- IMD has a large computer facility equipped with a CYBER
2000U System at RSMC New Delhi for supporting R&D activities
and to meet some of service obligations at the national and international
levels.
- CYBER is a mainframe computer that supports one processor. The
computer ethernet in Local Area Network (LAN) with the message switching
system in the Regional Telecommunication Hub for accessing GTS
data and also with satellite imagery data from IMD’s INSAT
Computer (IMDPS).
- The computer system is provided with a large number of standard
and utility software packages. The system’s main applications software
is a comprehensive meteorological graphics applications software (AMIGAS
II).
- Most of RSMC’s operational activities have been automated on
the CYBER computer. Plotting of all extended charts, both sea level
and upper air and various auxiliary charts is carried out on the attached
plotting machines.
- A Limited Area Analysis Forecast System (LAFS) comprising automated
decoding of observational data received on GTS, an objective analysis
scheme based on three multivariate optimum interpolation procedure
and an advanced multi layer primitive equation model runs on the
CYBER system in operational mode daily twice a day.
- Analyzed and prognostic charts produced by the LAFS are transmitted
to other centers as a part of RSMC New Delhi’s responsibility under
World Weather Watch. The forecast model is also used for giving tropical
cyclone track predictions.
- Besides RSMC products from the LAFS, grid point data received
from world Area Forecast Center Washington/Brackne11 are also processed
for preparing documentation charts for aviation purposes under the
world Area Forecast System.
