Precipitation is a key component of the hydrological cycle and one most important variables in weather climate studies. Accurate reliable precipitation data are crucial for determining trends variability. In this study, eleven different datasets compared, six reanalysis five observational datasets, including ERA5 WFDE5 from ECMWF family, to quantify differences between widely used identify thei...

This work continues the presentation and evaluation of the Ocean–Land–Atmosphere Model (OLAM), focusing on the model’s ability to represent radiation and precipitation. OLAM is a new, state-of-the-art earth system model, capable of user-specified grid resolution and local mesh refinement. An objective optimization of the microphysics parameterization is carried out. Data products from the Cloud...

Abstract This study evaluates changes in simulated Pacific climate between two ECMWF re-analyses; the ERA Interim (ERAI) and newest ERA5. Changes Integrated Forecasting System (IFS) possibly sea surface temperature result greatly reduced discrepancies ERA5’s ice water path (IWP), radiative fluxes precipitation relative to satellite-based observational products. IWP shows largest percentage chan...

In this paper, Japan Meteorological Agency (JRA-55) reanalysis and observational rainfall datasets from the National Climate Center (NCC) of China, as well satellite Tropical Rainfall Measuring Mission (TRMM), Global Precipitation Climatology Project (GPCP), International Satellite Cloud (ISCCP), are used. The correlation coefficient fast Fourier transform (FFT) low-pass filter also used, in or...

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. Satellite observations (International Cloud Climatology Project (ISCCP), 1983–2009) of linear trends in cloud cover are compared to those global precipitation (Global Precipitation (GPCP) pentad V2.2, 1983–2009), investigate possible cause(s) the both and precipitation. The spatial distributions total characterized primarily by a broadening major ascending zone Hadley circulation. Our...

In this study, the authors compare six different rainfall datasets for South America with a focus on their representation of extreme rainfall during the monsoon season (December–February): the gauge-calibrated TRMM 3B42 V7 satellite product; the near-real-time TRMM 3B42 V7 RT, the GPCP 18 daily (1DD) V1.2 satellite–gauge combination product, the Interim ECMWF Re-Analysis (ERA-Interim) product; ...
