自20世纪90年代末以来，全球地表温度变暖速度的降低引起了人们的广泛关注，并引起了极大的争议。然而，在同一时期，大多数先前的研究都报告了青藏高原(TP)变暖的加剧。本文利用1980年至2014年期间的均一化温度资料，进一步分析了青藏高原及周边地区的气温变化趋势，发现青藏高原低于4000 m的青藏高原增温速率自20世纪90年代末以来开始减缓，这与中国整体和全球气温变化趋势基本一致。然而，对于TP高于4000 m的区域，这种升温速度的下降直到2000年代中期才出现。这种延迟变暖的间歇期可能与近年来区域辐射、能量和陆地表面过程的变化有关。
A reduction in the warming rate for the global surface temperature since the late 1990s has attracted much attention and caused a great deal of controversy. During the same time period, however, most previous studies have reported enhanced warming over the Tibetan Plateau (TP). In this study we further examined the temperature trend of the TP and surrounding areas based on the homogenized temperature records for the period 1980–2014, we found that for the TP regions lower than 4000 m the warming rate has started to slow down since the late 1990s, a similar pattern consistent with the whole China and the global temperature trend. However, for the TP regions higher than 4000 m, this reduction in warming rate did not occur until the mid‐2000s. This delayed warming hiatus could be related to changes in regional radiative, energy, and land surface processes in recent years.
