Modeling climate change effects on winter ski tourism in Andorra
Climate Research, 2012Co-Authors: Marc Pons-pons, B Sureda, Martí Rosas-casals, Peter A Johnson, Eric JoverAbstract:Mountain regions have been identified as especially vulnerable areas to climate change. Changes in snowfall, glacier retreat and shifts in biodiversity amount and distribution are some examples of the sensitivity of mountain ecosystems. Moreover, in many mountain economies, reliable snow cover plays a key role as an important resource for the winter tourism industry, the main income source and driving force of local development in such regions. This study presents a georeferenced agent-based model to analyze the climate change impacts on the ski industry in Andorra and the effect of snowmaking as future Adaptation Strategy. The present study is the first attempt to analyze the ski industry in the Pyrenees region and will contribute to a better understanding of the vulnerability of Andorran ski resorts and the suitability of snowmaking as potential Adaptation Strategy to climate change. This study projects a reduction on the ski season length and the drop of the number of skiers especially in the lowest elevation ski resort of this region. Moreover, this work indicates that snowmaking cannot completely solve the problem of ensuring snow cover at low elevation ski resorts and should be considered as a suitable short-term Strategy, but not as a sustainable long-term Adaptation Strategy. The resulting model can be used as a planning support tool to help local stakeholders understand the vulnerability and potential impacts of climate change and in the decision-making process of designing and developing appropriate sustainable Adaptation strategies to future climate variability

The impact of climate change on ski season length and snowmaking requirements in Tyrol, Austria
Climate Research, 2010Co-Authors: Robert SteigerAbstract:In this paper, the development and validation of a ski season simulation model (SkiSim 2.0) is described and results of the climate change assessment for 3 ski areas in Tyrol, Austria, are presented. The results of the validation process suggest that SkiSim 2.0 is an appropriate tool to simulate ski season lengths and snowmaking requirements at different altitudes and in different climatic subregions of the study area. Climate change impacts on ski season length are considerably less when incorporating snowmaking. All 3 modelled ski areas remain snow reliable until the 2040s (A1B) to the 2050s (B1). By then, current snowmaking technology has reached its technological limits. The required snow volume until the end of the century is projected to increase by up to 330%. Although snowmaking is a suitable Adaptation Strategy for the next decades, it is unlikely to be a sustainable Adaptation Strategy beyond the middle of the century. Besides altitude, local climate characteristics clearly influence ski season length, requiring the use of localized climate data. A com- prehensive study of the research area, modelling all ski areas, is needed to assess the vulnerability of the ski marketplace in Tyrol.

SNOWMAKING - A SUITABLE Adaptation Strategy? EXAMPLES FROM TYROL / AUSTRIA
2007Co-Authors: Robert SteigerAbstract:Ski tourism is among those sectors of tourism that are affected the most by climate change. Snowmaking represents in the view of ski area managers the only possible Adaptation Strategy to rising temperatures, although it is dependent on cool temperatures. Previous studies about climate impact on ski tourism in Austria only focused on natural snow conditions. The present situation with snowmaking capacities covering 50 % of the skiing terrain in Austria and about 75 % in Tyrol (in the year 2007) raises the question if snowmaking can be a suitable Adaptation Strategy for low elevated ski areas in Tyrol. In this study climate data and lift operation data were analyzed to visualize the correlation between climate and season length. A snowmaking model was integrated to assess the technologys potential for today and a +2°C climate scenario. The results demonstrate that snowmaking can provide desired season lengths today, but also that - even with an intensification of snowmaking - it cannot solve the problem of shortening ski seasons at lower elevations in the future.

stride period Adaptation of a biomimetic running hexapod
The International Journal of Robotics Research, 2004Co-Authors: Jorge G Cham, Jonatha K Karpick, Mark R CutkoskyAbstract:We demonstrate an Adaptation Strategy for adjusting the stride period in a hexapedal running robot. The robot is inspired by discoveries about the self-stabilizing properties of insects and uses a sprawled posture, a bouncing alternating-tripod gait, and passive compliance and damping in the limbs to achieve fast (over four body-lengths per second), stable locomotion. The robot is controlled by an open-loop motor pattern that activates the legs at fixed intervals. For maximum speed and efficiency, the stride period of the pattern should be adjusted to match changes in terrain (e.g., slopes) or loading conditions (e.g., carrying an object). An ideal Adaptation Strategy will complement the design philosophy behind the robot and take advantage of the self-stabilizing role of the mechanical system. In this paper we describe an Adaptation scheme based on measurements of ground contact timing obtained from binary sensors on the robot’s feet. Wediscuss the motivation for the approach, putting it in the context o...

stride period Adaptation for a biomimetic running hexapod
Proc. of ISRR2001, 2003Co-Authors: Jonatha K Karpick, Jonatha E Clark, Jorge G Cham, Mark R CutkoskyAbstract:We demonstrate an Adaptation Strategy for adjusting the stride period in a hexapedal running robot. The robot is inspired by discoveries about the self-stabilizing properties of insects and uses a sprawled posture, a bouncing alternating-tripod gait, and passive compliance and damping in the limbs to achieve fast, stable locomotion. The robot is controlled by an open-loop clock cycle that activates the legs at fixed intervals. For maximum speed and efficiency, this imposed stride period should be adjusted to match changes in terrain or loading conditions. An ideal Adaptation Strategy will complement the design philosophy behind the robot and take advantage of the self-stabilizing role of the mechanical system. In this paper we describe an Adaptation scheme based on measurements of ground contact timing obtained from binary sensors on the robot’s feet. We discuss the motivation for the approach, putting it in the context of previous research on the dynamic properties of running machines and bouncing multi-legged animals, and show results of experiments.
