Abstract

West Seram District is an area of Maluku Province that has high rainfall intensity. Trend of erratic weather changes nowadays makes it important to know the information about rainfall intensity. To know this information, we need to know about rainfall period. This will give some contributions to forecast the rainfall later. Rainfall forecasting plays an important role in water resources management. It also can be used to control the unusual event related to rainfall. In this paper, we use Wavelet transform to analyze rainfall data of West Seram District of Maluku Province-Indonesia. The data that we use is data of monthly rainfall from 1991-2016 from Meteorology, Climatology, and Geophysics agency in AmbonMaluku-Indonesia. We also show some simulation results using Matlab.

基于小波变换的降雨预报(以印度尼西亚马鲁古省西西兰地区降雨期为例)
西瑟兰区是马鲁古省的一个降雨强度很高的地区。现今的天气变化趋势不稳定,因此了解降雨强度的资料十分重要。要知道这些信息,我们需要知道降雨周期。这对以后的降雨预报有一定的帮助。降雨预报在水资源管理中具有重要作用。它还可以用来控制与降雨有关的异常事件。本文利用小波变换对印尼马鲁古省西瑟兰地区的降水数据进行了分析。我们使用的数据是印度尼西亚ambonmaluku的气象、气候学和地球物理机构1991-2016年的月降雨量数据。并给出了一些Matlab仿真结果。
