Understanding Monsoon Onset over Bay of Bengal

Occurrence of Super Cyclones

during monsoon onset period

One example of MOMSEI Science Application

Identify local concerns through Pilot Study

• Myanmar: cyclones, extreme rainfall

• Thailand: internal waves, OMZ, coral bleaching

• Malaysia: cold surge, floods

• Indonesia: upwelling/fishery, wet/dry transition

• China: flood/drought

Developing comprehensive science plan

MOMSEI Learning Curve through its Pilot Study

• Core scientific question:Why does monsoon firstly onset over BoB?How does Malaysia experience distinct monsoon from its neighborhood?How does Indonesian-Australian monsoon onset?

• Social focus: Flood/Drought associated with monsoon anomalies---- Support the regional monsoon outlook forum in line with GFCS

• Ecosystem Impact:Coral bleaching associated with late monsoon onsetOxygen Minimum Zone and its impacts on coastal regionUpwelling associated with monsoon forcing and linkage to fishery

Red: Initial MOMSEI ideas

Blue: Extended MOMSEI ideas after pilot study

Summary

• Monsoon onset really matters• Asian Monsoon firstly onsets over BoB/AS• Monsoon onset science still weak• Monsoon onset favors the super cyclone

• MOMSEI, through its network in observation, capacity building and target research, aims to further improve our understanding of the complex monsoon system
