Short summary

To understand the circulation pattern in the Gulf of Thailand (GoT) and the local wind effect, satellite and in situ observations are used. The flow is highly variable at the western boundary and the GoT mouth. Seasonally, it is dominated by the monsoon winds and sea surface level set up by local wind rotation. Surprisingly, interannual variation in the current over each region in the GoT responds to different climate modes (El Niño–Southern Oscillation and the Indian Ocean Dipole) differently.
