Abstract: Miyakejima plumes of ash-rich and vapour-rich clouds were detected well by the NOAA/AVHRR data, and the height of eruption cloud on 29 August 2000 was estimated reasonably using the brightness temperature at 11 µm of NOAA/AVHRR and the upper air data taking into account the effect of ash emissivity. We found two different mechanisms which bring the high concentration SO₂ to the mainland of Japan: convective daytime mixing brings gas down to the surface, after advection from Miyakejima in the upper air by winds associated with high pressure system; and the volcanic gas descends to the island surface in strong winds associated with stationary fronts and low pressure systems.
