| Summary: | Randomly selected periods of COADS archive wind data in U.S. Mid-Atlantic 2° square summary areas are a basis for estimates of wind variability between decades of wind summary periods. Similar treatment of coastal observations provide estimates of decades variability which is compared with the COADS summaries variability. The variability is expressed in terms of speed and direction components of the wind as vector parameters. Spatial variability is also examined to determine the representativeness of 2 ° COADS spatial summaries in coastal gradients of wind variation. The representativeness of decade COADS summaries, to define intra-regional scales of climate variability, is tested by comparing observed change with change expected from theoretical boundary layer processes. Periods of northern hemisphere air temperature variation are used as indicators of climate variability and these periods are used to evaluate the resolution of such variability with COADS wind data. Wind constancy computed from COADS wind summaries is used to evaluate possible long period changes of wind over the North Atlantic. |
