National Centre for Medium Range Weather Forecasting

The National Center for Medium Range Weather Forecasting (NCMRWF) was established in December 1988 by the Government of India as a mission mode project under Department of Science & Technology mandated to develop operational Numerical Weather Prediction (NWP) system for forecasting weather in the medium range (3-10 days in advance) scale and setting up of Agro-meteorological Advisory Service (AAS) units in the 127 agro-climatic zones spread all over India. Following were the main objectives.

  • Development of global and regional scale numerical weather prediction (NWP) models for forecasting weather in medium range (3-10 days)
  • Set-up a state-of-the-art supercomputing infrastructure to develop suitable NWP models to issue medium range weather forecasts
  • To inform and guide the farmers in advance to undertake various farming activities based on the expected weather
  • Set-up agro meteorological advisory service (AAS) units, each unit representing one of the 127 agro climatic zones spread all over India, to prepare/ issue/ disseminate AAS Bulletins based on weather forecasts and to provide user feedback as well

The Centre maintains high-end computing resource and regularly upgrades it to meet the above objectives. At present computer systems include a 32-processor CRAY SV1, 16 nodes(64-processors) indigenous PARAM PADMA system, 4-processor ORIGIN200 systems, a DEC-ALPHA distributed memory architecture based parallel system.

The NCMRWF strives to improve the accuracy, and consistency of its operational forecasts. The current focus is on development of seamless forecast system. Understanding and prediction of monsoon and high impact weather systems are major areas of R&D at the NCMRWF. The NCMRWF presently has a dedicated team of about 30 scientists to accomplish the goals. They have published more than 100 papers in the international and national journals, and have contributed nearly 200 papers in the proceedings of symposia and seminars. More than 50 Internal research/technical reports have also been published. Scientists of the Centre have contributed significantly to the development of global and regional numerical prediction systems within the country.

A number of global, regional and meso-scale numerical forecast models are being run in real time by the Centre. These are:

Global Models: T-80/L18 - horizontal resolution of 150 km and T-170/ L28 with 75 km horizontal resolution
Embedded Regional Spectral Model : 50 km grid resolution
Meso-scale Models: (i) MM5 with 30 and 10 km resolution; (ii) ETA Model with 48 km resolution

Agro-meteorological Advisory Service (AAS) and Forecasts to other users
The main objective of NCMRWF is to provide medium range weather forecast based AAS to the farmers of the country. The NCMRWF is providing AAS on experimental basis to the farming community, at the scale of Agro climatic Zones, based on location specific medium range weather forecast. The country is divided into 127 agro?climatic zones with each zone covering about 3?5 districts. At present NCMRWF has established AAS units in 107 agro climatic zones. Agromet Advisory Bulletins comprising of expert advise on crop, soils and weather are made available to the farming community through media and direct contact.

The location specific forecasts valid for 4 days comprising of six meteorological variables, viz., total precipitation, average cloudiness, average wind speed, predominant wind direction, maximum temperature and minimum temperature are derived NWP model outputs. These forecasts of weather elements are subjected to fine tuning through statistical and synoptic techniques to obtain final location specific weather forecast. They are disseminated biweekly to AAS units on every Tuesday and Friday over Telephone, Fax or Internet system. In addition to these parameters, forecast for weekly cumulative rainfall is also sent.

NCMRWF provides numerical weather predication (NWP) guidance to various user agencies including the India Meteorological Department(IMD) and NWP based forecasts to various sectors in the country. These include: Defence, Adventure, Tourism, Power, Agriculture, Water Resources, Fisheries, Space, etc. The NCMRWF issues forecast to Ministry of Agriculture a week in advance for weather condition likely to be experienced in different parts of the country. This is being used to assess the whole gambit of agricultural operations viz., crop, seed, fertilizers, insecticide situations in the country and accordingly forewarn concerned State Governments and other agencies with suitable remedial actions. NCMRWF has been issuing tailor made forecasts of winds, temperature and precipitation for Indian Army mountaineering expeditions, beginning from Everest Expedition-2001,Annapurna Expedition-2002, Everest-Lhotse Expedition-2003 and recently concluded Everest Expedition of 2005. During March 2003, NCMRWF issued forecasts to Indian Army Trans-India Hot Air Balloon Expedition. All these forecasts were found to be extremely useful by the respective event organizers and contributed significantly to the successful completion of these adventurous expeditions as proclaimed by these institutions. Forecasts are also issued to Power Grid Corporation of India Ltd (PGCIL) for power distribution purposes, ISRO for launching of space vehicles, State Governments for Pilgrimage purposes, etc.
