北极和青藏高原上空存在着丰富的混合相云。它们的季节循环、垂直结构和云辐射效应（包括短波CRE、长波CRE和净CRE）的显著差异意味着对气候系统的不同影响。混合相云的最大发生率出现在北冰洋春末冬初，而在青藏高原则出现在夏季。在寒冷季节（9 ~ 5月），地面混合相云引起的CRE对北极地区有较强的增暖作用，而夏季青藏高原地区则有较强的降温作用。北冰洋逆温的存在限制了混合相云及其相关的水汽凝结物和近地面垂直辐射加热廓线的分布，而青藏高原没有这种逆温，因此青藏高原云诱导的大气加热廓线具有较大的垂直对比度和季节变化。
Abundant mixed-phase clouds exist over the Arctic and the Tibetan Plateau. Salient differences in their seasonal cycle and in their vertical structure and cloud radiative effects (CREs, which includes shortwave CRE, longwave CRE and net CRE) imply different influences on the climate system. The maximum incidence of mixed-phase clouds appears during the late spring and early winter over the Arctic Ocean, but it appears during the summer over the Tibetan Plateau. The surface mixed- phase-cloud-induced CRE exerts a strong warming effect over the Arctic during the cold season (from September to May), in contrast to the strong cooling effect over the Tibetan Plateau during the summer. The existence of temperature inversion over the Arctic Ocean confines the mixed-phase clouds and associated cloud hydrometeors and vertical radiative heating profile at the near surface, while over the Tibetan Plateau there is no such a temperature inversion, and hence the cloud-induced atmospheric heating profile exhibits both larger vertical contrast and more seasonal variation over the Tibetan Plateau.
