Abstract—Tourism is a phenomenon respected by the human communities since a long time ago. It has been evoloving continually based on a variety of social and economic needs and with respect to increasingly development of communication and considerable increase of tourist’s number and resulted exchange income has attained much out come such as employment for the communities. For the purpose of tourism development in this zone suitable times and locations need to be specified in the zone for the tourist’s attendance. One of the most important needs of the tourists is the knowledge of climate conditions and suitable times for sightseeing. In this survey, the climate trend condition has been identified for attending the tourists in Isfahan province using the modified tourism climate index (TCI) as well as SPSS, GIS, excel, surfer softwares. This index evoluates systematically the climate conditions for tourism affairs and activities using the monthly maximum mean parameters of daily temperature, daily mean temperature, minimum relative humidity, daily mean relative humidity, precipitation (mm), total sunny hours, wind speed and dust. The results obtaind using kendal’s correlation test show that the months January, February, March, April, May, June, July, August, September, October, November and December are significant and have an increasing trend that indicates the best condition for attending the tourists. S, P, T mean , T max and dust are estimated from 1976-2005 and do kendal’s correlation test again to see which parameter has been effective. Based on the test, we also observed on the effective parameters that the rate of dust in February, March, April, May, June, July, August, October and November is decreasing and precipitation in September and January is increasing and also the radiation rate in May and August is increasing that indicate a better condition of convenience. Maximum temperature in June is also decreasing. Isfahan province has two spring and fall peaks and the best places for tourism are in the north and western areas. Keywords—Climate, Tourism, Correlation Test, Tourism Climate Index, Isfahan Province I. INTRODUCTION OWADAYS, tourism industry is beyond an industry and as a world s dynamic and social phenomenon has own special complications. A phenomenon with an integrated and hidden mechanism takes a variety of forms at different times and places and consequently leaves different impacts on the human communities. Amelong and Winer [1] studied the worlds future climate change, Mediterranean zone and the possibility of over warming the Mediterranean sea in the summer and suggested that the north of Europe is more suitable in this season form the view of the weather and also some typical parts of Mediterranean sea are appropriate and pleasant in spring and fall so that these local and time changes in tourism attraction are important factors in spatial distribution of the tourism development. Hin and colleagues [2] have studied the condition of tourism convenience in Spain using TCI method and case studes on this country. A.

Khorasanizadeh, Najafabad Branch, Islamic Azad University, (e-mail: Farnooshkh1365@gmail.com) They have forecasted that condition will have the least difference by 2060 and referred to the summer form the view of the tourism favorable convenience. It may referred to PRECH-NIELSON 2008 about climate changes and tourism using TCI index in Europe as well as CISCAR book which studies the Europe climate convenience in the present and future using TCI index regarding the climate changes. A recent development was to extend the model to include domestic tourism, expenditures on tourism and the length of stay [3]. It is this version of the model that will be discussed here. Subsequent developments of the model have focussed on examining the effects of various climate policies on the flows of tourists [4]. Scott and McBoyle [5] apply the tourism index approach to the impact of climate change on city tourism in several North American cities. Cities are ranked according to their climatic appropriateness for tourism and the relationship between tourist accommodation expenditures is examined. Then this ranking is recalculated using data fromscenarios of (the lower and middle bounds of) climate change for the 2050s and the 2080s. Climate change has the potential to alter weather conditions and landscapes at tourist destinations, and is therefore likely to modify tourist demand and travel patterns [6]. They may alter the ecological systems of an area, which may in turn alter the quality of the recreation experience [7]. Gössling and Peeters [8] conclude that in an average holiday or short break involving air travel, 60–95% of its contribution to global warming will be caused by the flight. The growth, and predicted future growth, in international tourism is a major concern. International tourist arrivals grew to 903 million in 2007 and are forecast to increase to 1.6 billion in 2020 [9]. International tourism is largely dominated by developed countries. The current tourism trend in these industrialised countries has been described as hyper-mobility [10] and is characterised by the taking of several short-breaks and longer holidays every year. Estimates suggest that carbon dioxide emissions from air travel could rise to more than 15% of total carbon dioxide emissions from all sources by 2050 [11]. Several studies report low awareness of the impact of air travel on climate change [12]. In the UK a number of quantitative studies have examined public attitudes towards air travel [13]. In the most recent [14] study, 66% of total respondents said they believed that air travel harms the environment, with 44% of these respondents specifically mentioning climate change and 64% saying they would be willing to pay more for air travel in order to reflect the environmental harm. In a quantitative study, that asked directly about climate change, 62% would take fewer flights to reduce impacts [15]. Outside tourism, there are issues generally with climate change action and people have little faith their actions will make a difference, most individuals finding it difficult to disentangle themselves from high carbon lifestyles [16]. This could be because people feel they have earned the right to fly and take holidays [17]. A.Gandomkar, F.
