Abstract Urban land expansion is one of the most conspicuous aspects urbanization and has profound impacts on regional climate change. Most studies, however, focus its surface temperature, possible effects atmospheric humidity are less known. By examining changes in Yangtze River Delta urban agglomeration China during 1961–2014, we find a prominent dry island (UDI) effect this agglomeration, as characterized by reduced increased vapor pressure deficit core area. In past decades, UDI been significantly intensified rapid expansion. contributes to around half decrease increase areas. These particularly stronger wet hot summer relatively weaker cold winter. We suggest that should be considered future planning, landscape design, change assessment mitigation.

Tree planting is a prevalent strategy to mitigate urban heat. cooling efficiency (TCE), defined as the temperature reduction for 1% tree cover increase, plays an important role in climate it regulates capacity of trees alter surface energy and water budget. However, spatial variation more importantly, temporal heterogeneity TCE global cities are not fully explored. Here, we used Landsat-based land (LST) compare TCEs at reference air level across 806 explore their potential drivers with boosted regression (BRT) machine learning model. From results, found that spatially regulated by only leaf area index (LAI) but variables anthropogenic factors especially city albedo, without specific variable dominating others. such difference attenuated decrease cover, most pronounced midlatitude cities. During period 2000-2015, than 90% analyzed showed increasing trend TCE, which likely explained combined result increase LAI, intensified solar radiation due decreased aerosol content, vapor pressure deficit (VPD) albedo. Concurrently, significant afforestation occurred many showing city-scale mean 5.3 ± 3.8% from 2000 2015. Over growing season, increases were estimated on average yield midday 1.5 1.3°C tree-covered areas. These results offering new insights into use adaptation warming planners may leverage them provide benefits if primarily planted this purpose.
