Context:A team from IISC,Bengaluru and UK based University of East Anglia have recently created a blueprint for accurate prediction of monsoon, tropical cyclones and other weather related forecasts under the project BoBBLE.
The BoBBLE(The Bay of Bengal Boundary Layer Experiment):
- It is a project funded by the Union Ministry of Earth Sciences and the Natural Environment Research Council of UK.
- BoBBLE will deploy two ships, six ocean gliders and eight floats to collect an unprecedented range of oceanic and air-sea flux observations.
- BoBBLE scientists will analyse these observations, along with routine datasets, to understand the evolution of conditions in the Bay and how they influence the atmosphere.
- The researchers from a number of other institutions of repute from Kerala, Goa, Visakhapatnam and Hyderabad were part of the project.
- After the studies a blueprint for future weather system observational experiments was created for accurately forecasting rainfall.
Significance of the project:
- Accurate weather forecasts:
- The Indian monsoon (June-September) provides 80% of the annual rainfall for over one billion people, many of whom depend on monsoon rains for subsistence agriculture and freshwater.
- It is critical to forecast accurately not only the seasonal rainfall, but also rainfall variations within the summer.
- Well-represented air-sea interactions in the BoBBLE:
- Although air-sea interactions are important to the monsoon, weather predictions are currently made with models of only the atmosphere.
- There is potential to improve monsoon forecasts by including well-represented air-sea interactions in models.
Retrospective forecasts of the BoBBLE period with atmosphere-only and atmosphere-ocean coupled models will demonstrate how air-sea interactions influence monsoon rainfall predictions.
