Rainfall frequency analysis in Indonesia using spatial approach

Abstract

This study discusses the frequency of rain anomalies per year which causes changes in the frequency of rain values and predictions of the difference between the frequency of rain that occurs and the frequency of rain that occurs higher using spatial approach. Based on climate factors (rainfall, water pressure and humidity) as the dependent factor in this study Using a significance level of 10% and the Spatial Error Model (SEM) method and the queen of the 1-point threshold close R2 is 63.6 %.
