Statistiques de Vent de Aropaonui, moyennes sur Mars depuis 2006
This image illustrates how frequently 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 implies the strength, with the darkest shade of 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 Aropaonui, located 24 km away (15 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Aropaonui blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Aropaonui. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of 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 (the lightest shade of blue) about 20% of the time (6 days each March) and blows offshore 41% of the time (11 days in an average March). In a typical March wind stronger than >40kph (25mph) was expected for only a single days at Aropaonui
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.
