The measurements of profiles of wind speed and air temperature in the atmospheric surface layer above bare ice surface in the circumference of the Yamato Mountains were carried out under neutral and unstable conditions in December. 1973. The results are summarized as follows: 1) The value of aerodynamic roughness parameter (Z_0) was constantly 0. 085 cm independent on wind speed. https://wwlnlxw1hk4nn.dsiblogger.com/67921142/cd137-4-1bb-signalosome-complexity-is-a-matter-of-trafs
