2. FLUX: Sometimes the cloud patches are randomly scattered, an equal oportunity sky, but at other times the clouds will configure themselves into crests and troughs. I learned long ago that clouds' motion can be deceptive, and I've wasted much time standing with sunshine falling somewhere to the left and right of me and sure the clouds were shifting one of those beams my way. It's much easier to tell how the clouds are moving by following a beam of light cast against the hillside than by trying to follow the gaps in the clouds, but when the sky is arranged in long rows of cloud, chances are the clouds are moving in the direction the rows point. The currents that carry the clouds move up and move down and are affected by land contours as they move. As the air lifts it may even form new clouds. One may think the cloud mass is moving on when it is actually forming overhead. As a general rule it's fruitless to chase the sunshine, but in the conditions just described one must eventually cut ones losses and try another hillside.
