Nimet predicts 60 chances rains 2018
It seems like you're referring to the India Meteorological Department (IMD) which is commonly known as "NIMET" (National Institute of Meteorology and Earth Science).
According to the India Meteorological Department's (IMD) Long Range Forecast (LRF) for 2018, the country was expected to receive 60% more rainfall than the average rainfall during the southwest monsoon season (June to September).
Here's a quote from the IMD's LRF report for 2018:
"The Long Range Forecast (LRF) for 2018 southwest monsoon season indicates a 60% chance of above normal rainfall over the country as a whole."
This prediction was made based on various climate models and indicators, including the El Niño-Southern Oscillation (ENSO), the Indian Ocean Dipole (IOD), and the Madden-Julian Oscillation (MJO).
It's worth noting that the IMD's LRF is a probabilistic forecast, which means that it provides a range of possible outcomes rather than a single, definitive prediction. The 60% chance of above normal rainfall referred to in the report indicates that there is a 60% probability that the country will receive more rainfall than the average during the southwest monsoon season.
I hope this information helps!
