Climate variables on a scale of time and space are certain complexities that causes oscillation behavior in this variables. Recognition these fluctuations (convert and overt behavior) in environmental planning, the hydrological cycle, human activities and the effects of fluctuations in the risk zoning and creating crisis necessity of their study. Therefore, to understand the fluctuations of trend modeling technique, and extracting unseen cycle with spectral analysis tool precipitation series and mean temperature of Anzali Bandar synoptic station, in order to understand the trend and its type, unseen behavior and extracting of cycles for 64-year (1951-2014) was evaluated in three levels of confidence. The results of this study with modeling trends by the family of polynomial, the existence linear trend in precipitation(decreasing) and the share of trend for temperature (increasing) shows. Also, extraction of cycle showed cycles with 3 and 5 years return period is the most abundant element in both climates were examined.
