Relation Of ENSO And Climate Change And Its Effects OnFluctuation Of Temperature In The Khorasan Province

The long-term forecasting and monitoring of Climatological parameters depends onidentification of all effective factors that are affects on this phenomenon. One of theseparameters in the weather signal. These signals are the determinable and specificpattern and occur in the distinguished regions in the world, but its effects areworldwide. One of the famous signals is ENSO phenomenon, which have two phases.In this paper with using annual and seasonal correlations between SouthernOscillation Index (SOI) and temperature data, the effective amounts of ENSO phaseson the differences of these factors was studied in the all regions of Khorasan provincein I.R.of Iran, then for more comprehensive study the classification maps in relation ofENSO and variability of temperature were drown. It was concluded that the mentionedparameter in the whole of the province especially in central and north strip have shownsignificant action to ENSO,in other word the average of temperature correlationindices are negative annually and seasonally ,it means when SOI amounts areincreased the temperature in Khorasan province will be decreased. With regard toincreasing the above weather parameters in all regions of Khorasan province at thetime of ENSO's negative phases (El Nino condition) variation of temperature could berelated to the changes of pattern of occurrences this phenomenon (ENSO) due toclimatic change around the world.
