[M-IS02] [EE] Dynamics of eruption cloud and cumulonimbus; modelling and remote sensing

Wed. May 24, 2017 3:30 PM - 5:00 PM Poster Hall (International Exhibition Hall HALL7)

convener:Eiichi Sato(Meteorological Research Institute), Yujiro Suzuki(Earthquake Research Institute, The University of Tokyo), Fukashi Maeno(Earthquake Research Institute, University of Tokyo), Takeshi Maesaka(National Research Institute for Earth Science and Disaster Prevention)

The 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, the 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, volocanology, and remote sensing. The approaches from laboratory experiments and material sciences are also welcomed.
