Abstract

Climate Systems are complex, yet organized, systems that, in some years, exhibit definitive behavior and in others, random behavior. In the meantime, the subtropical high-pressure system, by shifting its location, creates occasional and sometimes random environmental events (Droughts or wetlands, etc. ) in one area. These environmental events are at different levels of balance, threshold and risk. In this article, in response to this issue, namely, identifying the behavior of tropical high-pressure systems from equilibrium to hazard, it was attempted to identify and evaluate this process in the form of systematic thinking. Since in the behavior of climatic systems, quantitative and qualitative studies interaction is essential. For this purpose, the research method in this study consists of two main parts: In the statistical research method, the data of 500 hPa pressure during the period 1948-2018 and the monthly precipitation data of 84 meteorological stations were analyzed and analyzed. Also, in the qualitative research method, the types of equilibrium, thresholds, hazards and environmental disasters in the behavior of high-pressure systems as well as its management type were studied. The results showed that in the warmest months of the study, the most significant impact on Iran has revealed several levels of equilibrium, in particular static, instantaneous, dynamic and transient equilibrium, which in some years face a threshold effect, which threatens to initiate risks. Is the environment (severe and very severe Droughts). Which will be subject to environmental disasters if disturbed and Drought-prone behavior is managed. Therefore, it can be said that combining quantitative and qualitative perspectives (in the form of active management) can be effective as a practical approach in the field of environmental management and predicting the behavior of systems to reduce risks.
