The wind and weather conditions that you encounter during your outings on the Great Lakes are governed by the passage of low and high pressure systems. We’ll examine the life-cycle and structure of a low pressure system, including cold fronts, warm fronts and stationary boundaries. You will also learn what type of weather to expect with the passage of a low pressure system, and how surface weather charts can be used to tell how fast and in what direction weather systems are moving relative to your own position.
