"Making Waves," by Eugenie Samuel Reich. New Scientist, 29 November 2003, pages 30-33.
This article discusses ideas of an atomspheric physicist who believes that the accuracy of mathematical models used for weather prediction could be improved by injecting the models with a dose of randomness. The phenomenon that led him to this idea is known as inertia-gravity waves, which are produced as the earth's gravitational field drags the atmosphere around. His experiments with liquids spinning in a bucket "have convinced him that forecasters should replace some of the painstakingly calculated values of temperature and pressure in their models with random numbers to stand in for the unknown effect of inertia-gravity waves."
