The computing power and modeling of weather is not an easy task.
BEL used to make Cyclone tracking Radars in late 69/70s. We need whole bunch of PARAM power to improve.
By the way has mansoon arrived in Kerala, so that there may be hope of relief in Hyderabad in two weeks after that.

Chinese firm to set up weather radars in India
New Delhi: A Chinese hi-tech firm will build and install 12 doppler weather radars, or DWRs, at important Indian ports and cities including the national capital and Mumbai.
Beijing Metstar Radar Co. Ltd, a venture of China National Huayun Technology Development Corp., a wholly-owned subsidiary of the China Meteorological Administration, and US-based Lockheed Martin Corp., outbid Bharat Electronics Ltd, which develops weather radars based on proprietary technology of the Indian Space Research Organisation, and Germany’s Selex Gematronik GmbH, for the contract to install the radars that was awarded by India Meteorological Department, or IMD, on 30 May.
Industry experts say this would make it one of the rare high technology imports from China into India.
“I am not sure it is the first, but definitely one of the first and certainly very important,” said T.S. Vishwanath, who heads the trade policy division of the Confederation of Indian Industry—an industry lobby. “Bilateral trade is dominated by raw materials, and this could pave the way for good quality, affordable technology trade between the two countries.”
Changing climate: The Chinese firm will install 12 doppler weather radars.Bharat Electronics and Selex Gematronik have previously commissioned weather radars in the country.
However, there are some apprehensions within IMD itself.
“While our technical evaluation company is certainly competent, I hope they have not compromised on quality for cost,” says an IMD scientist not connected with the technical evaluation and selection of firms to supply the radars and who didn’t want to be named.
Without commenting specifically on the deal, IMD chief Ajit Tyagi says IMD will only procure equipment “as per its specific requirements and will never compromise on quality”.
Former IMD chief R.C. Bhatia says these DWRs are of high quality. “The Metstar radar is an upgraded version of the US’ NEXRAD weather radar systems, which is being actively used by the (US) government for their own forecasting systems,” he pointed out.
Metstar radars have been built based on the weather radar technology acquired from Lockheed Martin. Metstar has supplied similar radars for China, Romania and Korea.
“Lockheed Martin is involved and supports international sales of doppler radars, but (it) no longer internationally bids for contracts that involve only the supply of doppler weather radars, having transferred the LM-derived technology to Metstar in the mid-1990s,” Lockheed Martin says in an emailed statement. “Rather than bid directly, Lockheed Martin currently routes all requests like that to Metstar.”
The DWRs, to be set up at Mumbai, Delhi, Agartala, Mohanbari, Paradip, Bhopal, Nagpur, Patna, Lucknow, Karaikal, Patiala and Goa, will be supplied, installed and commissioned by Metstar for about $17.8 million, or about Rs76 crore.
Doppler weather radars have an edge over other weather radar systems because they can measure the speed of a storm or cyclone. The radars the government uses right now provide information only on the range of a storm whereas a DWR system provides data to accurately estimate an approaching storm’s centre and intensity, fixing its position and predicting its path.
“Now it’s DWRs everywhere. Nobody really uses ordinary weather radars,” Tyagi says.
This contract is part of a Rs900 crore modernization plan by IMD, a major part of which involves upgrading weather forecasting equipment. The agency plans to install a network of 55 DWRs, of which 12 will be commissioned by Metstar in the first phase.
Along with DWRs, IMD is also buying 550 automatic weather stations and 1,350 automatic rain gauge, or ARG, stations, as part of a plan to move into numerical weather prediction, which is globally used to give precise weather forecasts, as opposed to statistical techniques still being used in India for monsoon forecasts.
Meanwhile from ISRO web Site this dated May 1st 2008 ( Mera Bharat Mahan

A Memorandum of Understanding was signed today (May 1, 2008) by the Indian Space Research Organisation (ISRO) with Snow and Avalanche Study Establishment (SASE) of the Defense Research and Development Organisation (DRDO) for the installation of two Doppler Weather Radars in the Himalayan region for climate studies. ISRO has indigenously developed the technology of Doppler Weather Radar and transferred it to Bharat Electronics Ltd for the production of these radars. Doppler Weather Radar (DWR) operates in S band and is capable of monitoring clouds, precipitation systems and winds over large areas of more than 400 km from the radar location. DWR has the unique capability to continuously track and predict fast evolving weather systems such as thunderstorms, cyclones and cloudbursts. The first such indigenous radar is operating at Sriharikota since April 2004. The Mark II version of DWR which is under production is a state of the art system with performance comparable with radars available elsewhere. DWR development called for high-end electronics, advanced data processing techniques and software for product generation.
As per the MOU signed today, two Doppler Weather Radars with advanced polarimetric capability will be established in the Himalayan region to monitor critical climate parameters including snowfall and help in improved weather forecasts for high altitude operations. The data from DWRs will be useful for the study of monsoon dynamics, avalanche prediction, detection of clear air turbulence and tracking of cloud burst, hailstorm and other severe weather events. In view of the global warming scenario, it is of paramount importance to monitor the highly sensitive and climatically unique Himalayan terrain.
ISRO is also installing two DWRs in the North East region of India to support Disaster Management by aiding the early warning of floods, landslides and other severe weather events. The Indian Meteorological Department is already procuring two such radars from BEL for installation at Kochi and Bhuj for cyclone monitoring.
So there we are build, buy or delay ( mansoons
