A23L:
Mesoscale and Severe Convective Storms: Understanding, and Model Development and Evaluation I Posters


Submit an Abstract to this Session


Session ID#: 46885

Session Description:
Mesoscale convective systems (MCSs) are significant rain-producing weather systems over the globe. Severe convective storms (SCSs) produce large hail, damaging winds and/or tornadoes, and torrential rainfall, causing substantial damages. Quite often, SCSs are associated with MCSs particularly at the mid-latitudes. The physical understanding about factors impacting the initiation, intensity, and evolution for both MCSs and SCSs are still low. Model simulations of them are challenging particularly in global models. This session invites recent studies that use observations and/or model simulations at various scales to improve our understanding and model simulations of MCSs and SCSs. The efforts in parameterization development and model evaluation from cloud-resolving models to global models with various observational data are particularly encouraged.
