Analysis of Summer Tourism Period for Austria Based on Climate Variables on Daily Basis
2007
An analysis of the meteorological and climatological parameters relevant for tourism climatology and human biometeorology is based on climate conditions for 1961 - 1990 and scenarios for the period 2021 - 2050, calculated by the Max-Planck-Institute for Meteorology in Hamburg. For Austria it can be expected that in the future (2021-2050) the summer tourism period will start earlier and end later in the year compared to the current situation. The period for recreation and leisure will be extended; also the months in spring and fall will offer comfortable thermal conditions for outdoor activities. However, this positive trend is opposed by not only an increase of the frequency and intensity of heat stress but also by an increase in days with sultriness in areas below 1000 m above sea level. It is also likely that there will be a slight increase of days with longer rain events. An decrease of the number of days with light or no rain will not compensate for that.

The climate tourism potential of a region can be described by methods used in human biometeorology and applied climatology. Frequency analyses based on complex thermal bioclimatic indices (e.g. physiologically equivalent temperature) and diagrams of precipitation patterns based on thresholds offer new approaches of visualisation. An integral approach for tourism climatologic analyses is provided by the climate-tourism/transfer-information-scheme that also bases on frequency distributions of relevant factors and parameters which are important for a destination. The knowledge about the vertical variability of tourism climatologic factors is of high importance because of the several kinds of tourism activities affected by weather. The same holds for a quantification of extreme events like heat waves because of their possible effects on health and recreation over a year's course. The results show that the vertical gradient of bioclimatic and tourism-related parameters can be of value when developing strategies of adaption to climate change.
Climate Change Impact Assessment of Ski Tourism in Tyrol.
2013
Climate change poses a serious threat to the highly snow-dependent ski tourism industry. In this paper the potential impacts of climate change on ski areas in Tyrol (Austria, Italy) are investigated. A ski season and snowmaking simulation model ‘SkiSim2’ was applied to 111 ski areas. Model results suggest that all ski areas could ensure a 100-days season until the 2030s to the 2040s (high/low emission scenario) assuming a 100% snowmaking coverage and state-of-the-art snowmaking system. The Christmas holidays are a particularly sensitive season period, where already in the 2020s some ski areas do not fulfil economic thresholds. A warming greater than 3?C would force most ski areas to close their business not considering developments in snowmaking technology and economic thresholds of snowmaking costs. Regarding the snow demand to ensure a 100-days season independent of any technological limits, snow production would have to be multiplied by up to a factor of 4. It is questionable whether all ski areas will be able to afford the increasing snowmaking costs and therefore the most vulnerable regions should rethink their touristic positioning.
Summer tourism in Austria and climate change
MODSIM 2007 International Congress on Modelling and Simulation (Oxley, L. and D. Kulasiri, Eds.) Modelling and Simulation Society of Australia and New Zealand, 1939
According to the 4th assessment report 4AR of IPCC the increase of global air temperature in 21st Century will be strongest over the continents in higher northern latitudes and an increase of extremely hot temperatures and heat waves is very likely (probability> 90%). Austria-situated between 46 and 49 northern latitude-and its economy are strongly affected by climate change and its consequences. Two thirds of the GDP comes from the service sector, where Austria profits particularly from tourism. The effect of climate change on ...

Outdoor tourism and recreational activities strongly depend on actual meteorological conditions. Traditionally, in three studied regions, the peak of tourists' streams concentrates in summer months. In the present study, we assess suitability of weather conditions for various forms of outdoor tourism in different regions of Serbia, Poland and Ukraine. Additionally, how the location of the station differentiates temporal patterns of weather suitability will be discussed. To analyse the suitability of weather conditions for various forms of outdoor recreation, we have chosen 23 meteorological stations of the national weather networks which represent different tourism areas and destinations. For each weather station, daily data for the period 2000-2017 of air temperature, relative humidity, total cloud cover and wind speed (at 10 m above ground) for 12 UTC as well as the daily maximum and minimum temperature, precipitation totals and snow cover depth were applied. Suitability of climate for outdoor recreation and tourism is assessed by the Weather Suitability Index (WSI) based on Błażejczyk's bio-thermal weather classification. The results of research show that passive forms of recreation (sun and air bathing) are preferred mostly in months from May till August or September. For the active forms of recreation, weather in summer months is very oppressive, especially in the resorts located in the south (Serbia, southern Ukraine). Active forms of recreation are preferred there in autumn, winter and spring months.
Modeling climate change effects on winter ski tourism in Andorra
Climate Research, 2012
Mountain regions have been identi fied 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.

Possible climate change will modify snowcover depth and change the characteristics of winter tourism and skiing districts. Our model describes seasonal snow-cover depth related to altitude in six Alpine climate regions as the best ®t of all snow stations. Data cover 30 winter seasons (November to April values) from 1965 to 1995. We modi®ed the data according to a scenario of temperature and precipitation change (2°C warming, no precipitation change) and achieve a new simulated snow-cover depth. The indicators MARP (mean altitude of resident population) and MASPSL (mean altitude of starting point of ski lifts) serve as references for``critical altitudes'' of Austrian districts. A warming implies a reduction of snow in all districts, but the loss is overproportional in lower altitudes. The direction of economic impacts is clear ± income losses and adaptation costs ± but magnitude and time frames remain uncertain.

An analysis of climate simulations from a point of view of tourism climatology based on two regional climate models, namely REMO and CLM, was performed for a regional domain in the southwest of Germany, the Black Forest region, for two time frames, 1971-2000 that represents the twentieth century climate and 2021-2050 that represents the future climate. In that context, the Intergovernmental Panel on Climate Change (IPCC) scenarios A1B and B1 are used. The analysis focuses on human-biometeorological and applied climatologic issues, especially for tourism purposesthat means parameters belonging to thermal (physiologically equivalent temperature, PET), physical (precipitation, snow, wind), and aesthetic (fog, cloud cover) facets of climate in tourism. In general, both models reveal similar trends, but differ in their extent. The trend of thermal comfort is contradicting: it tends to decrease in REMO, while it shows a slight increase in CLM. Moreover, REMO reveals a wider range of future climate trends than CLM, especially for sunshine, dry days, and heat stress. Both models are driven by the same global coupled atmosphere-ocean model ECHAM5/MPI-OM. Because both models are not able to resolve meso-and micro-scale processes such as cloud microphysics, differences between model results and discrepancies in the development of even those parameters (e.g., cloud formation and cover) are due to different model parameterization and formulation. Climatic changes expected by 2050 are small compared to 2100, but may have major impacts on tourism as for example, snow cover and its duration are highly vulnerable to a warmer climate directly affecting tourism in winter. Beyond indirect impacts are of high relevance as they influence tourism as well. Thus, changes in climate, natural environment, demography, tourists' demands, among other things affect economy in general. The analysis of the CLM results and its comparison with the REMO results complete the analysis performed within the project Climate Trends and Sustainable Development of Tourism in Coastal and Low Mountain Range Regions (CAST) funded by the German Federal Ministry of Education and Research (BMBF).
