Abstract On January 24th – 25th, 2017, Borneo Vortex has occurred that started to form at 00.00 UTC and caused the extreme rain in some areas of West Borneo. It recorded 154.1 mm/day heavy Ketapang regency, part region indicated as effect Vortex. The objective this study was determine activity phenomenon triggers Conducted data for obtained from ECMWF reanalysis parameters such vorticity, divergence, vertical velocity, humidity transport. Those used providing an overview atmospheric...
<p class="AbstractEnglish"><strong>Abstract:</strong> As a natural resource that is vital in supporting human life, the evaluation of availability water resources an urgency determining and projecting condition surplus or deficit Wilayah. There are various methods evaluating area, one method has high level significance Thornthwaite Mather balance method. Water analysis was carried out 3 Wilayahs Java Island which have monsoonal rain types, including Bandung, Begawan Solo...
The differences of altimetry in the Pacific Ocean and Indian causes Indonesia Throughflow or commonly called ITF. altimerty will have variation when ENSO (El Nino Southern Oscilation) occur. data from AVISO is used to find out how much influence variations that indicator particular difference between western eastern Ocean. When El occured, be lower than while opposite condition occurs La Nina happened higher These affect transport
The region situated along the southern coast of Papua Island exhibits a considerable likelihood upwelling, which is distinguished by higher amounts chlorophyll-a concentration.The present study examined variability upwelling phenomena spanning period 25 years (1998-2022) through utilization satellite-derived data obtained from Ocean-Colour Climate Change Initiative (OC-CCI).Apart concentration, significant amount suspended sediment contamination, as indicated observations Rrs 555.Upon...
Fluktuasi curah hujan dipengaruhi berbagai faktor lokal hingga global. Kompleksitas kondisi atmosfer Indonesia membuat distribusi di wilayah memiliki keunikan tersendiri. Curah adalah salah satu cuaca yang secara langsung dapat mempengaruhi ketersediaan air tanah. Pada penelitian ini penulis menggunakan sampel pada daerah dengan tipe ekuatorial dan monsunal. Kemudian akan diteliti bagaimana temporal periode 2000-2010. Distribusi tanah (KAT) tersebut. Metode perhitungan digunakan untuk...
Intisari Madden Julian Oscillation (MJO) merupakan osilasi gelombang submusiman di wilayah tropis yang berpropagasi ke arah timur dari Samudera Hindia melewati Benua Maritim Indonesia (BMI) hingga Pasifik. Propagasi MJO dapat meningkatkan konvektivitas dan curah hujan pada dilewatinya. Lampung salah satu BMI bagian barat berbatasan dengan sebagai tempat awal kemunculan MJO. Posisi tersebut menyebabkan perbedaan insolasi antara daratan lautan secara diurnal sehingga siklus ikut berperan dalam...
Interannual variability of sea surface height (SSH) in western Pacific Ocean and eastern Indian occurs as a result the ENSO phenomena. This affects SSH difference between both those oceans. In normal condition, is higher than which causes current that passes through Indonesia known Indonesian Throughflow (ITF). study used geostrophic currents data from 1993 to 2015 obtained AVISO satellite altimetry determine condition represented by temperature (SST) anomaly Niño 3.4 NOAA its relation...
Abstract South Sulawesi is one of the provinces in Indonesia which geographically a marine-based area with huge potential marine resources. In sea resources exploration activities are often found obstacles caused by variability weather and climate that affect condition waters. Limited availability data waters Province has difficulties analyzing identifying conditions these The use MODIS Aqua satellite Altimetry can be used as solution analysis identification water conditions. this study...
ABSTRACTMaluku and Halmahera Sea are the entry paths for Indonesian Throughflow (ITF). This study examined variation of their current speed, direction, transport during ENSO phases on La Nina in 2010-2011 El Nino 2015-2016. The data used were Marine Copernicus reanalysis u v components velocity at 155 m 266 depth. processed by using GrADS to see direction speed as well calculating ITF transport. During Nina, both depths found eddy patterns. When occurred, currents Maluku was different from...
Dua puluh persen kerusakan daerah pesisir di Indonesia diakibatkan oleh perubahan lingkungan dan abrasi. Perubahan garis pantai terjadi dari waktu ke bersaaman dengan aktivitas gelombang. Provinsi Jawa Tengah termasuk salah satu lokasi prioritas nasional untuk fokus kegiatan penanggulangan bencana Lokasi yang dipilih adalah Kabupaten Demak, Kendal, Kota Semarang. Penelitian ini ditujukan mengkaji mengenai pengaruh gelombang terhadap menggunakan SWAN, yaitu aplikasi model numerik perairan...
Intisari Jawa Timur merupakan wilayah yang memiliki variasi curah hujan dipengaruhi oleh fenomena cuaca global dan regional seperti Dipole Mode, El Nino Southern Oscillation (ENSO), Intertropical Convergence Zone, Madden Julian Oscillation, monsun. Topografi beragam juga menjadi faktor memengaruhi di daerah Timur. Berbagai indeks digunakan untuk melihat aktivitas-aktivitas tersebut, DMI aktivitas NINO 3.4 ENSO, Indeks RMM MJO, WNPMI dan, AUSMI Pada penelitian ini analisis spektral dengan...
<p class="Abstract">Sea Breeze Front (SBF) is one of the important components sea breeze circulation, which plays role in coastal area’s atmospheric dynamics. SBF causes significant changes temperature and humidity profiles initiates updrafts that induce convective activity. This study aims to determine characteristics its impact on convection activity using Doppler weather radar west coast area South Sulawesi during dry season. identification utilized PPI CMAX products detect clouds...
The existence of current circulation which flowing from the Pacific Ocean to Indian passing through Indonesia causes a connection between those two oceans.That will be affected if there is global scale disruption such as occurrence ENSO (El Nino Southern Oscillation).The cause sea surface temperature (SST) variability in oceans.This study examines about SST eastern and western at trend differences regions directly connected by that called Throughflow.This utilized data 1982 2015 obtained...
Abstract A long-term reliable sea surface temperature (SST) satellite data record is requisite resources for monitoring to understand climate variability. Creating a especially variability requires combination of multiple products. Consequently, missing issues are inevitable. Hence, DINEOF (Data Interpolating Empirical Orthogonal Functions) has been applied attain complete and coherent multi-sensor SST with EOF-based technique by reconstructing the data. Unfortunately, can lead large...
