Assessing the impacts of land use and land cover change (LUCC) on regional climate is essential for understanding land-atmosphere interactions and for designing climate adaptation and mitigation strategies. Using the weather research and forecasting (WRF) model, we examined how different land use and land cover patterns affect regional climate in t...

China has experienced unprecedented urbanization since the 1980s, resulting in substantial climatic effects from local cities to broad regions. Using the Weather Research and Forecasting model dynamically coupled to an urban canopy model, we quantified the summertime climate effects of urban expansion in China's most rapidly urbanizing regions: Bei...

Atmospheric humidity is usually drier in cities than the surrounding rural areas, a phenomenon known as the urban dry island (UDI) effect. However, the response of atmospheric humidity to hot weather in urban versus rural settings remains unknown. Using long‐term summer (June–August) observations at 1662 stations over 1961–2020, we find that China...

Dry‐ and wet‐bulb temperature (Td and Tw) are usually to define heatwaves (HWs) which have been enhanced under anthropogenic climate change (ACC) and urbanization. However, responses of various types of HWs (i.e., dry HWs, only high Td; humid HWs, only high Tw; hybrid HWs, both high Td and Tw; total HWs, high Td or Tw), to ACC and urbanization rema...

Green space is an important adaptation strategy against urban thermal environmental change. However, the impact of the spatiotemporal changes in green space on urban mesoscale meteorology and human thermal comfort has been understudied. Here, we incorporated gridded urban green fraction (GF) corresponding to 2016 and 2020 in central Wuhan into the...

Fine particulate matter (PM 2.5 ) is a major source of air pollution and exerts serious impacts on human health. The 3D urban landscape patterns can significantly affect the diffusion and emissions of PM 2.5 . However, studies on the relationships between 3D urban landscape patterns and PM 2.5 pollution across different seasons remain understudied....

Context Densification and outward expansion are two manifestations of urban land-change process. However, the spatiotemporal evolution of urban densification is poorly documented and necessitates in-depth understanding. Objectives This study, using building information spanning 2000–2018 on Wuhan, is focused on: (1) the spatiotemporal evolution of...

Urban morphology exerts a strong influence on urban thermal environments, and local climate zones (LCZs) explicitly link urban morphology with microclimate. However, how temperature, humidity, and thermal comfort vary across different LCZs from a modeling perspective remains understudied. Here, we first developed a high-precision LCZs map of centra...

Wuhan has witnessed unprecedented urban expansion that encroached upon sizable inland lakes. However, the impacts of urban expansion on climate and heat stress for such a city with complex physiographic background (land‐water mosaics) remain understudied. Using a coupled urban‐lake‐atmospheric model, we first examined summer climate responses to ur...

This Special Issue will be launched to celebrate the 70th anniversary of the CUG. The Special Issue aims to highlight the role and contribution of remote sensing in the past 70 years and illustrate the progress and achievements in this field from the CUG’s scientific research groups. This Special Issue is soliciting contributions from people curren...

Under global warming, projected changes in precipitation have shown an asymmetrical shift from light to heavy precipitation over China. However, the role of urbanization in this shift remains unknown. Here, we show that increases in total rainy‐season (May‐September) precipitation over the Yangtze River Delta (YRD) urban agglomeration of East China...

Urbanization may exert a strong influence on both near-surface and atmospheric moisture. However, studies on the effect of urbanization on atmospheric moisture using remotely sensed observations have been infrequently conducted. To fill this research gap, we used remotely sensed and station-based observations to calculate urban–rural differences in...

Understanding the relationships between ecosystem services (ESs) is important for ecosystem management and sustainable development. However, most studies used synergies and trade-offs to infer ESs relationships, while ESs bundles was infrequently involved. Research on the spatiotemporal dynamics and potential drivers of changes of ESs bundles is st...

Food security is closely related to individual livelihood and social stability, and assessing the state of food security is essential for making agricultural policies. Nonetheless multi-scale assessment of national food security state with explicit consideration of availability and access remains to be resolved. In this study, a spatially explicit...

Building morphology has critical impacts on urban environments. However, the association between building morphology and urban environments across different scales and seasons remains understudied. This study investigated the effect of 2D/3D building morphology on seasonal urban climate and air quality in the residential areas (with radii of ≤200 m...

ContextStudies have shown that land use and land cover change (LUCC) has myriad impacts on local and regional climate. Synthesizing the recent findings in this field helps advance landscape ecology and sustainability science in the face of climate change.Objectives To review and synthesize mesoscale modeling-based studies examining the impact of LU...

Changes in land systems have been shown to affect regional climate, but minimal attention has been paid to landscape patterns as adaptation strategies to climate change. In this study, we introduce alternative futures analysis and coupled land-atmosphere modeling to investigate the effect of landscape patterns on moderating projected climate change...

The Grain to Green (GTG) program launched in 1999 by the Chinese government is one of the largest ecological restoration programs ever implemented in the world. Although the GTG program has been demonstrated to affect ecosystem services in the revegetated areas, its impacts on regional climate are seldom reported and poorly understood. Therefore, o...

Under the background of rapid population growth, achieving accurate assessments of crop yields is critical to national policy adjustment and food security. Among all the evaluation methods for crop yields, the Environmental Policy Integrated Climate (EPIC) model is considered to be an effective tool. Since published, it has been widely applied on l...

China's rapid socioeconomic development during the past few decades has resulted in large-scale landscape changes across the country. However, the impacts of these land surface modifications on climate are yet to be adequately understood. Using a coupled process-based land-atmospheric model, therefore, we quantified the climatic effects of land cov...

China is the largest and most rapidly urbanizing nation in the world, and is projected to add an additional 200 million city dwellers by the end of 2030. While this rapid urbanization will lead to vast expansion of built-up areas, the possible climate effect and associated human health impact remain poorly understood. Using a coupled urban-atmosphe...
