Abstract: 

THE EXACT CALCULATION OF REFERENCE EVARTANSPIRATION AND WATER REQUIREMENT IS IMPORTANT FOR THE BEST USE OF WATER SOURCE, CORRECT MANAGEMENT AND PERMANENT DEVELOPMENT. IN ORDER TO BE MORE PREPARED TO STRUGGLE AND REDUCE THE LOSS ACCOUNT, IT’S NECESSARY TO DO SOME RESEARCHES RELATED TO CLIMATE CHANGING, DUE TO THIS CHANGE. THE ENSO PHENOMENON IS ONE OF THE EFFECTIVE FACTORS IN CLIMATE CHANGE, THEREFORE THIS RESEARCH WILL DISCUSS THE THE EFFECTS OF ENSO PHENOMENON ON REFERENCE EVARTANSPIRATION, BY THE USE OF SOUTHERN OSCILLATION INDEX. FOR THIS REASON 9 CITIES AMONG THE COLD-DRY AND COLD-SEMI DRY CITIES WITH THE 50 YEAR OLD STATISTICAL PERIOD (1957-2006) WAS CHOSEN. THE RESULT OF USING THE CORRELATION TESTS IN SEASONAL SCALE, INDICATED THE POSITIVE RELATION OF SOUTHERN OSCILLATION WITH REFERENCE EVAPOTRANSPIRATION, IN UNDERSTUDY ZONES. ACCORDING TO OBTAINED RESULTS, QAZVIN IS THE MOST IMPRESSIBLE CITY AMONG THE UNDERSTUDY CITIES THE IMPRESSIBILITY OF REFERENCE EVAPOTRANSPIRATION IN FALL WAS CONTAINED ABOUT 75% OF IMPRESSIBILITY IN ALL SEASONS. GENERALLY THE UNDERSTUDY ZONES WITH 0.37CORRELATION COEFFICIENT ARE AFFECTED BY WESTERN FLUCTUATION INDEX, AS THE RATIO OF EVAPORATION AND EVARTANSPIRATION SOURCE OF EL NINO PHASE TO NORMAL PHASE IS DECREASED ABOUT 9.9 PERCENT, THE RATIO IN LA NINA PHASE TO NORMAL PHASE IS INCREASED ABOUT 8.3%. REFERENCE EVAPOTRANSPIRATION OF EL NINO PHASE DEALING WITH LA NINA PHASE, SHOWS A 10.85% DECREASE.
