Abstract. This study compares trends in the Hadley cell (HC) strength using different metrics applied to ECMWF ERA5 and ERA-Interim reanalyses for period 1979–2018. The HC is commonly evaluated by derived from mass-weighted zonal-mean stream function isobaric coordinates. Other include upper tropospheric velocity potential, vertical mid-troposphere, water vapour transport lower troposphere. Sev...

This study evaluates a numerical weather prediction model as tool for wind resource assessment in complex terrain and how the simulations are affected by selection of initial boundary conditions various grid resolutions. Two global reanalyses, ERA-Interim ERA5, four resolutions, 27 km, 9 3 km 1 have been considered. The compared to hub-height measurements. ERA5 forced were found provide improve...

Offshore wind farms are a current area of interest in Australia due to their ability support its transition renewable energy. Climate reanalysis datasets that provide simulated speed data frequently used evaluate the potential proposed offshore farm locations. However, there has been lack comparative studies accuracy predictions from different for Australian waters. This paper assesses distribu...

Understanding East Asian monsoon (EAM) has been a crucial issue due to its socio-economic effects on one-fifth of the world’s population and interactions with global climate system. However, reliabilities reanalysis data are still uncertain at varying temporal spatial scales. In this study, we examined correlations differences for reanalyses weather observations suggested best EAM region. The t...

The arid and semiarid regions of Uzbekistan are sensitive vulnerable to climate change. However, the sparse very unevenly distributed meteorological stations within region provide limited data for studying region’s variation. aim this work was evaluate performance European Centre Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA)-Interim ERA5 products fields near-surface temperature, humi...

Abstract. Aeolus wind products became available to the public on 12 May 2020. In this study, observations, L-band radiosonde (RS) data, and European Centre for Medium-Range Weather Forecasts fifth-generation atmospheric reanalysis (ERA5) data were used analyze seasonality of product performance over China. Based Rayleigh-clear Mie-cloudy quality effective detection was verified, results showed ...
