Caption: Wind effects on a hill. Computer simulation of the line contours of a hill (at centre) and the path of wind over it. Wind direction is arrowed. Wind speed and force is colour-coded: red is highest, blue is lowest. A circular eddy is seen beneath the hill (lower right). Wind erosion and snowdrift modelling are some applications of this computer study. This research is conducted at the wind tunnel Centre Scientifique et Technique des Bati- ments (CSTB), Nantes, France. The Centre can also accommodate in its wind tunnel scaled-down models of whole towns, bridges and rockets, to be tested in winds of more than 200 km per hour. Rain, snow, intense sunlight and heat can also be simulated.
