Abstract Quantifying uncertainty in simulations of surface wind speed (SWS) has significant implications for its applications. Here, we examine the SWS changes from 6th coupled model intercomparison project (CMIP6) outputs, and analyzed simulation uncertainties CMIP6 both historical period future projections. The results show that trend interannual variability are underestimated CMIP6. over most Northern Hemisphere will reduce by 4%–6% under high emission scenario last 21st Century, whereas it increase 6%–10% South America Southeastern Pacific. Over land, majority projection is dominated uncertainty, followed internal uncertainty. ocean, greatly influenced variability, with accounting around 20% total late century.

ABSTRACT The geographical uniqueness of the Qinghai–Tibet Plateau (QTP) determines its significance as ‘Asia's Water Tower’. It is expected that climate change in this area will cause extreme weather occurrences, stress water resources and increase vulnerability ecosystems future. However, precise quantitative impact on QTP remains uncertain. In study, using coupled model intercomparison project (CMIP) phase 6 multi‐model data a distributed time‐variant gain hydrological (DTVGM), we examined spatiotemporal attributes hydrology across under various socioeconomic progress trajectories greenhouse gas emission scenarios (SSP1‐2.6, SSP2‐4.5, SSP3‐7.0 SSP5‐8.5). Over next 80 years, an overall warming trend was observed QTP, accompanied by decrease annual total resources. drier arid regions, wetter are humid regions future QTP. Runoff 74.92% region, evaporation 84.93% from 2020 to 2099. SSP5‐8.5, precipitation rate −6.22 mm/10a, runoff −8.84 mm/10a. After year abrupt (2052–2064), became significantly faster. approximately 58.00% surface runoff. Unlike trend, displayed fluctuating upward pattern, with average 2.78 Spatially, variations dry–wet conditions more evident, showing substantial noteworthy northeastern plateau. southeastern region Yarlung Tsangpo River Basin, rates were notably higher than those other regions. Moreover, there significant surge areas adjacent glaciers. conclusion, study offers valuable insights into decision‐making concerning developmental region.

Abstract In the context of climate warming, runoff changes in Tianshan Mountains vary widely across basins, with both increasing and decreasing trends. However, underlying mechanisms remain to be elucidated due complexity response components (rainfall runoff, snowmelt glacier runoff) change. Here, we quantified effects historical (1982–2015) precipitation temperature on its projected future (2016–2100) 25 basins diverse coverage Mountains. A multivariate calibration scheme was used constrain hydrologic model generate reasonable component partitioning. Our results indicate that responses are highly correlated extent at basin scale. Future trends moderately glacierized depend largely magnitude warming: tending decrease under low warming scenario increase high scenario. contrast, is expected increased precipitation. Moreover, contribution R negligible (<5%) most by end this century (2071–2100), posing a challenge stability regional water supplies.

Abstract The quantification of uncertainties in runoff over the Tibetan Plateau (TP), simulated by land surface models (LSMs), is paramount importance for effective water resources management within this region. However, interactions processes on runoff, where effectiveness one process depends chosen scheme another, have rarely been studied. To address gap, we conducted ensemble simulations with Noah‐MP (Noah multiparameterization) LSM varying optional parameterization schemes six and quantified sensitivities to these processes. Results showed that TP was most sensitive RUN (runoff‐groundwater) process. interplay FRO (frozen soil permeability) accounted up 30% variation annual mean TP's permafrost regions. VEG (dynamic vegetation) summer autumn subsurface exceeded 10% southeast TP. In regions among significantly affected observed elevated model errors reduced controllability. Therefore, study underscores imperative need categorize based as a foundational step toward enhancing performance LSMs. Prioritizing improvements physics should be particularly directed marked high interactions.
