This World Bank supported project aims to
undertake suitable structural and non-structural measures to mitigate the effects of cyclones in the coastal
states and UTs of India. The Project has identified 13 cyclone prone States and Union Territories (UTs) and
has classified them into two categories based on their vulnerability as follows: Category I: Higher
vulnerability States i.e. Andhra Pradesh, Gujarat, Odisha, Tamil Nadu and West Bengal. Category II: Lower
vulnerability States i.e Maharashtra, Karnataka, Kerala, Goa, Pondicherry, Lakshadweep, Daman and Diu,
Andaman and Nicobar Islands. National Disaster Management Authority (NDMA) under the aegis of Ministry
of Home Affairs (MHA) will implement the Project in coordination with participating State Governments.

Mobile Apps: 'Mausam' was launched by IMD to provide timely weather updates to the users.
'Meghdoot' app provides similar service in local languages to farmers for planning crops.
'Damini Lightning' provides lightning and thunderstorm forecasts and locations of occurrence.
What are Cyclones and how they are Named?

f Cyclones are caused by atmospheric disturbances around a
low-pressure area distinguished by swift and destructive air
circulation.
f Cyclones are usually accompanied by violent storms, bad
weather and storm surges along coastlines.
f Direction of air circulation: In the Northern hemisphere, the
air circulates inwards in anti-clockwise direction and
clockwise in the Southern hemisphere.
f Cyclones are classified as: (i) extra tropical cyclones (also called temperate cyclones); and (ii) tropical
cyclones (occurring between Tropic of Cancer and Capricorn).
f In India, cyclones are classified by strength of associated winds, storm surges and exceptional rainfall
occurrences.

f WMO criteria: The World Meteorological Organisation (WMO, 1976) uses the term 'Tropical Cyclone' to
cover weather systems in which winds exceed 63 km/h.

f Different names: Cyclones are called as 'typhoons' in China sea and Pacific Ocean, 'hurricanes' in
Caribbean Sea and Atlantic Ocean, 'tornados' in Guinea lands of West Africa and southern USA, 'Willy
Willies' in NorthWestern Australia
How Cyclones are named?
f RSMCs and TCWCs: Cyclones that form in every ocean basin across the world are named by the
Regional Specialized Meteorological Centers (RSMCs) and Tropical Cyclone Warning Centers (TCWCs).
There are six RSMCs in the world, including the India Meteorological Department (IMD), and five
TCWCs.
f In the Atlantic and in the Southern hemisphere (Indian ocean and South Pacific), tropical cyclones
