Preliminary meteorological results for 1992 West Coast Scotland Experiment
This memo documents preliminary meteorological results from the 1992 West Coast Scotland Experiment, a joint US/UK radar ocean imaging experiment. Measurements of wind speed and direction are reported for both phases of the experiment covering the periods from June 7--13 and from June 19--25. The measurements were obtained using a Campbell Scientific CR10 Datalogger and R. M. Young model 03001-5 anemometer and wind wane. The anemometer has a resolution of 0.1 m/s and the wind vane 1[degrees], but motion of the ship platform reduces the precision of the direction measurements to [+-]10[degrees]. Data were downloaded to an IBM PC-AT for final storage and analysis. The anemometer was mounted at a height of 10 meters above the mean water surface on top of a mast located at the bow of the Royal Marine Auxiliary Service (R.M.A.S.) tug, [open quotes]Cairn[close quotes]. The Cairn was moored at the center of the experiment site at 57[degrees]7.13755[close quote] N, 5[degrees]44.88521[close quote] W in the Sound of Sleat. nominally 200 meters from the ship track. Wind velocity and direction were recorded at a sample rate of 0.2 Hz, and the averaged value was output every 10 minutes from approximately 2 hours before the start of the first run to 2 hours after the end of the last run. Data are plotted in the following pages in 2 formats for a quick visual summary of the daily wind conditions. The top plot gives wind velocity (m/s) and direction (degrees true) vs. time given in minutes relative to the start of the first run which is designated as [open quotes]T[close quotes]. The lower plot gives a polar plot of the same data with velocity on the radial axis and direction on the azimuthal axis. The final two plots give a summary of the wind speed vs. direction for phase 1 (June 7--13) and phase 2 (June 19--25).
