Abstract

In this research, effect of NORTH ATLANTIC OSCILLATION and sea surface TEMPERATURE (SST) of Atlantic Ocean on PRECIPITATION and TEMPERATURE of LORESTAN PROVINCE and its effect on occurrence of drought and wet in this province were investigated. So, data of TELECONNECTION indices used as an index for determination of fluctuations of pressure and sea surface TEMPERATURE in Atlantic Ocean, amount of PRECIPITATION and TEMPERATURE of synoptic stations in LORESTAN PROVINCE (Koramabad, Aligudarz & Boroujerd) used in long term statistic period. The main method in this research is Pearson CORRELATION and MULTIPLE REGRESSION analysis. Result shows that NAO index has more CORRELATION with TEMPERATURE and PRECIPITATION of stations in cold months. Positive phase of NAO index is related by droughts of Aligudarz station and wet years of Boroujerd station. CORRELATION matrix of SST patterns shows that most of these patterns have weak & direct CORRELATION with PRECIPITATION and TEMPERATURE variability of LORESTAN PROVINCE. MULTIPLE REGRESSION equation shows that TELECONNECTION patterns reveal 53, 57 & 70 percent of PRECIPITATION variability of Koramabad, Aligudarz & Boroujerd and 66, 45 & 58 percent of TEMPERATURE variability in these stations consequently. Equations and outputs of Backward method shows that among other patterns, TSA pattern is the most effective pattern in presentation of variability of PRECIPITATION and TEMPERATURE of stations. So, AMM, NTA & TNA patterns has the most roles in this variability.
