Look at Okanagan Lake project itself into the sky, as a cloudless space. Storm is trying to move in from the west (and from the northeast), with no luck. Terrace Mountain, in the distance, is pushing the energy of the incoming front into a projection of its own shape in the centre of the image, projecting the storm within the cloudless space as a mountain-sized fall of rain.
The pressure driving at the mountain from the west, causes smaller projections to form in the projected lake space between the mountain and the mountain of rain in the sky. One forms every five minutes, and then drifts into the negative space of the lake.In this climate, in the negative space of the Coast Mountains to the west, negative space makes our weather. Notice as well how as a result of the projections of the earth into the sky when the rain falls it doesn’t fall on Terrace Mountain but at the head of the watershed in the centre of the image below, which then carries it down to the lake.
The forces that made this deep inland fjord through such underground water pressure systems are still at work. This scene is their projection on the sky.
