Abstract Sublimation waves are periodic, linear and transverse bedforms that grow by sublimation of icy substrates under turbulent winds. They occur in different environments of the Earth and other planets, where the climate is favorable to sublimation. Their morphological and kinematic characteristics (wavelength, migration velocity, characteristic time of formation) depend on the environmental conditions in which they develop (atmosphere viscosity, wind speed, sublimation rate). To highlight these relations, we designed a theoretical model for their formation, based on models previously designed for dissolution bedforms. From a linear stability analysis of the model, we derived a dispersion relation and three scaling laws. These are validated by comparison with measurements available for two natural terrestrial examples (Blue Ice Areas of the Antarctic ice sheets and ice caves) and with new measurements in a laboratory experiment. They are applied to linear bedforms, of hitherto unknown origin, that we identified on the Martian North Polar Cap. We thus demonstrate that sublimation waves are convenient geomorphic markers to constrain surface compositions, atmospheric properties, climates, and winds on terrestrial ice sheets and other icy planetary surfaces.

升华波：冰冷的行星表面和风之间相互作用的地貌标志

摘要 升华波是周期性的、线性的和横向的床形，在湍流风下通过冰层升华而生长。它们发生在地球和其他行星的不同环境中，那里的气候有利于升华。它们的形态学和运动学特征（波长、迁移速度、形成的特征时间）取决于它们发展的环境条件（大气粘度、风速、升华率）。为了强调这些关系，我们根据之前为溶出床型设计的模型，设计了它们形成的理论模型。从模型的线性稳定性分析中，我们导出了色散关系和三个缩放定律。这些通过与两个自然陆地示例（南极冰盖和冰洞的蓝冰区）的测量值和实验室实验中的新测量值进行比较来验证。它们被应用于迄今为止未知来源的线性床型，我们在火星北极帽上发现了这种床型。因此，我们证明了升华波是一种方便的地貌标记，可以限制陆地冰盖和其他冰冻行星表面的表面成分、大气特性、气候和风。
