This study aims to determine long-term spatial variability of wind and wave characteristics over the Sea Marmara. For this purpose, we produced four different datasets for a period 40 years (1979–2018) using calibrated default-setting SWAN models forced with both CFSR ERA-Interim winds inter-compared. The performance these is examined against height measurements 2015 at Silivri buoy station 27-...

The Botswana High is a prominent mid-tropospheric system that modulates rainfall over subtropical southern Africa, but the capability of global climate model (GCM) to reproduce it remains unknown. This study examines GCM with quasi-uniform resolution (Model Prediction Across Scales, hereafter MPAS) in simulating characteristics High. MPAS applied simulate at 240 km globe for period 1980–2010. r...

This study assessed the performance of two well-known gridded meteorological datasets, CFSR (Climate Forecast System Reanalysis) and CMADS (China Meteorological Assimilation Driving Datasets), three satellite-based precipitation TRMM (Tropical Rainfall Measuring Mission), CMORPH Prediction Center morphing technique), CHIRPS Hazards Group InfraRed Precipitation with Station data), in driving SWA...

The Botswana High is an important component of the regional atmospheric circulation during austral spring, summer and autumn. While high tends to be stronger El Niño weaker La Niña, its direct response Southern Oscillation (ENSO) remains unknown. To that end, a variable resolution global climate model (Model Prediction Across Scales version 7, hereafter MPAS) applied with relatively (48-km grid...

Abstract. Global reanalyses from data assimilation systems are among the most widely used datasets in weather and climate studies, potential vorticity (PV) is invaluable for many studies of dynamical transport processes. We assess how consistently modern represent each other, focusing not only on PV but also process-oriented diagnostics including equivalent latitude calculated PV-based tropopau...

19 flood prone catchments in Kenya, Eastern Africa Flooding is a major natural hazard especially developing countries, and the need for timely, reliable, actionable hydrological forecasts paramount. Hydrological modelling essential to produce but challenging task, poorly gauged catchments, because of inadequate temporal spatial coverage hydro-meteorological observations. Open access global mete...

We have equipped the unstructured-mesh global sea-ice and ocean model FESOM2 with a set of physical parameterizations derived from single-column Icepack. The update has substantially broadened range processes that can be represented by model. new features are directly implemented on unstructured mesh, thereby benefit flexibility comes it in terms spatial resolution. A subset parameter space thr...
