Abstract Floods are a major contributor to natural disasters in Sumatra. However, atmospheric conditions leading floods not well understood due, among other factors, the lack of complete record floods. Here, 5 year flood for Sumatra derived from governmental reports, as crowd-sourcing data, based on Twitter messages and local newspapers’ is created used analyze phenomena responsible It shown, that majority analyzed floods, convectively coupled Kelvin waves, large scale precipitation systems...

Abstract The characteristics of diurnal variation precipitation in terms amount (PA), frequency (PF), and intensity (PI) over Sumatra have been investigated using rain‐gauge data from 186 stations. Mean PA PF show spatial variations significantly affected by the terrain elevation stations' distance to west coastline Sumatra. A slightly larger appear middle western sections Barisan mountains, which mean PI is smaller these regions. Most stations with large rainfall also frequencies, indicated...

Accurate and current rainfall analysis is crucial for planning development in the new capital city of Indonesia (IKN). This study examines effect Madden-Julian Oscillation (MJO) on variability IKN using a 20-year dataset Integrated Multi-Satellite Retrievals GPM (IMERG) version 6 automatic weather station (AWS) data. The analyzes flood events by examining information provided National Agency Disaster Countermeasures (BNPB) from 2008 to 2022 contribution MJO these events. findings indicate...

The measured rain rate, raindrop size distribution (DSD), and the ITU-R model over frequency range from 1-100 GHz have been used to elucidate cumulative rainfall rate variability of attenuation at Kototabang. Rain DSD are recorded ground-based optical gauge disdrometer measurements, respectively. Considerable differences between data observed small time percentage. specific obtained measurement shows diurnal variation with largest in morning hours. This characteristic is due spectra events...

Abstract. Regional variability of raindrop size distribution (DSD) along the Equator was investigated through a network Parsivel disdrometers in Indonesia. The were installed at Kototabang (KT; 100.32° E, 0.20° S), Pontianak (PT; 109.37° 0.00° Manado (MN; 124.92° 1.55° N) and Biak (BK; 136.10° 1.18° S). It found that DSD PT has more large drops than other three sites. DSDs four sites are influenced by both oceanic continental systems, majority data matched maritime-like reported previous...

This study is a preliminary assessment of the latest version Global Satellite Measurement Precipitation (GSMaP 08) data, which were released in December 2021, for Indonesian Maritime Continent (IMC), using rain gauge (RG) observations from 2021 to June 2022. Assessments carried out with 586 stations point-to-pixel approach through continuous statistical and contingency table metrics. It was found that coefficient correlation (CC) GSMaP 08 products against RG varied between low (CC =...

Abstract Background The Suban area of Curup Rejang Lebong is a tourist region in Bengkulu Province, Indonesia, close to the active Ketaun and Musi faults, which are segments Sumatra Fault System (SFS).
