Abstract

This research was conducted to determine the accuracy of the application of the Kain-Fritsch (KF) scheme in the Weather Research and Forecasting (WRF) model for rainfall prediction in the city of Palembang. Information about rainfall prediction is needed to help smooth community activities in various fields. Input data used in the WRF model are Global Forecast System (GFS) data with a spatial resolution 0f 0,250 x 0,250 and temporal resolution an 3 hours for the period December 2018 – February 2019. Comparative data in this research are TRMM satellite data and observation station data BMKG for data validation observations on the surface. Observation points representing Palembang City are Kenten, Sultan Mahmud Badaruddin II Airport (SMB II) and Sriwijaya Bukit Besar University (UNSRI BB). Verification is done to find out the accuracy of WRF prediction data with the dichotomy and error deviation methods. And verification results show WRF prediction data has good accuracy in predicting rain events. However, the KF scheme does not indicate perfect forecast data criteria.
