Intermediate wavelength seasurface height (SSH) undulations over the Pacific plate appear to represent the platform of secondary mantle convection. Several aspects of these intermediate SSH undulations will be addressed, including: 1) analyze the SSH data in the Pacific to determine the presence and nature of the undulations; 2) verify the robustness of the phenomenon by establishing whether the SSh undulations exist on other plates; 3) test the possible mechanisms capable of causing these undulations (e.g. mantle convection).

太平洋板块上的中波长海表高度（SSH）波动似乎代表了次级地幔对流的平台。本文将讨论这些中间超高压波动的几个方面，包括：1)分析太平洋超高压数据，以确定波动的存在和性质；2)通过确定其他板块上是否存在SSh波动来验证该现象的鲁棒性；3)测试引起这些波动的可能机制（例如地幔对流）。
