Abstract

Power spectra of longitudinal and vertical components of wind velocity have been measured over a variety of terrain types: uniform, inhomogeneous and urban. The result shows that the spectral shapes and peaks of u‐spectra are sensitive to local terrain, while those of w‐spectra are not affected by changes in roughness surface.

## Abstract The standard deviations of wind velocity components are calculated and compared based on the measurements of turbulence fluctuations over three underlying surfaces: uniform, inhomogeneous and urban. Statistical analysis shows that there are the differences between them which prove the i

## Abstract From the high frequency velocity measurements of the AIDJEX Lead Experiment we derive estimates of u and w spectra and uw cospectra both above Arctic leads and over relatively smooth pack ice. The measurements over the leads are unique for two reasons: they were made within a geophysica

An indirect method of estimating the surface heat flux from observations of vertical velocity variance at the lower mid-levels of the convective atmospheric boundary layer is described. Comparison of surface heat flux estimates with those from boundary-layer heating rates is good, and this method se
