ANALISIS CUACA EKSTREM TERKAIT BENCANA HIDROMETEOROLOGI DI JAYAPURA (STUDI KASUS HUJAN LEBAT TANGGAL 22 FEBRUARI 2014)
Rain with intensity 240.0 mm which occurred on February 22, 2014 in Jayapura, causing floods and landslides in several districts. Weather analysis is required to determine various meteorological factors and to improve preparedness and for reduce the impact of damage and losses due to hydro-meteorological disasters. Data of Sea surface temperatures, sea surface temperature anomaly, southern oscillation index and wind map are visual interpreted. MTSAT Satellite data is processed using SATAID application to generate images and time series graphics of cloud top temperature and cloud top height. Zonal and meridional wind component and relative humidity data are processed using 1.9.0 Grads program to generate vorticity, wind patterns and humidity of each layer of air. Upper air observation data processed using Raob 5.7 application to get the indices of the air stability. The analysis result suggest that clouds development in the Jayapura area caused by Intertropical Convergence Zone, warm sea surface temperatures, high humidity in the air layer and unstable of air thus affects heavy rains in Jayapura. Satellite imagery analysis can suggest the value and patterns that can be used as an indication of clouds development caused heavy rains.
