SASCOF

IMD has taken responsibility for the preparation of annual regional forecast outlook for the SW Monsoon Season rainfall under the regional forum known as the South Asian Climate Outlook Forum (SASCOF). The idea of establishing SASCOF was originated in a meeting convened by WMO, the Directors General of the National Meteorological and Hydrological Services (NMHSs) in South Asia and Permanent Representatives (PRs) of the respective countries with WMO, at the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy, on 6 August 2009. The PRs of south Asian nations with the WMO had unanimously agreed to implement SASCOF for southwest monsoon season from 2010 onwards. The first three (during 2010-2012) and fifth (during 2014) meetings of SASCOF was hosted by India Meteorological Department and held at Pune. The fourth session (in 2013) of the SASCOF was held at Kathmandu, Nepal and sixth session (in 2015) was held at Dhaka, Bangladesh. SASCOFs are generally conducted during the 3rd week of the April month each year. The main activity during all the SASCOFs was the preparation and issuing of a consensus outlook for the southwest monsoon rainfall over South Asia. Associated with last 5 SASCOFs, Training workshops on seasonal prediction were also held.

ABOUT NCC

National Climate Centre (NCC), Pune which was established in 1995 by India Meteorological Department (IMD) with an objective to provide various climate related services to the country (India). NCC has been carrying out many India specific climate related activities like Climate Monitoring and Analysis, Climate Data Management, Climate Research and Climate Prediction (Seasonal Forecasts). NCC is bringing out climate diagnostic bulletins regularly and different climate data products are prepared for the user community. Operational Seasonal forecast for rainfall over the country is another important activity of the NCC.
From May 2013, NCC has started to work as WMO recognized RCC (Pilot Phase) for the south Asia. For this, NCC started to prepare several climate monitoring and long range forecast products for south Asia. These products include monthly and seasonal rainfall and 2m temperature anomaly maps for the south Asia, season forecast outlook for temperatures and rainfall for south Asian countries, ENSO and IOD forecast bulletin etc. These products are updated every month.

Extended Range Forecast

The extended range forecasting (forecasts between 7 and 30 days) fills the gap between medium-range weather forecasting and seasonal forecasting. It is often considered a difficult time range for weather forecasting, since the time scale is sufficiently long so that much of the memory of the atmospheric initial conditions is lost, and it is probably too short so that the variability of the ocean is not large enough, which makes it difficult to beat persistence. Since the Madden Julian Oscillation (MJO) is the most important mode of tropical intraseasonal variability with potentially important influences on the monsoon activity in the Asian regions, the capability of statistical or numerical models in capturing MJO signal is very crucial in capturing the active/break cycle of monsoon.

High-resolution simulations of 20th century climatic variations and future climate projections

Have been developed at CCCR-IITM, using a global climate model with telescopic zooming (~35 km in longitude x 35 km in latitude) over the South Asian region. These high-resolution simulations, which were performed on the PRITHVI High Performance Computing (HPC) facility at IITM, offer new opportunities to better understand several key regional scientific issues concerning climate change over South Asia - e.g., Monsoons, precipitation extremes, heat waves, droughts and floods, changes in cyclonic weather systems, hydrological cycle etc. ( For More information : Click here )

Reanalysis Data Services

The Indian Monsoon Data Assimilation and Analysis reanalysis (IMDAA) is a regional atmospheric reanalysis over the Indian subcontinent. The IMDAA is the result of collaboration among the Met Office (MO), U.K, National Centre for Medium Range Weather Forecasting (NCMRWF), India and the India Meteorological Department (IMD) with funding from the National Monsoon Mission (NMM) project of the Ministry of Earth Sciences, Government of India. This data web portal contains (1) IMDAA Data - high resolution (12km, 1-hourly) regional reanalysis over India, from 1979 to 2018 and (2) NGFS Data - high resolution (25km, 6-hourly) Global reanalysis, from 1999 to 2018.
