VANCOUVER – When a very cold air mass flows over a warmer body of water it creates an effect known as ‘Arctic sea smoke.’

Jerry Mason captured the effect earlier this week on Okanagan Lake, when the air temperature was about -18 degrees in the Okanagan Valley.

Global BC meteorologist Kristi Gordon says the little tornadoes that can be seen on the surface of the lake also form when it is very windy.

The moist air can be seen rising from the lake and up to the low clouds above.
