Five annual climate cycles (1998-2002) are simulated for continental Africa and adjacent oceans by a regional atmospheric model (RM3). RM3 horizontal grid spacing is 0.44° at 28 vertical levels . Each of 2 simulation ensembles is driven by lateral boundary conditions from each of 2 alternative reanalysis data sets. One simulation downs cales National Center for Environmental Prediction reanalys...

Methods Definitions for feasibility and applicability were based on the AGREE instrument. The FE design was a parallel, two-arm before-after descriptive study in 2 convenience samples, Principal sites, invited by the 6 WHO Regional Offices and voluntary Complementary sites of selected HCFs, conducted over 4 phases. A suite of tools to assist implementation, assessment, training, education and f...

Abstract The increase in computational resources has enabled the emergence of multi-model ensembles convection-permitting regional climate model (CPRCM) simulations at very high horizontal resolutions. An example is CORDEX Flagship Pilot Study on “Convective phenomena resolution over Europe and Mediterranean”, a set kilometre-scale an extended Alpine domain. This first-of-its-kind ensemble, for...

Abstract. Gravity waves play a significant role in driving the semiannual oscillation (SAO) of zonal wind tropics. However, detailed knowledge this forcing is missing, and direct estimates from global observations gravity are sparse. For period 2002–2018, we investigate SAO four different reanalyses: ERA-Interim, JRA-55, ERA-5, MERRA-2. Comparison with SPARC climatology quasi-geostrophic winds ...

Soil temperature is a crucial parameter in surface emissions of carbon, water, and energy exchanges. This study utilized the soil 836 national basic meteorological observing stations over China to evaluate three products. data from Meteorology Administration Land Data Assimilation System (CLDAS), European Centre for Medium-Range Weather Forecasts (ERA-Interim), Global (GLDAS) during 2017 are ev...

Western disturbances (WDs) develop as extra-tropical low-pressure systems over the Mediterranean and lose their frontal structure they move eastward toward India. The effect of aerosols on microphysical characteristics precipitation clouds associated with WDs in February 2016 was investigated west coast India adjacent Arabian region. This research highly depends era interim reanalysis ensemble ...
