Long description

This shows a map of the British Isles. Contour lines join regions of equal wind speed (maximum winds velocity). The contours are 0.5 m per s apart. The wind contours are roughly circular around a point in the SE of England (near Oxford). The circular regions extend to the north of England, thereafter the contours are part of a very roughly closed curve, covering land and the sea between England and Ireland. The lowest speed near Oxford is 21.5 m per s. The highest is on a contour that passes near the Shetland Isles in the north, 30 m per s. It is set on a grid of squares that are 100 x 100 km and coded with 2 letters. England, Scotland and Wales are on a grid 7 x 10 squares and Ireland on a region 4 x 5 squares.
