- This article reviews the current literature on the implications of the Belt and Road (B&R) Initiative for Chinese multinational enterprises (CMNEs) and calls for further empirical investigations of the motivations, processes, and consequences of the expansion of CMNEs into B&R countries. We posit that the rapid expansion of CMNEs in these countries indicates assets, rather than liabilities, for the county of origin. Empirical studies in this special issue provide new insights into what is "Chinese" about Chinese foreign direct investment in B&R countries and how the "assets of origin" may play a role in CMNEs' expansion in B&R countries.

- Snow and frozen soil are important factors that influence terrestrial water and energy balances through snowpack accumulation and melt and soil freeze-thaw. In this study, a new land surface model (LSM) with coupled snow and frozen soil physics was developed based on a hydrologically improved LSM (HydroSiB2). First, an energy-balance-based three-layer snow model was incorporated into HydroSiB2 (hereafter HydroSiB2-S) to provide an improved description of the internal processes of the snow pack. Second, a universal and simplified soil model was coupled with HydroSiB2-S to depict soil water freezing and thawing (hereafter HydroSiB2-SF). In order to avoid the instability caused by the uncertainty in estimating water phase changes, enthalpy was adopted as a prognostic variable instead of snow/soil temperature in the energy balance equation of the snow/frozen soil module. The newly developed models were then carefully evaluated at two typical sites of the Tibetan Plateau (TP) (one snow covered and the other snow free, both with underlying frozen soil). At the snow-covered site in northeastern TP (DY), HydroSiB2-SF demonstrated significant improvements over HydroSiB2-F (same as HydroSiB2-SF but using the original single-layer snow module of HydroSiB2), showing the importance of snow internal processes in three-layer snow parameterization. At the snow-free site in southwestern TP (Ngari), HydroSiB2-SF reasonably simulated soil water phase changes while HydroSiB2-S did not, indicating the crucial role of frozen soil parameterization in depicting the soil thermal and water dynamics. Finally, HydroSiB2-SF proved to be capable of simulating upward moisture fluxes toward the freezing front from the underlying soil layers in winter.

- Historical soil moisture (SM) variations, trends, and their driving factors remain scarce for the area of Tibetan Plateau (TP), which hinders putting a sensible assessment of the current and future ecological drought risk into perspective. Here, we report the first three century-long regional summer (July-August) SM reconstruction for the southeastern TP during 1691-2007 CE using a paleoclimate proxy, that is, tree-ring delta O-18. The SM reconstruction, which explained 60.9% of the actual variance, revealed that an abrupt wet-to-dry change occurred in 1884. After 1884, SM exhibited a decreasing trend and enhanced variability, and dry summers occurred more frequently. In particular, the variability in SM reached an unprecedented level after the 1950s relative to that during the past three centuries. A structural equation model and running correlation analysis revealed that SM variation was mainly controlled by precipitation rather than temperature. This indicates that the anthropogenic-related weakening of the Indian summer monsoon played a more dominant role in SM changes after 1884 than the increase in temperature. If the SM variability is to be further increased in the future, it may undermine ecosystem stability and forest health. The results of this study are significant for predicting ecological drought in ecologically vulnerable regions such as the High Asia.

- In distributed hydrological modeling, surface air temperature (Tair) is of great importance in simulating cold region processes, while the near-surface-air-temperature lapse rate (NLR) is crucial to prepare Tair (when interpolating Tair from site observations to model grids). In this study, a distributed biosphere hydrological model with improved snow physics (WEB-DHM-S) was rigorously evaluated in a typical cold, large river basin (e.g., the upper Yellow River basin), given a mean monthly NLRs. Based on the validated model, we have examined the influence of the NLR on the simulated snow processes and streamflows. We found that the NLR has a large effect on the simulated streamflows, with a maximum difference of greater than 24% among the various scenarios for NLRs considered. To supplement the insufficient number of monitoring sites for near-surface-air-temperature at developing/undeveloped mountain regions, the nighttime Moderate Resolution Imaging Spectroradiometer land surface temperature is used as an alternative to derive the approximate NLR at a finer spatial scale (e.g., at different elevation bands, different land covers, different aspects, and different snow conditions). Using satellite-based estimation of NLR, the modeling of snow processes has been greatly refined. Results show that both the determination of rainfall/snowfall and the snowpack process were significantly improved, contributing to a reduced summer evapotranspiration and thus an improved streamflow simulation. ©2016.

- Recent soil moisture (SM) reconstructions revealed plunging trends and enhanced SM-temperature couplings over the last two decades in dry regions. However, how SM changed and whether the land-atmosphere interaction was intensified over time in humid regions remained unknown. Here we reported the first six-century-long regional summer SM reconstruction (1360-2000 CE) in western Europe (WE) using three individual tree-ring delta O-18 chronologies in England and France. A sharp wet-to-dry change occurred around 1820, earlier than 1850-1900 CE, the commonly used historical baseline of anthropogenic climate changes. Enhanced coupling of SM-temperature followed, with stronger summer sea level pressure anomalies in dry years after the 1820s. Our results reveal that the hotter-drier regime has also become more frequent in humid WE under global warming.
