青藏高原和印度洋均对我国气候有重要影响，研究高原和印度洋的热力状况及其耦合关系对全面了解我国的天气现象具有重要意义.利用1981 — 2010年(30 a)欧洲中心ERA-interim的青藏高原和印度洋温度资料，以及NCEP/NCAR的垂直速度和风速资料，分析了青藏高原地气温差和印度洋海气温差的特征及其相互影响.结果表明，高原冬、夏季地气温差有所区别：冬季地气温差呈东北-西南向的带状分布，在高原中部、西南边界喜马拉雅山脉地区和东南边界出现了较大的负值中心，其他地区均为正值；夏季地气温差均为正值，远大于冬季.在印度洋，海气温差冬、夏均为正值，EOF1空间分布均出现正负交替的现象，但冬季为东西向带状分布，夏季为西北-东南向分布.高原和印度洋相互影响且互相制约：在冬季，印度洋对高原地气温差有正反馈，高原对印度洋则有负反馈，夏季相反.本结果可为进一步研究青藏高原和印度洋对亚洲气候的共同作用提供参考.
