HISTORY
The old observatory was established in Nagpur since 1869 at Mayo hospital
premises. Meteorological office at Airport Nagpur was established in the year 1947 as a
class–I observatory. It was further enhanced to Regional Meteorological Centre from 1st
April 1954 and was shifted to new RMC Building opposite to Airport Terminal building.
Earlier RMC Nagpur had only one State Meteorological Centre at Bhopal, but after creation
of Chhattisgarh state, a new Meteorological Centre at Raipur was established in April, 2001.
It covers overall maintenance of observatories in Vidarbha, Madhya Pradesh and
Chhattisgarh.
NWP Product Rainfall & Wind forecast
2. Digital Met Data Dissemination System. The meteorological data are transmitted to different
Met. Centres through satellite based Digital Met Data Dissemination (DMDD) equipments.
The process remains unaffected by adverse weather condition.
4. High Speed Data Terminal (HSDT) is used to transmit and receive met data. The system is
connected through VPN to the AMSS in Mumbai and RTH New Delhi. All met data can
be accessed at HSDT using the Met Connect software interface.
5. www.imdnagpur.gov.in is RMC Nagpur website for online weather information.
DMDD Equipment
3. Synergie Software for advanced weather forecasting. The system has been acquired from
Meteo France International (MFI). Digital data & images are fed into central server as
input & are disintegrated and processed to run numerous weather models.
6. IVRS system for weather on phone (Nagpur tel.nos.0712- 2294291, 2294292, 2294293,
2294296. Raipur tel. nos.0771- 2419248, 2419249. Bhopal tel.no.0755-2551523,
2551524) has been started in 2008 in the region.
WEATHER FORECASTING
Daily inference is issued at 12 hours noon, based on 03 UTC (0830 hours IST) data
which contains synoptic features, forecast for the region for next 2 days, Heavy Rainfall
warnings, position of the weather system if any, local forecast for city of Head Quarters and
Outlook for subsequent 2 days along with the summary of weather phenomena occurred (Daily
weather report). These bulletins are issued from Nagpur for entire central parts of the country
comprising Vidarbha, MP & Chattisgarh; from Bhopal for MP and from Raipur for Chattisgarh
state.
Apart from this, weekly bulletin (Weekly Weather Report) is also issued on every Thursday
which contains weather summary of previous week (Thursday to Wednesday).

Met. Support is also provided at Bhopal, Raipur (Mana), Indore, Gwalior, Khajuraho
and Jabalpur Airports.
HEAVY RAINFALL & SEVERE WEATHER WARNINGS
Warnings for Heavy Rainfall and other severe weather like heat-wave, cold–wave,
approaching low pressure system are disseminated well in advance to all concerned.
REGIONAL DATA SUPPLY
Daily, monthly and yearly meteorological data of observatories in Vidarbha, MP and
Chattisgarh are supplied from Climatological unit of RMC Nagpur to different users.
DOPPLER WEATHER RADAR (DWR)
State of the art S-band Doppler Weather Radar of M/s Metstar Ltd. (China) make
is capable of weather surveillance up to 250km (maximum up to 500km) around Nagpur. It
provides imageries derived from volume scan depicting location and intensities of clouds,
expected rainfall from these clouds, horizontal winds, wind shear etc. The imageries are a
very good tool for weather analysis, forecasting and nowcasting. The Radar products are
automatically updated to IMD’s website regularly.
DWR PPI Imagery: 500km Around Nagpur
DWR Building Nagpur
DWR Rainfall imagery: 250Km around Nagpur
AGRICULTURAL ADVISORY BULLETINS
In 1932, a special division of Agricultural Meteorology was created with headquarters
at Pune. The Farmer’s Weather Bulletin (FWB) system was started for farmers in 1945 in
the department and Agro Meteorological Advisory Unit was established in 1987 to extend
meteorological services to the farming community in the region.
Agro Meteorological Advisory Units at RMC Nagpur for Vidarbha, at Bhopal for
Madhya Pradesh and at Raipur for Chhattigarh are regularly issuing Bi-weekly Agromet
Advisory Bulletins on every Tuesday and Friday in co-ordination with the State Agricultural
Universities and State Agricultural Dept., Maharashtra, Madhya Pradesh and Chhattisgarh
for the benefit of the farming community in the region.
These units issue Bi-weekly District weather forecast valid for succeeding five days for
the 3 Agro-Climatic Zones in Vidarbha, 9 Agro-Climatic Zones in M.P. and 3 AgroClimatic Zones in Chhattisgarh covering all the 11 districts in Vidarbha, 50 districts in M.P.
and 18 districts in Chhattisgarh in co-ordination with Panjabrao Krishi Vidyapeeth, Nagpur
and different Agricultural Universities in M.P. and Chhattisgarh. This Unit also issues Biweekly Bi-Lingual Agro-meteorological and Agriculture Bulletins on Tuesday and Friday in
collaboration with the State Agriculture Departments.
The bulletin reflects the Significant past weather phenomena prevailed and the relative
forecast. The state Agriculture departments provide the inputs regarding Crop condition
along with the Pests & Diseases and remedies to be followed to prevent them. The AgroMet Field Units of Universities provide the weather based Agro-advisories.
Proposed 55 DW Radars’ network in India
These bulletins are transmitted to electronic and print media viz. AIR, Doordarshan and
newspapers for the benefit of farmers and other user agencies in the region.
Following are important phone numbers to have various meteorological information of
places under Regional Meteorological Centre, Nagpur comparises of Vidarbha, some part of
Marathwada, Madhya Pradesh and Chhattisgarh.
