Global wind patterns. Historical illustration of global air circulation, 1855. This model was designed by Matthew Fonataine Maury (1806-1873), a US naval lieutenant who was also an oceanographer, meteorologist and cartographer. The model illustrates how global winds are divided into three wind belts in each hemisphere and that atmospheric circulation occurs in cells at mid, low and polar latitudes. Taken from Astra Castra, (Hatton Turner, London 1865).
