Abstract Changes to precipitation patterns and extremes over the Nepalese Himalayas were examined using a high‐resolution, station‐based daily dataset, Asian Precipitation‐Highly Resolved Observational Data Integration Towards Evaluation (0.05° × 0.05° APHRODITE) from 1951 2007. The annual statistics of extreme across Nepal show significant increase since end 20th century. However, seasonal mean shows remarkable decrease in western Nepal, particularly 1980, forming an east–west division...
The reliability of satellite precipitation products is important in climatic and hydro-meteorological studies, which especially true mountainous regions because the lack observations these areas. Two recent rainfall estimates (SREs) from Global Precipitation Measurement (GPM)-era—Integrated Multi-Satellite Retrievals for (IMERG-V06) gauge calibrated Satellite Mapping (GSMaP-V07) are evaluated their spatiotemporal accuracy ability to capture extreme events using 279 stations southern slope...
Abstract Timely and effective seasonal climate prediction is crucial to reduce the losses from hydro-meteorological disasters by providing early warning. Evaluating model’s performance essential for their accurate interpretation implementation. Here, we examined precipitation forecast of South Asian monsoon using second-generation finite-volume version Flexible Global Ocean-Atmosphere-Land system (FGOALS-f2), a seamless system. The hindcast skill was assessed multiple metrics lead times 0 2...
The remediation of river water using activated carbon is one the economic solutions to overcome shortage problem. Nanoporous-activated carbons (ACs) were synthesized from pistachio shell powder phosphoric acid as activating agent. Various impregnation ratios used activate precursor and then carbonized at 400℃ for three hours in a nitrogen atmosphere. characterized Scanning Electron Microscopy (SEM), Raman scattering, Fourier Transform Infrared Spectroscopy (FTIR), semi-quantitative surface...
Precipitation plays vital roles in the global water cycle, knowledge of spatial and temporal variation precipitation is essential to understanding extreme environmental phenomena such as floods, landslides, drought. In this paper, integrated characteristics during 1980–2016 over Nepal along with seasonal elevation dependency were examined for three different regions country using Multi-Source Weighted-Ensemble (MSWEP) product. The distribution mean annual varies significantly highest...
Nepal’s rugged topography, unstable young geological formations, and fragile rocks make the country highly vulnerable to water-induced hazards such as landslides, soil erosion, debris torrents. Hilly watersheds settlements in hills river banks are naturally during heavy rainfall. The landslide EVO project selected two areas, one Bajedi landslides Bajura district, another Sunkuda Bajhang district of Nepal. Automatic rain gauges were installed, data recorded for 2019 2021. best-fit trend lines...
Abstract Sub‐seasonal to seasonal (S2S) prediction provides an extended range of lead time for decision‐makers across multiple sectors. S2S forecast is crucial a country that are susceptible hydro‐meteorological disasters like Nepal. However, requires assessment with reliable datasets before its application. Since, Nepal lacks dense station network, multi‐source precipitation estimates (MPEs) the obvious alternatives. Therefore, using classical evaluation metrics and extreme indices, this...
This study evaluates the Integrated Multi-satellite Retrievals from Global Precipitation Measurement (IMERG) final product’s ability to represent extreme precipitation against 310 observations Nepal between 2015 and 2017. Additionally, Method of Object-based Diagnostic Evaluation (MODE) analysis was also performed analyze IMERG capture actual spatial distribution rainfall extremes. Both datasets show events are mostly concentrated at southern low land areas country. MODE tool further...
