Statistiques de Vent de Army Beach, moyennes sur Mars depuis 2006
The figure illustrates how commonly and how strongly the wind blows from different directions through a typical March. 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 2220 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Army Beach, located 32 km away (20 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 prevailing wind at Army Beach blows from the NNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Army Beach. Converseley, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each March) and blows offshore 15% of the time (5 days in an average March). In a typical March wind stronger than >40kph (25mph) was forecast for only a single days at Army Beach
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.
