OBJECTIVES OF MODERNISATION Modernisation of atmospheric observation & forecasting systems was initiated to improve the quality of meteorological services in the country with focus on the following:

To enhance capabilities of observational systems To network all existing and new observational systems To enable reception, processing and archival in digital form To assimilate multi sector data in numerical models and

prediction To ensure real-time dissemination of all processed

information

As a part of this and in keeping with the guide–lines given by the Planning Commission, Secretary, MoES constituted an expert committee comprising of eminent scientists and experts in India under the chairmanship of Shri D. R. Sikka to specify the optimum requirements of the observational network required for Forecasting, Aviation Services, Agro-meteorology and human resource in the field of meteorology to provide a weather service of World Standard. The committee recommended the optimum observation network for IMD.

MODERNISATION OF IMD

It was proposed to implement the complete modernisation in three phases. In the first phase, it was approved to develop a network with minimum and necessary observation system consisting of existing and new instruments, appropriate connectivity with a complete end-to-end forecasting system along with High Performance Computing (HPC) for receiving, processing and archiving information at IMD Headquarters as well as their dissemination in real time to the end users in digital form. In next phases further densification of the observation network is to be undertaken. The commissioning of Doppler Weather Radars will start from the first phase but all 55 DWRs will spill over to 12

th five year plan as Phase III.

The Union Cabinet approved the implementation of Modernisation of observation and forecasting facilities of IMD (Phase – I) on 13

th December 2007, (to improve the weather

forecasting services in India) at an estimated cost of Rs.920.00 crores in two years. It has been further extended till March 2011 The Phase-I to be implemented in project mode and classified into broadly two groups: a) OBSERVATIONAL SYSTEMS

1. Doppler Weather Radars 2. GPS Radio Sonde Stations 3. New Optical Theodolites 4. Automatic Weather Stations and Rain Guages 5. Airport Met Systems 6. Wind Profiler 7. Lightening Detection 8. Indigenous development of Radio Sonde

b) NETWORKING, ANAYLSIS, DISSEMENATION 1. AMSS 2. Forecasting & other systems of MFI 3. HPCS

COMMONWEALTH GAMES FORECAST

Using the WEB-GIS tools hourly AWS data received through IITM and hourly location specific forecast were ingested and put on the IMD’s website http://202.54.31.51/cwg2010/.

Both the forecasted and current values of the important Met parameters like Temperature, Relative Humidity and Wind speed & wind direction were simultaneously made available. The GTS- AWS data was decoded and put online along with WRF hourly forecast (00Utc run) for 31 stations in and around Delhi .Furthermore hourly forecast was also made available at each grid point of 3X3 kms resolution, for the Delhi and surrounding region. The whole process of information flow of AWS data from GTS network and model products generated is online and time scheduled to be updated after every one hour and 24 hours respectively

Hourly Temperature profiles from WRF, for the month of October were generated . These profiles were generated directly using the netcdf output of the WRF model .The process has been automated using arcgis 9.1..Such hourly profiles for other met Parameters like rainfall can be generated as and when the model output is made available and would help to put the latest and current information online. Analyzing the warm and cold zones for Delhi and surrounding area can be studied using such profile. Plotting rainfall data along over Delhi would help us to study the impact of the rainfall event over various regions of Delhi

OBSERVATIONAL SYSTEMS

DOPPLER WEATHER RADARS

Installation completed Sites

Radar installation is complete in Mumbai, Agarthala and Nagpur. These locations will be commissioned shortly after undergoing Site Tests.

Installation completed Sites

Bhuj Patna Mohanbari The process of precise alignment during the installation determines the smooth operational capablities and in turn life of mechanical hardware. The installation is divided atleast in three stages for customarary procedures and phased evaluation. Photographs above indicates installation progress at Bhuj, Patna, and Mohanbari

Status of remaining sites The status of the remaining radar locations are: Patiala & Lucknow –Radar Installation in progress; Kochi - Ceiling work Terrace casting and equipment room finishing kept on hold in view of MoD’s advice for the following Paradip, Karaikal, Goa.

CWG-2010 Operational Nowcasting

First Doppler Weather Radar installed at Palam-Delhi, under modernization gave intensive support for the CWG – 2010. The data was used in real time analysis / nowcast as well as feeding into regional high resolution models (ARPS) and automated nowcasting tools (WDSS-II & SWIRLS). The figure aside shows the maual analysis performed during a discipating cell passage over Delhi on 7th October 2010.

During the entire event of the cumulus cell

passage, the radar was operated in a

different suitable scan tested prior, for a

detailed analysis.
