Accurate extreme precipitation information is crucial for disaster risk management, social and economic development security, climate change research. Taking the Yangtze River Delta (YRD), China, a high-impact area of precipitation, as an example, this study evaluates spatiotemporal performance in latest fifth-generation reanalysis dataset from European Centre Medium-Range Weather Forecasts (i....

Abstract The climate of High Mountain Asia (HMA) has changed in recent decades. While the temperature is consistently increasing at a higher rate than global warming rate, precipitation changes are inconsistent, with substantial temporal and spatial variation. Climate will have enormous consequences for hydroclimatic extremes. For altitudes HMA, which significant source water large rivers Asia,...

Abstract. We previously reported a notable warm bias in ERA5-Land soil temperature permafrost regions that was supposedly being caused by an underestimation of snow density. In this study, we implemented and evaluated new multi-layer scheme the land surface ERA5-Land, i.e., HTESSEL, with revised densification parameterizations. compared temperatures from numerical experiments observations origi...

Abstract Globally, thunderstorms are responsible for a significant fraction of rainfall, and in the mid-latitudes often produce extreme weather, including large hail, tornadoes damaging winds. Despite this importance, how global frequency their accompanying hazards has changed over past 4 decades remains unclear. Large-scale diagnostics applied to climate models have suggested that intensity is...

Abstract. Information about the spatiotemporal variability of soil moisture is critical for many purposes, including monitoring hydrologic extremes, irrigation scheduling, and prediction agricultural yields. We evaluated temporal dynamics 18 state-of-the-art (quasi-)global near-surface products, six based on satellite retrievals, models without data assimilation (referred to hereafter as “open-...

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...

Abstract Surface incident solar radiation ( R s ) is important for providing essential information on climate change. Existing studies have shown that the values from current reanalyses are significantly overestimated throughout China. The European Centre Medium-Range Weather Forecasts (ECMWF) recently released fifth generation of atmospheric reanalysis (i.e., ERA5) with a much higher spatiotem...
