Abstract

Weathers and climates are the main factors that affected the various activities of life. The increasing of human activity has made the change in environment biophysics components, which are major contributors about climate change. The most important of the climate change process are the emergence of extreme events, for example extreme rainfall events, that the rainfall have more than 50 mm intensity / day. To know characteristic of climate change occur, needed a model that represented the rainfall data in various meteorology station. Based on it, author make a modeling the extreme rainfall in Palu city using Java programming. The results of the extreme rainfall events that predictions in 10 years using software models and Java programming, in Palu city with using fourier series function order 5 with RSqure value 0,79, predicted the extreme rainfall will likely increase every year with the highest event are 2 times/years. The prediction was featuring the precise value with the real data. So, we can conclude that the extreme rainfall model tends to be accurate and can be used to predict the extreme rainfall in Palu city and in other cities .
