This impressive composition showing curvy clouds stretching across the better part of the sky was photographed from Northamptonshire, U.K. in mid winter. Such wave clouds commonly occur when stable air is forced to rise over hills and mountains or after the passage of a cold front. The altostratus clouds that resulted on this day were formed in relatively stable atmospheric conditions -- vertical motion was minimized. This was one of those special days when at first glance what seemed like an unimaginative sky turned into something quite breathtaking.
