Scope Volcanic eruption clouds (eruption column, pyroclastic flow, and umbrella cloud) and cumulonimbus are similar phenomena in the atmosphere; they behave as a buoyant plume or gravity current whose driving force is buoyancy. The spreading of eruption clouds leads to the fallout of volcanic pyroclasts, whereas the cumulonimbus results in the precipitation. In general, observed data of eruption clouds reflect the source conditions at the vent, and those of cumulonimbus reflect the environmental conditions. The models that can precisely reproduce the physical processes in such phenomena and the accurate observations have been required. In this session, we will discuss the modelling and observations of eruption clouds and cumulonimbus from the viewpoint of meteorology, volcanology, and remote sensing. The approaches from laboratory experiments, sedimentology and material sciences are also welcomed.
