Future climate resources for tourism in Europe based on the daily Tourism Climatic Index

Climate is an important resource for many types of tourism One of several metrics for the suitability of climate for sightseeing is Mieczkowski's "Tourism Climatic Index" (TCI), which summarizes and combines seven climate variables By means of the TCI, we analyse the present climate resources for tourism in Europe and projected changes under future climate change We use daily data from five regional climate models and compare the reference period 1961-1990 to the A2 scenario in 2071-2100 A comparison of the TCI based on reanalysis data and model simulations for the reference period shows that current regional climate models capture the important climatic patterns Currently, climate resources are best in Southern Europe and deteriorate with increasing latitude and altitude With climate change the latitudinal band of favourable climate is projected to shift northward improving climate resources in Northern and Central Europe in most seasons Southern Europe's suitability for sightseeing tourism drops strikingly in the summer holiday months but is partially compensated by considerable improvements between October and April
