In this study have been paid on analysing Thunderstoms in a period of 25 years in Shiraz (1984-2008). Therefore, data on sea level pressure, geopotential height levels 850 and 500 hpa in the rainfall day of NCEP/NCAR databse prepared and extraction levels above the map drawing software environment GRADS Were drawn. The extreme rainfall patterns Related to Shiraz have been identified and analyzed. By examining maps of sea level pressure, 850 and 500 hpa, three general patterns were identified for Shiraz thunderstorm rainfall. In the first pattern (1 March 1998), the low-pressure lingual of the Sudan country, large parts of the study area is located. The system In addition provides moisture, instability in the level do too. And in the level of 850 and 500 hpa, area studied the influence of anticyclonic centers are located in the western and ridges. In second type of the pattern (December 6,2003) at sea level, the area studied is affected by center anticyclone, and the level of 850 and 500hpa area at the front of the trpugh with a curved contour 1450 and 5720 geopotential meters located and the conditions are very unstable at this level. And the third pattern (26 March 2003) Low-pressure center with a central pressure of 1004hpa is located on the country. At this level, the currents are such that relatively moist air flows from the Caspian to the North West and the West. The levels of 850 and 500hpa area studied are located under the trough axis above and instability intensifies levels above.

Human beings have spent many decades trying to confront and overcome the nature. This is a continuous confrontation and fight against the nature whose unbounded forces enlarge and result in more catastrophes every day. Recently, this endeavor and fighting have appeared much more useful, due to the scientific development and related communication and information strategies in crisis management.
In competitive environment, survival depends on not being taken by surprise and success is the reward of taking someone by surprise. Therefore, the necessity of being prepared and having a coherent plan to fight natural forces in the context of crisis management is obvious. The present study tries to define crisis along with its different forms and investigate factors which result in the importance of these phenomenon in human societies. Moreover, it introduces concepts of crisis management and its different phases while defining Telegeoinformatics sciences. Finally, a Telegeoinformatic structure was proposed to launch crisis management system

The study of world records suggests that the application of GIS in planning tourism management started for the first time in the early 1990's, but the development of the application of GIS in this field has not been as rapid as its development in other areas. Obviously, this ability offers plenty of help for planners and tourists to do their own planning. The planners use this ability to identify possible deficiencies and weaknesses, as well as the trend of changes to plan for improving conditions and the development of tourism activities. The purpose of this study is to investigate and describe the functions of geographic information systems in the emerging tourism industry in the country. This research is descriptive-analytical and technical. The results of this study indicate that GIS can be used to estimate different information needs, estimate the indicator, and generally help planners and tourists, as well as to monitor and evaluate tourism activities.

Today, the goal of tourism planning is to fulfil the need to create sustainable planning in order to prevent the destructive effects of tourist activities on the tourist environments and areas (cities, villages, etc.), and that although tourist activities have achieved better goals and economic effects, these goals should be used to satisfy the tourists and to improve the quality of the welfare and life of local communities (residents) and human beings. The Rijab area is located in the Zagros Mountain range as a geotourist area. With its typical geomorphologic features and the presence of tourist attractions, this region has high tourist potentials. This article aims to study the capabilities and limitations of geotourism and to develop the best strategy for the prosperity and improvement of tourism management in this region. The research method is a combination of two methods of secondary and field studies. In the secondary method, in addition to the subject-related texts, some of the information needed, especially quantitative information, was gathered through referrals to libraries, departments and organizations. In field study, information was gathered through direct observation (image and video), interviews and questionnaires. Ten Delphi questionnaires were completed and then analyzed by SWOT model. Finally, internal and external factors were evaluated and the strategies of these factors were extracted. The extraction of internal and external matrices showed that WO strategies have a higher priority for implementation, and ultimately these factors, by quantitative Strategic Planning Matrix (QSPM), were prioritized as follows: 1- Strengthening the specialist force; 2. Construction and improvement of the status of residential-service units; 3. Protection of typical tourism attractions (especially geomorphologic); 4. vast advertisements; 5. Familiarizing local people with the culture of tourism; 6. Adding to the extent of the tourist area by utilizing the surrounding lands and the participation of investors and government.
