Jet streams are fast-moving, high-altitude air currents that can influence weather patterns and the flight paths of airplanes. They typically flow from west to east and are strongest during the winter months. Chinooks are warm, dry winds that occur on the eastern slopes of the Rocky Mountains. Valley breezes are local winds that occur when warm air rises and is replaced by cooler air from a nearby valley. Anticyclones are high-pressure systems that typically bring clear skies and calm weather. None of these choices accurately describe the high-elevation "rivers" of air that travel at speeds of 120-240 kilometers per hour from west to east, so the correct answer is C) Jet streams.
