Guest blog by Milan Gazdic , University of Belgrade (Serbia) In Montenegro, forests and forest land occupy approximately 70% of the territory of the country. Montenegro forests provide many benefits and services to society, including clean water and air, recreation, wildlife habitat, carbon storage, climate regulation, and a variety of forest products. Climate influences the … Continue reading Potential effects of climate change on fires in the Balkan area

Guest blog by Natacha Le Grix and Elisabeth Tschumi, Universität Bern, Switzerland What could possibly bring together experts of the copula theory, hydraulic engineers and climate scientists working on extremes like floods and wildfires? Well, the first DAMOCLES Training School on Statistical Modelling of Compound Events. From 23.9-4.10.2019, a group of 23 PhD students and Post-docs … Continue reading First DAMOCLES training school
Guest blog by Alexandre Ramos, Instituto Dom Luiz, Portugal An Atmospheric River (AR) is a long, narrow, and transient corridor of strong horizontal water vapour transport that is typically associated with a low-level jet stream ahead of the cold front of an extratropical cyclone. The water vapour in ARs is supplied by tropical and/or extratropical moisture … Continue reading Atmospheric Rivers from a Compound Event Perspective
Lead Organizers: Colin Raymond, Radley Horton Steering Committee: Amir AghaKouchak, Olivia Martius, Thomas Wahl, Jakob Zscheischler, Suzana Camargo, Alex Ruane, Adam Sobel, Michael Oppenheimer, Noah Diffenbaugh, Sonia Seneviratne This workshop took place at Columbia University (New York, USA) on May 28-31. It was designed to bring together the communities of researchers studying extreme events connected … Continue reading Summary: Workshop on Correlated Extreme Events
Guest blog by Edoardo Vignotto, University of Geneva, Switzerland Statistical modelling of extreme climatological events has recently gained a lot of interest. These events may occur in many different situations, often with dramatic consequences. Some examples are flooding, heat waves, extreme wind speeds, spatially concurring rainfall and long drought periods. In all these cases, it … Continue reading Meteorological and agricultural hazards in high drought risk scenarios
Guest blog by Benjamin Poschlod Southern Norway is regularly exposed to floods triggered by heavy precipitation and snow-melt. A combination of high temperature leading to snow-melt and heavy rainfall is an example of a compound event, which leads to severe flooding when run-off due to snow-melt adds to river discharge from the rainfall. These compound … Continue reading The compound event of heavy rainfall combined with snow-melt in southern Norway
Guest blog by Cenk Sezen Rain-on-snow events Rain-on-snow (ROS) floods, that is, the combined occurrence of snowmelt and rainfall events can cause huge economic impacts and endanger human lives due to a significant increase in the magnitude of runoff compared to only snowmelt or only rainfall events. Forecasting of ROS floods is difficult because of … Continue reading Investigating climate change impact on Rain-On-Snow events
Many extreme impacts on society are caused by compound events, which were recently defined as a combination of multiple drivers and/or hazards contributing to societal or environmental risk. Compound events include, for example, concurring precipitations and storm surges causing flooding along low-lying coastal areas; heatwaves enhanced by drought conditions; strong wind episodes combined with drought … Continue reading Towards a categorisation of statistical methods to study compound events
Chairperson: Bart van den Hurk Conveners: Nina Nadine Ridder | Co-conveners: Bart van den Hurk, Philip Ward, Seth Westra, Jakob Zscheischler, Samuel Jonson Sutanto, Claudia Vitolo, Henny A.J. Van Lanen This is a short summary of the oral session at the EGU 2019 where once again this year a session on understanding and modelling compound … Continue reading Session report: Understanding and modelling compound climate and weather events and their impacts
Guest blog by Davide Faranda, M. Carmen Alvarez Castro Mediterranean cyclones or "medicanes" Windstorms, extreme precipitations and instant floods seems to strike the Mediterranean area with increasing frequency. These events occur simultaneously (compound extreme events) during powerful tropical-like Mediterranean cyclones, also called medicanes. Medicanes are mesoscale cyclones with a diameter usually smaller than 300 km, … Continue reading Medicanes: tropical-like-cyclones in the Mediterranean Sea and their uncertain fate with climate change
