- India’s average mean monthly temperatures were “warmer than the normal” during all the months of the year except December.
- This more than normal mean monthly temperature is attributed to global warming.
- The annual mean surface air temperature averaged over the country in 2018 was +0.41 degree Celsius above (1981-2010 period) average.
- The year 2018 was the sixth warmest year on record since nationwide records commenced in 1901.

- The worrying factor is, 11 out of 15 warmest years were during the recent past 15 years (2004-2018) and overall 2018 was the sixth warmest year on record since nationwide records commenced in 1901.
- India recorded 1,428 deaths in 2018 due to extreme weather events and heavy rains and subsequent flooding, dust storms, thunderstorms and lightning claimed half the lives.

India Meteorological Department (IMD)
India Meteorological Department (IMD) is the chief government agency for meteorological services in the country. Formed in 1875, IMD functions under Ministry of Earth Sciences and is headquartered in New Delhi. It deals with everything related to meteorology, seismology and associated subjects like
- Undertaking meteorological observations and provide current information and forecasting information for most favourable operation of weather-dependent activities such as irrigation, agriculture, aviation, shipping etc.
- Offering warnings against severe weather phenomenon such as tropical cyclones, norwesters, dust storms, heat waves, cold waves, heavy rains, heavy snow, etc.
- Providing met-related statistics needed for agriculture, industries, water resources management, oil exploration, and any other strategically important activities for the country.
- Engaging in research in meteorology and allied subjects.
- Detecting and locating earthquakes and evaluate seismicity in various parts of the country for developmental projects.
From a modest beginning in 1875, IMD has progressively expanded its infrastructure for meteorological observations, forecasting and weather services. IMD was the first organisation in India to adopt a message switching computer to support its global data exchange.
The India Meteorological Department (IMD) has stated that cyclone Pabuk will move northwestwards and cross the Andaman Islands late on 6th Jan as a cyclonic storm with wind speed up to 90 kmph. IMD has sounded a orange alert for the cyclone Pabuk. The Pabuk cyclone would cause heavy rain over the Andaman Islands.
Cyclone Pabuk originated over the Gulf of Thailand and neighbourhood. The IMD predicts that Pabuk would move west-northwestwards and emerge into the Andaman Sea. Then it would move northwestwards and cross the Andaman Islands. Then recurve northeastwards towards Myanmar coast and weaken gradually.
The four stages of cyclone warnings in India are:
- The First Stagewarning Pre Cyclone Watch, issued 72 hours in advance. It contains an early warning about the development of a cyclonic disturbance in the north Indian Ocean, its likely intensification into a tropical cyclone and the coastal belt likely to experience adverse weather.
- The second stage warning is Cyclone Alert, is issued at least 48 hrs in advance of the expected commencement of adverse weather over the coastal areas. It contains information about the location and intensity of the storm likely direction of its movement, intensification, coastal districts likely to experience adverse weather and advice to fishermen, the general public, media and disaster managers.

- The Third Stage warning is Cyclone Warning, issued at least 24 hours in advance of the expected commencement of adverse weather over the coastal areas and the landfall point is forecasted at this stage.
- The Fourth Stage of warning is Post Landfall Outlook and it gives likely direction of movement of the cyclone after its landfall and adverse weather likely to be experienced in the interior areas.
Even though there is no cyclonic situation for Odisha, Seven districts of Odisha have been put on alert and the weather in Odisha would be cloudy and dry.
