Response of sea state to the monsoon onset

Utilizing the buoy meteorological data of Arabian Sea collected during onset phase ARMEX an attempt has been made to examine influence monsoon 2003 on surface parameters. The peaking and collapse warm pool compared with normal conditions it found that was very gradual. As a matter fact evaporative cooling in region quite subdued which shows sudden should be expected occur only when vortex is formed did not happen 2003.The roughness sea (wave height) increased over southeastern about 2-3 days before showing swells are reliable precursors onset. There steep fall SLP throughout eastern (8° - 20° N) week Kerala 8 June. All buoys from DS7 SW1 registered this type change. After 1 June SLPs remained almost steady unimpacted by or subsequent advance along west coast.
