Abstract

Studying the Martian atmosphere is important in planetary science. The boundary layer turbulence is characterized at the Zhurong location using spectrum analysis, two-dimensional spectrum, and similarity theory. The results reveal that the atmospheric temperature and wind at the Zhurong location are consistent with Kolmogorov’s “-5/3” turbulence laws. The atmospheric movement at the Zhurong location has four usual weather scales: 50 m, 100 m, 150 m, and 200 m. The atmospheric refractive index structure parameters, and thus the effect of turbulence on the light propagation, at the Zhuong and Insight locations are 3 or 4 orders less than at the Perseverance location. The sensible heat flux values in the Zhurong location is mainly in the range of 0-10 W/m²and increases during measurement. The clear seasonal variability in heat flux flow with greater value in spring and summer than in autumn and winter is revealed at both the Zhuong and Insight locations.
