Under the BOBBLE (Bay of Bengal Boundary Layer Experiment - BoBBLE), the Indian Science Institute of Bangalore and the University of East Anglia of the United Kingdom have jointly formed an action plan for accurate forecasting of monsoon, tropical cyclones and weather.
What is BOBBLE
BOBBLE is a joint India-United Kingdom project that examines the impact of oceanic processes operating in the Bay of Bengal on the monsoon system.
Finance for this project is provided by the Ministry of Earth Sciences of India and the Natural Research Council of the United Kingdom.
It is known that the Bay of Bengal plays a fundamental role in the context of the monsoon in the South-Asian region.
Main Processes Running in the Bay of South Bengal
The southwest monsoon current is a major stream controlling salt and sea surface temperatures in the Bay of Bengal which is itself controlled by local (wind pressure curl) and remote (equatorial wave propagation) factors. . This stream is related to the change in weather over a wide area of the Indian Ocean.
The excess of salt in the south-west monsoon stream is due to the western equatorial Indian Ocean, which is connected to the Bay of Bengal through the Somalian stream, the equatorial current and the southwest monsoon stream.
Seasonal changes at the Somalian stream and southwest monsoon stream junctions act as railroad switches and divert waterfowl to the different valleys of the North-Indian Ocean.
How much Chlorophyll in the Bay of South Bengal is determined directly by the mixed layer processes and the strength of the barrier layer.
What is monsoon?
Monsoon occurs in these regions - Indian subcontinent, South-East Asia, parts of Central-West Africa etc. In the Indian monsoon there is a large amount of heat convection.
The monsoon is associated with every second to seventh year event like El Nino and La Lina.
