Surface Air Temperatures

Winter temperatures are less severe when waters are open due to relatively warm surface waters

Island temperatures are generally cooler (warmer) than the mainland in summer (winter)

Lake Ice Formation

Warming surface water temperatures

Surface winds

modify ice location, form, and distribution

Warming surface air temperatures (winter and/or summer)

Increased mixing of water layers brings relatively warm deep waters (during winter) to the surface

Increased wind and wave action

Amount of ice cover from previous season - less (more) allows longer (shorter) period of absorbing solar radiation
