某些对白垩纪（约1.44亿至6500万年前）洋流的古生物地理重建表明，当时有一股环球热带洋流通过大陆结构向西流动。虽然一些数值气候模式未能在最初的尝试，以模拟这一电流，与耦合的大气-海洋模式，具有相对较高的空间分辨率和晚白垩世大陆分布的模拟表明，环球电流是一个强大的功能，即使在特提斯海道逆转的局部表面电流在南欧亚季风月。
Certain paleobiogeographical reconstructions of ocean currents during the Cretaceous (about 144 to 65 million years ago) suggest that a circumglobal tropical current flowed westward through the continental configuration of that time. Although some numerical climate models failed in initial attempts to simulate this current, simulations with a coupled atmosphere-ocean model with relatively high spatial resolution and a late Cretaceous continental distribution show that a circumglobal current is a robust feature even though local surface currents in the Tethys Seaway reverse during the south Eurasian monsoon months.
