Widespread spring vegetation greening (inferred by LAI) in the Northern Hemisphere leads to additional summer soil moisture (SM) deficits through increasing transpiration. Meanwhile, vapor pressure deficit (VPD) has also been rising, which can increase atmospheric evaporative demand. However, extent and magnitude of influence these two factors on SM changes have not elucidated. Here, based state-of-the-art reanalysis remote sensing data, we use three statistical methods quantify contributions LAI VPD deficit. The results show that contributes more change than southwestern northern regions North America, northeastern Europe, central southeastern Asia, covering 13.4% vegetated areas despite certain drying. are great significance for climate adaptation enhancement surface water management.

Abstract The impact of soil moisture (SM) and vapor pressure deficit (VPD) on gross primary productivity (GPP) variability in ecosystems is a topic significant interest. Previous studies have predominantly focused real-time associations between SM, VPD, carbon uptake, attributing SM as the principal driver GPP due to its direct indirect effects through VPD. Using an information theory-based process network approach, we discovered that influence past mediated emerges across tropical regions. VPD conditions directly also affect alongside GPP, which subsequently impacts variability. Examining land-atmosphere feedback using theory reveals but not reverse. These causal structures explain consistent decline with increasing trends observed regions, are trends. Our findings emphasize importance considering by when analyzing complex land-vegetation-atmosphere interactions.

Abstract In August 2022, Pakistan experienced an unprecedented precipitation event that caused significant damage. Analysis of the observations reveals this extreme rainfall is primarily driven by anomalous atmospheric zonal advection, resulting in water vapor concentration Pakistan.

Abstract Efforts to predict long‐term changes in continental runoff at both global and basin scales generally remain ambiguous. Here we use a reconstruction Bayesian statistical method narrow uncertainties projections from the latest generation of climate models. Three representative tropical river basins are used illustrate application showcase potential for substantial reduction modeling uncertainty. Yet, results fairly sensitive selected thus highlighting need reliable homogeneized gridded data sets or discharge measurements. Moreover, models do not account water withdrawals, whose effect on observed should also be removed order detect attribute hydrological change. Finally, more importantly, most fail capturing recent decrease ratio, which may highlight either model deficiencies increasing derivation over basins.
