On the possible mechanisms of the evolution of a mini‐warm pool during the pre‐summer monsoon season and the genesis of onset vortex in the South‐Eastern Arabian Sea

During the pre‐summer monsoon season (February‐May), the near‐surface waters in the Arabian Sea progressively warm up and a mini‐warm pool with a core >30°C is manifested in the south‐eastem region. the possible mechanisms for the observed seasonal build‐up of this mini‐warm pool are examined, utilizing all the available monthly mean climatologies of surface wind field, surface heat fluxes, near‐surface thermohaline fields, near‐surface circulation, and mean sea level as monitored by satellites and by some of the recent model solutions on the Arabian Sea circulation.
