Ardmore Wind Statistieken, Winter gemiddelde vanaf 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical northern hemisphere winter. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ardmore, located 20 km away (12 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Ardmore blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Ardmore. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (4 days each northern hemisphere winter) and blows offshore just 13% of the time (1 days in an average northern hemisphere winter). During a typical northern hemisphere winter winds stronger than >40kph (25mph) are expected on 19 days at Ardmore
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
