Mountain precipitation, characterized by complex processes and marked spatial heterogeneity, has long been a key focus and challenge in hydrometeorology and global change research. Although satellite remote sensing, ground-based radar retrievals, and reanalysis precipitation products have been continuously improving, they still suffer from insufficient spatial resolution and considerable uncert...
The petrochemical industry is a foundational sector supporting national economic development and also a key part of China's industrial landscape, characterized by concentrated energy use and prominent emissions. Due to complex feedstock routes and long production chains, the industry has long faced challenges such as unclear accounting boundaries and difficulties in pinpointing key emission red...
Tropospheric winds form a cornerstone of the Earth's weather and climate system, directly driving global energy balance and moisture transport, and influencing the evolution of extreme weather events. However, due to the spatial and temporal sparseness of upper-air observations, long-term changes in tropospheric wind speed remain substantially uncertain, posing challenges for accurate...
Academician Chen Deliang’s Team of Tsinghua University Reveals That Climate Change and Inequality Intensify Global Migration PressureClimate change is emerging as one of the most severe human challenges of the 21st century, profoundly reshaping the global pattern of population migration. The frequent occurrence of extreme climate events exacerbates food, health, and water resource crises, forc...
Nighttime light (NTL) remote sensing is a vital proxy for quantifying the intensity and spatial distribution of human activities. However, early DMSP-OLS data suffer from saturation and blurring effects, while high-quality NPP-VIIRS data are only available from 2012 onward, lacking direct comparability between the two systems, which limits long-term time-series studies. Existing cross-sensor ca...
Against the backdrops of global drought and warming, whether plants can maintain a match between the water supply capacity of sapwood and the transpiration demand of leaves has become a key factor affecting plant survival, which directly influences ecosystem carbon and water cycles. The Huber value (vH; the ratio of sapwood area to leaf area) is an important trait characterizing this supply-dem...
Against the backdrop of global warming, tropical cyclones (TCs) are exhibiting complex responses to climate change. On the one hand, cyclone intensification rates are accelerating and rapid intensification events have increased markedly; on the other hand, the distribution of tropical cyclone lifetime maximum intensity (LMI) is undergoing systematic adjustments. These phenomena indicate that th...
Recently, Academician Chen Deliang from the Department of Earth System Science (DESS) at Tsinghua University, in collaboration with the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences, Alibaba Group, China Electric Power Research Institute of State Grid Corporation of China, Global Energy Interconnection Group Co., Ltd. and other institutions, has developed HydroTrace, ...
