Heinz EngelhardtWeather is one of the main sources of uncertainty and risk in many agricultural systems (for climate see Box III.2.2). Common weather phenomena on the earth include wind, rain, snow, fog; and less common phenomena include storms or tropical cyclones, heat and cold waves. Almost all familiar phenomena occur in the troposphere.
