Extended Data Fig. 1: Wind profiles.

(a) Mean horizontal wind speed with elevation for a fixed friction velocity (u_* = 0.3 m/s) and grain size (d = 100μm) for the six bodies of interest using the empirical relation in Supplementary Information Text S4. The grain center is denoted with a black line. (b) Dimensionless presentation of (a), where \({u}_{x}^{+}=u/{u}_{* }\) and z⁺ = zu_*/υ.
