Enhanced warming in semi‐arid regions has received much attention since it was first proposed, but the primary driver of this phenomenon remains unknown. This study applied dynamical adjustment to surface air temperature and partitioned the warming into two separate components: a thermodynamically forced component and a dynamically induced component. The results show that the mean amount of thermodynamic warming in the Northern Hemisphere in the study period 1902–2011 was 1.36 °C/109 years and that the amount of dynamic warming was 0.14 °C/109 years. In the mid‐latitude zones of Asia, Europe, and North America, the thermodynamic warming was 1.60, 1.19, and 1.32 °C/109 years, respectively, and the corresponding dynamic warming was 0.26, 0.14, and 0.09 °C/109 years. Obviously, higher thermodynamic temperature warming was observed in semi‐arid regions, suggesting …
