Abstract AR
يهدف البحث إلى عمل دراسة دورية لبيانات الأشعة فق البنفسجية - ب لمحطات العريش و أسوان و الغردقة و جنوب الوادي في مصر.
تم تطبيق التحليل التوافقي لدراسة متسلسلات قيم الأشعة فوق البنفسجية - ب اليومية و الشهرية للمحطات الأربعة.
و قد وجد أن الموجات المسيطرة و التي ظهرت من تحليل البيانات اليومية للمحطات هي الموجات ذات الطول الموجي 13, و ,13.5 و 13.4, و 13.4 شهر على الترتيب.
و بتحليل قيم المتوسطات الشهرية للمحطات الأربع اتضح أن الموجة المسيطرة هي الموجة السنوية.
و تمت الاستفادة من هذه النتائج بالنسبة للموجات السنوية و استخدامها في التنبؤ بالأشعة فوق البنفسجية - ب للمحطات الأربع.
Abstract EN
Periodicity of the daily and mean monthly values of Ery-themal UV-B radiation of the stations El-Arish, Aswan, Hurghada and South Valley has been examined.
The harmonic analysis has been ap-plied to study the variations of the daily and monthly time series of Erythemal UV-B radiation of these four stations.
Results revealed that the dominant waves that appeared with the analysis of the daily time series of the four stations were 13, 13.
5, 13.
4, 13.4 months re-spectively.
The analysis of the mean monthly values for the four sta-tions showed that the dominant wave in these four time series was the annual wave with high statistically significant results.
These annual waves were used in forecasting UV-B radiation for these stations.
