Abstract
In geopolitics literature, small and low-endowment states that compound lesser geopolitical potentiality and weight are considered as the trivial scale agents in comparison with the first and second level powers. These agents, in spite of the local geopolitical codes but sometimes can effect on the regional and even global events of geopolitics. The Caucasian region, historically, have had a field for appearance and exposition of sub-khans that their overall actions and agencies effected the events of the region and due to its cultural proximities to Iran, have effected in Iran’s geopolitical functions in national scale. The present paper with descriptive-analytical method, have studied historical role of the local agencies in geopolitical events of the Caucasia and their impression on the great scale events. Secondly, the paper has studied the quality of the chosen countries of the region in current circumstances of the global system. Results indicate that the Caucasian countries act according to their historical legacy as a small-scale agents among the great scale actors.

Abstract
Qarabagh region and consequently Zangzor Corridor is of special importance for Iran due to its geopolitical and geoeconomic capabilities. This practical article is devoted to the explanation of the future scenarios for Iran caused by the Zangzor Corridor. The methodology governing the research is descriptive and analytical. The required data has been collected by library and field methods and analyzed using Micmac and Scenario Wizard software. The results of the research showed six variables: Israel's presence in the Karabakh region, the location of the Karabakh region in the orbit of the US and the West, Iran's gas export, especially to Turkey, Iran's territorial integrity (especially the Turkic provinces), Iran's transit role in international transportation, and Iran's geopolitical position. They were chosen as the key influencing variables of Zangzor Corridor on Iran. In this regard; The possible situations related to six scenarios with strong compatibility showed: the situations that describe the scenarios facing Iran as critical due to the impact of the Zangzor Corridor, include the most possible possible situations. On this basis, the scenario of geopolitical collapse was formulated and it was concluded that the future of Iran's security in the Caucasus depends on its ability to create an effective strategy for managing challenges and exploiting opportunities. Only by strengthening regional cooperation and adopting prudent policies, Iran can take steps to protect its national interests and ensure stable security in this region

Abstract
In order to detect climate change, a variety of climate indicators can be used which is often considered temperature and precipitation. In order to investigate the effect of climate change on the amount of precipitation in the north coast of the Persian Gulf, it simulated the precipitable water for 2017-2050 based on the RCP4.5 model of the Hadcm3 model. The NCEP / NCAR base-station data with an arc-value of 0.125 was used to analyze the past and present precipitable water patterns and to reveal the process of this time series. Time series analysis of precipitable water was performed using two SENS tilt estimators and Man-Kendall test. The results indicated that the annual time series of rain water was increasing in the region, every year, 0.05 mm, the precipitated water increased and it tended to become more homogeneous, this increase in the significance level of 0.95. The precipitation rate in the eastern part of the region was higher than other areas. Before 1989, several fluctuations were observed in the rainy season of precipitable water, but none was statistically significant at the confidence level of 95%, but since 1989, the trend has increased significantly at a confidence level of 0.95. This spatial behavior of precipitable water can actually have occurred in response to the increase in the overall temperature of the area and can be considered as a profile of climate change in the region.
