| Popis: | The horizontal wind around the Argus Island tower, near Bermuda, was measured to establish the characteristic disturbance of the natural airflow caused by the tower. Observations were taken during periods of light to moderate southerly wind with near-neutral thermal stability. To obtain a generalized picture of the disturbance field, the raw observations were converted to ratios of the presumed undisturbed wind computed from the logarithmic profile. The field of disturbance thus demonstrated was highly distinctive and was rather insensitive to variations in undisturbed wind speed. It showed two jets of accelerated air: one above the platform extending upward at least 15 m and the other one below extending down to the water surface. A ‘nose’ of decelerated air extended about 15 m upwind of the enclosed platform, and a wake of reduced velocity was formed to leeward. The purpose of the work was to locate suitable sites for installing outrigged micrometeorological instruments for determining fluxes of momentum, heat, and water vapor. Two regions 18 m upwind, one above and the other below the platform, were judged to be favorable. |
