The variability of surface air temperature is of great importance for both society and the environment, is impacted by global warming and local-scale changes. In the arid eastern part of Washington state of USA, substantial urbanization has transformed the Tri-cities into the state’s third-largest urban cluster. This study utilizes a combination of in situ observations and reanalysis datasets to investigate the influence of land use changes on the region’s 2-meter temperature, revealing local effects that compensate for the background global warming. Within the urban fabric, distinct microclimates have emerged due to varying land use, establishing unique relationships between greenness and temperature alterations caused by land use transitions. Notably, our findings demonstrate that the observed compensating signal in the temperature of farmland locations is primarily attributed to local vegetation increases. Through these observations, this research highlights the urban impacts on local climate, offering valuable insights into the complexities surrounding land use and its consequences on the environment.

城市对中型干旱城市长期季节性趋势影响的复杂性

地表气温的变化对社会和环境都非常重要，受到全球变暖和局部变化的影响。在美国华盛顿州干旱的东部地区，大规模的城市化已将三联市转变为该州第三大城市群。这项研究结合了就地观测和再分析数据集，以调查土地利用变化对该地区 2 米温度的影响，揭示补偿背景全球变暖的局部影响。在城市结构中，由于土地利用的不同，出现了独特的小气候，在土地利用转变引起的绿化和温度变化之间建立了独特的关系。值得注意的是，我们的研究结果表明，观察到的农田温度补偿信号主要归因于当地植被的增加。通过这些观察，这项研究强调了城市对当地气候的影响，为了解土地利用的复杂性及其对环境的影响提供了宝贵的见解。
