Weather Forecasting Accuracy in India: Challenges and Insights
The India Meteorological Department (IMD) is India's main weather and climate agency, established in 1875.
They try to predict the weather, but it's hard!
Their goal is to predict weather perfectly for a few days and mostly accurately for a longer period.
The article talks about how accurate weather forecasts can be, especially for things like farming.
One main problem is that the weather is super complicated; a small change can have huge effects, like the "butterfly syndrome."
The IMD is also getting new technology to study dangerous storms like cyclones, which should help them get even better at weather predictions.
India Meteorological Department (IMD) was established in 1875 for weather observation, forecasting, and climate monitoring.
IMD aims for zero-error forecasts for up to three days and 90% accuracy for five-day forecasts.
The article discusses the challenges of accurate weather forecasting, especially at the local level.
IMD is acquiring technology used in other countries to study cyclones by sending aircraft into their eyes.
The author notes the limitations of weather forecasts due to unpredictable factors like the "butterfly syndrome."
