Climate projections simulated by Global Climate Models (GCMs) are often used for assessing the impacts of climate change. However, the relatively coarse resolutions of GCM outputs often preclude their application to accurately assessing the effects of climate change on finer regional-scale phenomena. Downscaling of climate variables from coarser to finer regional scales using statistical method...

Instrument records from the past 200 years support a scientific consensus that climate is changing Trenberth et al. (2007). What is less clear is how to interpret these changes in an historical context spanning many hundreds, or thousands, or tens of thousands of years. The statistical question is this: how do we quantify and model historical climate without having direct observations beyond th...

The Dry Valleys are subdivided into three microclimate zones on the basis of summertime measurements of atmospheric temperature, soil moisture, relative humidity and wind-speed/ direction. Subtle variations in these climate parameters result in considerable differences in process geomorphology and in the development of unique landforms within each zone. The mapped zones include a coastal thaw z...

This paper describes a representation of the dynamics of human walking action for the purpose of person identification and classification by gait appearance. Our gait representation is based on simple features such as moments extracted from video silhouettes of human walking motion. We claim that our gait dynamics representation is rich enough for the task of recognition and classification. The...

Climate change studies involve changes in climate system of global long-term scales with effects on regional and local climates, down to shortrange time scales, like weather hazards and extremes. Climate studies significantly contribute to the future strategic planning in economic development and thereby must produce results with high level of confidence. Global climate models simulations of th...

We study a dynamic coordination process in which agents are uncertain about the actions of their fellow agents, and anticipate strategically relevant information. Because of the uncertainty and learning, (ir)reversibility of actions has important strategic consequences. We find that the reversibility option can either enhance or hamper efficient coordination, and we characterize the direction o...

El Niño – Southern Oscillation (ENSO) effects on the European circulation features and on the regional climate of Hungary are evaluated in this paper. European climate is represented by atmospheric macrocirculation patterns (MCPs). Local climate characteristics are linked to ENSO phases through regionally averaged temperature values and precipitation amounts. Significant statistical relationshi...
