Analysis of interaction between the Eastern Mediterranean oscillation with variability of extreme temperatures in West of Iran

Extreme temperatures are climatical elements that in form of climate hazards affect over economic and social factors and knowledge and its forecasting for planning in the fields of agriculture, industry, and economy is essential. On other hand, its changes strongly linked with macroscale atmospheric-ocean fluctuations. According tothis issue, explanation of interaction of extreme temperatures and the Eastern Mediterranean pattern is main goals of this study. To identify the relationship between extreme temperatures and eastern mediterranean oscillation,the values of this index which are standardized have been studied and compared with normalized data using pearson correlation analysis,linear and polynomial process.The study results show that maximum temperature increases from 0.09 to 0.85o c and minimum temperature to 1o c with respect to average statistical periods in the negative phase.In contrast, in positive phases,maximum temperature from 0.1 to 0.4oc and minimum temperature decreases from 0.06 to 0.56o c with respect to average statistical periods. EMO effect on the extreme temperatures in spring season has been stronger than the winter. The highest monthly correlation between extreme temperatures and this pattern has been in March. Minimum temperatures with 300HP and maximum temperatures with 500 had highest correlation.
