We in the Weather world talk a lot about the Lakes, and their “effect(s)” on us…and for good reason. All things work together, and it’s up to us “scientist types” to figure out how and how much. Lake Ontario is notorious for bringing downwind locations (usually east or southeast) a ton more snow than other areas that are just hit by the storm itself, whose winds get the Lake into action after the fact. The Lake also has a cooling effect on us in Spring time, as the air heats up from longer days, but the Lake keeps things cooler (and more tranquil, thunderstorm-wise), downwind too.
But, do you realize that if the winds aren’t “strong enough” to see visible effects, there are still things happening, where the Lake (and any lake) is interacting with the atmosphere above it, but not visible to the eye.
In that vein, here’s a fairly technical article (you are forewarned!) on the topic of lake/air interaction in general…not specific to Ontario, but it does actually include data regarding other local lakes!
Read on, if so inclined…
