Abstract: الملخص يهتم هذا البحث بتحليل السجلات المطرية لمعدلات الهطول السنوي للأمطار لمحطات الأرصاد الجوية لعمان وإربد والمفرق. استخدمت عدة طرق رياضية إحصائية(Normal statistical, Harmonic and Power Spectrum and Time Series) لتحليل المعدلات السنوية للأمطار. أظهرت النتائج أن أكثر دورية محتملة هي 3-4 سنوات في كافة المحطات، أما تحليل السلاسل الزمنية فأظهرت النتائج أنها مقاربة للقياسات الفعلية، وعليه يمكن استخدامه من قبل الدارسين أو متخذي القرار للتنبؤ بالقراءات المستقبلية. Abstract This article deals with the statistical analysis of the rainfall measurements for three meteorological stations in Jordan, Amman Airport (central Jordan), Irbid (northern Jordan) and Mafraq (eastern Jordan). Normal statistical, harmonic and power spectrum analysis as well as time series analysis were performed on the long-term annual rainfall measurements at the three stations. The result showed that the most expected cyclicity is in the order of 3-4 years in all the meteorological stations. A time series model for each station was adjusted, processed, diagnostically checked and lastly an ARIMA model for each station is established with a 95 pre. confidence interval. The results indicate a decreasing trend for forecasted rainfall results in all station.
