在分析任何地区的气候学时，最重要的特征之一是研究降水及其不同次谐波的周期性，以便研究观测资料的行为。本文计算了约旦地区降水的频率幅值、相位角和基本统计参数，以描述约旦地区降水的空间特征。根据约旦的气候区域选取了17个站点的降水记录。一、二次谐波分析能有效解释约旦地区90%以上的降水变化。为了描述该国的气候区域，计算了一次和二次谐波的振幅。最大振幅出现在北部山区。表示最大降雨时间的相位角也以等高线图的形式使用。研究发现，约旦以冬季为主要降雨季节，1月左右降雨量最大。变异系数显示了该国降雨的高变异性。
¶One of the most important features in analysing the climatology of any region is to study the precipitation and its periodicity of different harmonics in order to study the behavior of the observed data. In this study the amplitude of frequencies, phase angle and basic statistical parameters are calculated in order to depict spatial characteristics of precipitation over Jordan. Precipitation records of 17 stations were chosen according to climatic regions of Jordan. The first and second harmonic analyses explain more than 90% of the precipitation variation in Jordan effectively. The amplitudes of the first and second harmonic were calculated in order to describe the climatic regions in the country. The maximum amplitudes were found in the northern mountainous region. The phase angle representing the time of maximum rainfall is also used in the form of a contour chart. It is found that Jordan has its main rainfall season in winter with maximum around January. The coefficient of variation shows the high variability of rainfall of the country.
