Pilots spend a good deal of time in the invisible ether, that is the air mass that surrounds the planet, and are subject to winds found at various altitudes. In light aircraft winds can present problems especially headwinds if on a cross country flight. As such pilots spend a good deal of time on weather. There are a variety of sources available for weather planning but a recently found application presents a moving image of the air mass across the country. It is a map in motion and gives a nice visual overview of the surface wind patterns. It is possible to zoom in on specific areas of the country and may be a useful tool in explaining weather phenomena to students. Plus it is nice just to watch.
