Abstract. This paper investigates the global stratospheric Brewer–Dobson circulation (BDC) in ERA5 meteorological reanalysis from European Centre for Medium-Range Weather Forecasts (ECMWF). The analysis is based on simulations of mean age air, including full spectrum, with Lagrangian transport model CLaMS (Chemical Model Stratosphere), driven by winds and total diabatic heating rates. ERA5-base...

This letter addresses the link availability issue in satellite-based free space optical (FSO) communications. In particular, we present an accurate analysis for estimation of presence clouds and atmospheric turbulence. For this purpose, a meteorological ERA-Interim database, produced by European Center Medium Range Weather Forecast (ECMWF), is investigated. The obtained data is, then, used to a...

Surface incident solar radiation (Rs) is a key parameter in many climatic and ecological processes. The data from satellites and reanalysis have been widely used. However, for reanalysis, Rs data has been shown to have substantial spatial bias, and the time span of reliable satellite Rs is too short for climatic and ecological studies. Combining reanalysis and satellite data would be an effecti...

High-resolution underway shipboard atmospheric and oceanic observations collected in Drake Passage from 2000 to 2009 are used to examine the spatial scales of turbulent heat fluxes and flux-related state variables. The magnitude of the seasonal cycle of sea surface temperature (SST) south of the Polar Front is found to be twice that north of the front, but the seasonal cycles of the turbulent h...

Abstract The aim of this study is to verify 2-meter temperature and mean sea level pressure forecasts from BSC-DREAM8B V2.0 model, which a short-term numerical forecasting model against observed data the Iraqi Meteorological Organization & Seismology constitution modelled (ERA-Interim) reanalysis European Centre for Medium Range Weather Forecasts (ECMWF) period 1-3 June 2012 four selected s...

The Tropical Meteorology Project at Colorado State University currently issues seasonal forecasts for Atlantic basin hurricane activity in early April, June, and August. This paper examines the potential for issuing an additional seasonal forecast on 1 July, using a two-predictor forecast model. The two predictors are selected from the ECMWF Interim Re-Analysis (ERA-Interim) and explain over 60...
