Centre to introduce advanced weather forecast systems in Noida, Pune
NEW DELHI : The ministry of earth sciences plans to set up two high-performance computers (HPCs) in Noida and Pune to enhance weather forecasting accuracy, in the face of shifting weather patterns leading to increasing instances of extreme rainfall. “None of the weather prediction models anticipated the 90cm rainfall witnessed in the Kayalpatnam municipality in Thoothukudi district of Tamil Nadu last week. Prediction of weather in tropical regions is difficult because of dynamic changes it undergoes in comparison to weather in higher latitudes," earth sciences secretary M.
Ravichandran told reporters in Delhi after unveiling the new logo for the India Meteorological Department (IMD), which will mark its 150th anniversary next month. “It is not the Indian (forecasting) model we are looking at. We are looking at a suite of models from Europe, US, India and Japan.
None of the models could capture this type of process. This is because of the sea nearby and the sudden developments. To do forecasts well in advance, we need more observations, a better understanding of present weather pattern changes and a high-resolution model to run, for which more HPCs are required.
In 2024 we will install two HPCs, which will be of high-resolution, while providing coverage of 6km from the existing 12km. One will be stationed in Pune and the other in Noida. These will allow us to predict widespread or extreme rain within 6 ks," Ravichandran added.
Kiren Rijuju, earth sciences minister, said they have a technology to ensure artificial rain, using the cloud seeding method, but will use it only in extreme circumstances. Such experiment could hurt climate for other parts. But the government has made it clear that over the next five years, the
