Representations of max-stable processes based on single extreme events
extreme value statistics incremental representation max-stable process mixed moving maxima peaks-over-threshold weak convergence on function space
2012/11/23
This paper provides the basis for new methods of inference for max-stable processes \xi\ on general spaces that admit a certain incremental representation, which, in important cases, has a much simple...
MONITORING PHENOLOGICAL VARIABILITY ACROSS A TROPICAL SAVANNA ARIDITY GRADIENT WITH REMOTE SENSING ACROSS SEASONAL TO ANNUALAND EXTREME EVENTS
Savannas MODIS VI Tower fluxes
2014/5/6
Tropical savannas are key components of the global carbon and water cycles and understanding their functioning is critical to understanding ecosystem feedbacks to global climate. By observing broad sc...
Extreme events in total ozone over Arosa – Part 2: Fingerprints of atmospheric dynamics and chemistry and effects on mean values and long-term changes
Extreme events total ozone Arosa atmospheric dynamics and chemistry and effects mean values long-term changes
2010/11/3
In this study the frequency of days with extreme low (termed ELOs) and extreme high (termed EHOs) total ozone values and their influence on mean values and trends are analyzed for the world's longest ...
Extreme events in total ozone over Arosa – Part 1: Application of extreme value theory
Extreme events total ozone Arosa extreme value theory
2010/11/3
In this study ideas from extreme value theory are for the first time applied in the field of stratospheric ozone research, because statistical analysis showed that previously used concepts assuming a ...

Predictability of extreme events in a branching diffusion model
extreme events branching diffusion model
2010/4/6
We propose a framework for studying predictability of extreme events in complex systems. Major conceptual elements -- hierarchical structure, spatial dynamics, and external driving -- are combined in ...
Observing extreme events in incomplete state spaces with application to rainfall estimation from satellite images
extreme events incomplete state spaces rainfall estimation satellite images
2009/11/9
Reconstructing the dynamics of nonlinear systems from observations requires the complete knowledge of its state space. In most cases, this is either impossible or at best very difficult. Here, by usin...

2009/6/9
Changes in extreme weather events with climate change were estimated for northern Europe by
Rossby Centre coupled atmosphere – Baltic Sea regional climate model simulations. Two driving global climat...
A modeling approach to assess the hydrological response of small mediterranean catchments to the variability of soil characteristics in a context of extreme events
Digital Elevation Model soil characteristics pedotransfer function
2009/4/27
This paper presents a modeling study aiming at quantifying the possible impact of soil characteristics on the hydrological response of small ungauged catchments in a context of extreme events. The stu...
A stochastic model of throughfall for extreme events
canopy interception throughfall stochastic rainfall modelling rainfall intensity linear systems landslides
2009/3/3
Although it is well known that forest canopies reduce the amount and intensity of precipitation at the ground surface, little is known about how canopy interception modifies extreme events.
Probabilistic forecast of daily areal precipitation focusing on extreme events
Probabilistic forecast daily areal precipitation focusing extreme events
2009/12/30
A dynamical downscaling scheme is usually used to provide a short range flood forecasting system with high-resolved precipitation fields. Unfortunately, a single forecast of this scheme has a high unc...

2010/9/14
Since 2001, the villagers in Vanuaso Tikina, Gau Island, Fiji, have collaborated with the University of the South Pacific to manage their environmental resources to prepare them for difficult and chal...
Flood-risk mapping:contributions towards an enhanced assessment of extreme events and associated risks
Flood-risk mapping contributions enhanced assessment extreme events associated risks
2009/12/29
Currently, a shift from classical flood protection as engineering task towards integrated flood risk management concepts can be observed. In this context, a more consequent consideration of extreme ev...
