Wind research. Researchers above a tank of water used to simulate a vertical column of air. Salt water and freshwater in the tank mimic cold air and hot air respectively. A platform (at back) positioned just above the surface of the water carries instruments to monitor and record movements in the water. Photographed at the National Centre for Meteorological Research, Toulouse, France.
