Abstract: 

IN THIS RESEARCH, IN ORDER TO CONSIDER THE FREEZINGS WHICH OCCURRED IN EKBATAN (HAMEDAN) STATION, MINIMUM DAILY TEMPERATURES OF THIS STATION WERE STUDIED, THAT IN GENERALLY FREEZINGS WERE DIVIDED TO 3 LEVELS: WEAK-FREEZING, MIDDLE-FREEZING AND INTENSE-FREEZING.
THEN, WE DETERMINED THE RANGE OF TEMPORAL CHANGES AND THE ABUNDANCE OF THE FREEZING. ALSO WE HAVE TRIED TO INTRODUCE AN EMPIRICAL FORMULA WHICH CAN FORECAST THE DATE OF FIRST AUTUMNAL FREEZING ACCORDING TO THE DATE OF LAST SPRING FREEZING. BY CALCULATING DIFFERENT STATISTICAL PARAMETERS, PROBABILITY OF OCCURRENCE THE TEMPERATURE THRESHOLDS BETWEEN -15 TO 0 (OC) WERE DETERMINED FOR DIFFERENT MONTHS .IN ADDITION TO THIS, BY DIVIDING THE YEAR TO 36 DIFFERENT PERIODS OF TEN DAYS, WE HAVE TRIED TO CALCULATE TEMPERATURE OF DIFFERENT PROBABILITY PERCENTS.
