字幕依据：And the greater the temperature difference, the heavier the snow can be. Also, you need enough atmospheric moisture in place to. Get those snow crystals developing and growing in that rising unstable air, and 3, the wind flow over the lake. 6XEb_jH0v2s@1:10
字幕依据：And get this, a lake effect snow machine can just keep going and going for hours and days, generating significant amounts of snow. Very quickly, as long as the main weather ingredients stay in place. Lake effect snow events can be very intense and of long duration, producing snowfall rates up to around 5 inches per hour, creating whiteout conditions and blizzards. 6XEb_jH0v2s@2:16
