UP1.3Understanding and modelling of atmospheric hazards and severe weather phenomena
|Conveners: Fulvio Stel , Arne Spekat | Co-Conveners: Dario Giaiotti , Mario Marcello Miglietta , Sante Laviola , Jordi Mazon , Victoria Sinclair|
This session will welcome all technical and scientific contributions devoted to increasing our understanding of atmospheric phenomena that might represent a hazard for people, property and the environment. Studies which enhance physical understanding of severe weather phenomena (for example deep convection or intense straight lines winds) are of particular interest even if the severe weather phenomena is not linked directly to a specific hazard.
In line with the EMS 2018 meeting theme “Weather and climate: Glocal change and local hazards”, we would encourage potential contributors to direct their attention not only to the physical and meteorological characteristics of atmospheric hazards, but also to their relevance in a changing climate including possible impacts on human activities and the environment.
Contributions dealing with studies of specific episodes (case studies) will be welcome, provided they further increase physical understanding and are representative at least for the area where these events took place.
Particularly welcome will be contributions incorporating both numerical and conceptual modelling to improve our understanding of severe weather phenomena.
In general we will encourage the exchange of expertise and experiences related to the various topics connected to hazardous atmospheric phenomena and severe weather events. For this reason an interdisciplinary approach will be particularly welcome.
Potential topics for this session include i.a.:
• Flash-floods and heavy rain events;
• Freezing rain, icing and intense snow falls;
• Cold/heat events, even those occurring at small time scales;
• Tornadoes, waterspouts, derechos and downbursts;
• Severe wind storms;
• Intense Mediterranean cyclones;
• Tropical like cyclones;
• Polar lows, their evolution and impacts;
• Severe katabatic or foehn winds;
• Gap and orographic flows;
• Breaking of gravity waves, as well as severe turbulence;
The above-listed topics are of course not exclusive and the session’s Conveners eagerly anticipate papers on new ideas and approaches and novel understanding covering all aspects of atmospheric hazards and severe weather events.
