استخدام التحليل الطيفي لبناء نموذج رياضي للتنبؤ بالمعدلات الشهرية لدرجات الحرارة في مدينة الرمادي

Abstract EN

Temperature is considered as the most important climatic element that has a direct or indirect effect on other climatic elements.Variation of these elements results in a variation in temperature degrees and their impacts on various social and economic aspects This research aims at using the spectral analysis to findout a mathematical model of the time series for the monthly averages temperature degrees in Al- Ramadi city for the period 1984-2012.

The study has concluded that the studied time series has periodic effects through the (12) months whereby the proposed mathematical model based on one cyclical component.

This model can be used to predict the monthly averages of temperature in subsequent years.
