Many windy days are the result of passing storm fronts. In addition, daytime heating and evening cooling of the desert floor may act to create local winds. Daytime warm air rises and is replaced with cooler air that drains through surrounding canyons, mountain passes, and arroyos. Windblown air pulls more moisture from the soil than would otherwise evaporate in still air. Hot, dry air blowing around plants and people dehydrates them, creating acute water needs. This is where good water management becomes important.
