In which direction do autumn gales most likely blow on Lake Ontario?

The correct answer indicates that autumn gales on Lake Ontario predominantly blow from the southwest through to the northwest. This phenomenon is influenced by seasonal weather patterns, where cold air moving over the relatively warmer waters of Lake Ontario creates instability and can lead to strong winds.

During the autumn months, the transition from summer warmth to cooler air can result in significant pressure differences, especially as cold fronts move in from the northwest. These conditions often generate gales that can travel across the lake from the southwest, which is also closer to prevailing wind patterns observed in this region.

Other potential answers may not accurately reflect the general wind direction associated with autumn weather on Lake Ontario. It's essential to understand the prevailing meteorological factors and geographical influences that contribute to wind patterns, as these can significantly affect boating, fishing, and other outdoor activities on the lake.
