Abstract The altimeter waveform data of satellite TOPEX/Poseidon over Hulun lake are analyzed. It is proved that satellite altimeter waveforms over lake have oceanlike characteristics. Most of the altimeter waveforms are peaks or spikes during the frozen period in winter, while the wave energy is lower than that in summer owing to the influence of snow and ice covering the lake surface.
