Based on the fact that wind speed tends to increase as we go from onshore offshore, aim of this work is perform an analysis a Romanian coastal sector located near Danube Delta. Over course 20 years (2001–2020), in situ observations and reanalysis data (ERA5 MERRA-2) local conditions were evaluated meteorological renewable point view. This evaluation includes two sites (Galati Tulcea), one site ...

Precipitable water vapor (PWV) product with high accuracy and spatiotemporal resolution is important for climate change research. Hourly PWV products a can be provided by global navigation satellite system (GNSS) reanalysis data. The National Aeronautics Space Administration (NASA) the European Center Medium-Range Weather Forecasts (ECMWF) have recently released their of Modern-Era Retrospectiv...

Global navigation satellite system (GNSS) radio occultation (RO) receivers onboard the recently-launched COSMIC-2 (C2) constellation provide an unprecedented number of high vertical resolution moisture profiles throughout tropical and subtropical atmosphere. In this study, distribution variability water vapor was investigated using specific humidity retrievals from C2 observations compared to c...

The meteorological reanalysis data has been widely applied to derive zenith tropospheric delay (ZTD) with a high spatial and temporal resolution. With the rapid development of artificial intelligence, machine learning also begins as high-efficiency tool be employed in modeling predicting ZTD. In this paper, we develop three new regional ZTD models based on least squares support vector (LSSVM), ...

ERA5 is the fifth-generation atmospheric reanalysis of European Center for Medium-Range Weather Forecasts, with high spatiotemporal resolution and global coverage. However, reliability simulating extreme precipitation events still unclear over China. In this study, 12 indices a comprehensive quantitative distance between simulation observation were used to evaluate from three fundamental aspect...

This study aimed to determine the mean temperature trends in south-southeast region of Mexico during historical period 1980–2014, as well future periods 2021–2040, 2041–2060, and 2081–2100, recommended by IPCC. Additionally, sought identify climate change scenario that is most closely aligned with socio-environmental conditions zone has greatest impact on region’s average temperature. The downs...

The influence of sea-surface temperature (SST) on the lower troposphere and stratosphere in tropical, middle, polar latitudes is studied for 1980–2019 based MERRA2, ERA5, Met Office reanalysis data, numerical modeling with a chemistry-climate model (CCM) middle atmosphere. variability SST analyzed according to ERA5 while atmospheric investigated MERRA2 data. Analysis sea surface trends data rev...

High relative humidity (RH) and temperature extremes can occur simultaneously persist for periods of time, resulting in serious harm to human health, especially humid regions. Here, the case Gan River Basin, we used air RH from observed ERA5 reanalysis datasets construct apparent investigate characteristics heat cold waves. Heat waves showed increasing trends 1961 2018 (particularly 1997 2018),...
