| Abstraksi | : | Indonesian region often experiences hydrometeorological disasters such as floods and landslides. To mitigate the losses from such disasters, an early warning system is needed. PSTA LAPAN is developing an early warning system called SADEWA (Satellite-based Disaster Early Warning System). The performance of this early warning system needs to be evaluated in order to increase the confidence level. One way to evaluate the WRF performance in producing the prediction was carried out by analyzing the diurnal cycles of rainfall over Java and its surroundings using the results of WRF predictions implemented in SADEWA and GSMaP data for one year period (Maret 2014 - Februari 2015). Equitable Threat Score (ETS) and Bias Score were used to evaluate the results of WRF prediction. The contrasting diurnal cycles between Java island and its surrounding seas could be well simulated by the WRF model, both the amount and the frequency of the rainfall. However, the phase of diurnal cycle from the WRF prediction was two hour ahead and the amplitude of the simulated diurnal cycle was higher than the observation. The low ETS score indicated that the WRF prediction was not satisfactory and the high bias score meant that the WRF results were often overpredicted. The results also showed that the WRF predictions could not simulate the effects of MJO (Madden-Julian Oscillation) on the diurnal cycles of rainfall over Java. |
