[M-IS13] Dynamics of eruption cloud and cumulonimbus; modelling and observation

Sun. Jun 6, 2021 5:15 PM - 6:30 PM Ch.19

Volcanic eruption clouds (eruption column, pyroclastic flow, and umbrella cloud) and cumulonimbus are similar phenomena in the atmosphere. Models that can precisely reproduce the physical processes in such phenomena, and accurate observations have been required. Recently, the development of remote sensing techniques such as weather radar and weather satellite are remarkable, and they are being adopted for volcanic eruption monitoring. However, it is indispensable to verify the results of modeling and remote sensing using in-situ observations. In this session, we will discuss the modelling and the observations of eruption clouds and cumulonimbus from the viewpoint of meteorology, volcanology, geology, and other related fields. The related phenomena such as ashfall, rainfall, snowfall, hail and volcanic block will also be discussed.
