Systematic cold biases exist in the simulation for 2 m air temperature Tibetan Plateau (TP) when using regional climate models and global atmospheric general circulation models. We updated albedo Weather Research Forecasting (WRF) Model lower boundary condition Global LAnd Surface Satellite Moderate-Resolution Imaging Spectroradiometer products demonstrated evident improvement TP. It is large overestimation of winter spring WRF model that resulted biases. The overestimated was caused by...
Soil temperature, an important indicator of climate change, has rarely explored due to scarce observations, especially in the Tibetan Plateau (TP) area. In this study, changes observed five meteorological variables obtained from TP between 1960 and 2014 were investigated using two non-parametric methods, modified Mann–Kendall test Sen's slope estimator method. Analysis annual series shown that surface (0 cm), shallow (5–20 deep (40–320 cm) soil temperatures (ST), mean air temperature (AT),...
Abstract The freeze–thaw changes of seasonally frozen ground (SFG) are an important indicator climate change. Based on observed daily freeze depth SFG from meteorological stations the Tibetan Plateau (TP) 1960 to 2014, spatial–temporal characteristics and trends in were analyzed, relationships between them climatic geographical factors explored. Freeze–thaw a regional scale assessed by multiple regression functions. Results showed multiyear mean maximum depth, duration, start date, thaw end...
The Tibetan Plateau (TP) is covered by thousands of lakes which affect the regional and global heat mass budget with important implications for current future climate change. However, TP performance contemporary lake models over have not been quantified to date. We utilise 3-yr observations from Ngoring Lake, largest in Yellow River source region TP, investigate typical properties lake–air boundary layer evaluate a simplified scheme Community Land Model version 4.5 (SLCLM) as one most...
Abstract. Lakes are sensitive indicators of climate change. There thousands lakes on the Tibetan Plateau (TP), and more than 1200 them have an area larger 1 km2; they respond quickly to change, but few observation data available. Therefore, thermal condition plateau under background warming remains poorly understood. In this study, China regional surface meteorological feature dataset developed by Institute Research, Chinese Academy Sciences (ITPCAS), MODIS lake temperature (LST) buoy were...
Abstract. Understanding the intricate hydrological interactions between lakes and their surrounding watersheds is pivotal for advancing research, optimizing water resource management, informing climate change mitigation strategies. Yet, these complex dynamics are often insufficiently captured in existing models, such as bi-direction surface subsurface flow. To bridge this gap, we introduce a novel lake–watershed coupled model, an enhancement of Simulator Hydrological Unstructured Domains....
Permafrost has significant impacts on climate change through its strong interaction with the system. In order to better understand permafrost variation and role it plays in change, model outputs from Phase 5 of Coupled Model Intercomparison Project (CMIP5) are used present study diagnose near‐surface Tibetan Plateau (TP), assess abilities models simulate present‐day (1986–2005) project future TP under four different representative concentration pathways (RCPs). The results indicate that...
ABSTRACT The Tibetan Plateau (TP) lakes are sensitive to climate change due ice-albedo feedback, but almost no study has paid attention the ice albedo of TP and its potential impacts. Here we present a recent field experiment for observing lake in TP, evaluate applicability Moderate Resolution Imaging Spectroradiometer (MODIS) products as well parameterizations. Most observed albedos on <0.12, clear blue is only 0.075, much lower than reported previous studies. Even that covered with snow...

Abstract Frozen soil is widely distributed over the Tibetan Plateau (TP) and has significant impacts on regional climate ecosystem. However, Community Land Model version 5 (CLM5.0) produces evident cold bias in frozen simulation TP. In this study, an improved vegetation emissivity scheme a gravel hydrothermal have been implemented into CLM5.0 model, their synergistic influences TP systematically addressed revealed. Results show that adopting scheme, both can remarkably reduce simulated by...
Abstract Previous studies show that some soil moisture products have a good agreement with in situ measurements on the Tibetan Plateau (TP). However, response to precipitation variability different is yet be assessed. In this study, we focus across weekly decadal time scales satellite observations and reanalyses. The of differs between products, large uncertainties observed for variations accumulated precipitation. Using June 2009 as an example, mean anomalous varies by up 25% products....

Since the 1990s, Qinghai-Tibetan Plateau (QTP) has experienced a strikingly warming and wetter climate that alters thermal hydrological properties of frozen ground. A positive correlation between degradation in permafrost or seasonally ground (SFG) long been recognized. Still, predictive relationship historical wetting under conditions not yet well demonstrated, despite expectation it will become even more important because precipitation over QTP projected to increase continuously near...
Abstract Changes in soil temperature (ST) and moisture (SM) are essential for climate change ecosystem assessments. Previous investigations on the ST SM Tibetan Plateau (TP) mainly based situ observation satellite products.
