Doppler Weather Radar - METNET - India Meteorological Department

1. System generates hail, thunderstorm and dust storm warning symbols at the places likely to
get affected by hailstorm, thunderstorm, and dust storm using reliable warning
algorithms.
2. System is having capabilities of evaluating speed and direction of movement of weather
systems (track forecasting products).
3. System is also having capabilities of warning, if any, of the conditions defined by the user
are reached or fulfilled on reflectivity, velocity, VIL and wind shear.
4. System is having ability to detect tornado and gust fronts associated with storms and issue
visual and text warning message.
5. The system is able to generate a storm relative velocity product e.g. PPI, PCAPPI removing
the bias of storm motion velocity.
6. The system is capable of providing interactive method for locating storm centre,
superimposing 5°, 10° or 15° soft spiral overlay as per operator’s choice over the
reflectivity image containing spiral bands of the storm. The system is also able to measure
the radius of maximum wind within user defined grid of 5 – 60 km around the storm centre.
B.3.7. Alphanumeric products
The system is also be able to provide data on Reflectivity (Z), Radial velocity (V) and Horizontal
wind velocity, Rain rate in terms of latitude and longitude and heights at user defined height grid
point up to 200 km from radar site in tabular form for ingesting these data into numerical models
for weather predictions, however this facility does not configured in the M/s Metstar DWRs.
B.4. Workstations and display capabilities of the system
B.4.1. Workstations
The WSR98-D/S system is having seven nos. of workstations, as detailed giving below to
perform various tasks of data acquisition, product generation, archival, display and house
keeping. Workstation is based on same hardware platform.
i. Two workstations with identical features having 21″ LCD color monitor (one main and the
other as hot standby) for control and operations involved in data acquisition, product
generation, product display and archival.
ii.
iii.
iv.
One workstation with 21″ LCD color monitor for maintenance, calibration and house
keeping tasks.
One workstation with 29″ LCD color monitor for simultaneous real time display of Z, V, σ
and BITE parameters
One workstation with 21″ LCD color monitor for collecting products, networking and
dissemination of products over internet.
