Chernobyl Wind Stats

The graph describes how often and how strongly the wind blows from different directions over a normal May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 3406 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Chernobyl, located 67 km away (42 miles). There are insufficient recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Chernobyl blows from the NE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Chernobyl. Converseley, 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. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each May) and blows offshore just 12% of the time (3 days in an average May). Over an average May winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Chernobyl
