We Call It Mariah

Returning to Earth: I came across a mesmerizing web page yesterday that illustrates the flow of wind over the United States at the current moment.

Yesterday, there was a vortex where a great deal of wind was headed -- starting in west central Indiana in the morning and working its way east past Columbus. This morning, you could make out the contours of the Appalachians from the decreasing wind speed on the windward side and a marked increase in speed with a slight change in direction on the leeward side of the chain.

Clicking on the map allows you to zoom in on the area where you click.
