Effect on planetary climate modeling precipitation indices in East Azarbaijan
Case study: city of Tabriz
Abstract
In order to model and assess the direct and indirect effects of climate indices on monthly and annual precipitation in East Azarbaijan, the Station of Tabriz because of having a long-term statistics as well as the representative of the province was investigated .therefore, the amounts of precipitation, relative humidity and maximum temperature of the city and 13 planetary climatic indicators in the annual and monthly time intervals through Using path analysis and structural equation statistical methods were evaluated and explored.The Results showed that the modeling of annual rainfall in the months of February, March, May, September and October based on the conditions of the model are 95% significant where as it wasnât so far the months. Thus the October model with 61.8% of variance precipitation is as the best model of the year involving the seven variables as well as North Atlantic Oscillation Index(NAOI) compared to the other indicators.The evaluation of Meaningful assessment models show that the quality, type and amount of precipitation in the form of direct and indirect effects are different in different months. Generally, according to the indices of climate models it can be expressed that the indices of climate can be the representative of the centers and they are effective both directly and indirectly in terms of precipitation of Tabriz.
