Drizzle riddle solved

A recent study by NASA scientists at the Jet Propulsion Laboratory in California and University of Toronto indicates that updrafts are more important than previously thought in determining whether clouds produce drizzle rather than normal-sized raindrops. Such findings will help improve the accuracy of model predictions of rainfall, a challenge for both short-term weather forecasting and longer-term climate projections.
