In the spring, what is the most common type of fog encountered on Lake Ontario?

• A. Advection fog
• B. Radiation fog
• C. Refraction fog
• D. Occlusion fog

Answer: (A)

The most common type of fog encountered on Lake Ontario in the spring is advection fog. This phenomenon occurs when warm, moist air moves over the cooler surface of the lake, causing the moisture in the air to condense into fog. During the spring, air temperatures can warm up significantly while the lake water remains cold from the winter months, creating ideal conditions for advection fog to form. This type of fog can be dense and cover large areas, impacting visibility significantly, which is particularly important for navigation. Other types of fog, such as radiation fog, typically form on clear nights when the ground cools quickly, which is less common over the lake in spring due to the moderating effects of the water temperature. Refraction fog is not generally referenced in meteorological terms, as it pertains to the bending of light rather than the formation of fog. Occlusion fog, associated with weather fronts, is more relevant to transitioning seasons but is not the primary type experienced in the spring on the lake. Therefore, advection fog stands out as the predominant fog type in this specific context.
