On the Kalamazoo River this weekend, Michigan residents will kayak down the sparkling waters and cast their lines for smallmouth bass. The relaxing summer day will bear little resemblance to July 25, 2010, when a ruptured pipeline spewed a million gallons of crude oil into a nearby creek. Five years and billions of cleanup dollars after the worst inland oil spill in U.S. history, the river is largely revitalized. Resuscitated wetlands hug the river, while three new boat launches and man-made rapids draw paddlers, fishers and weekenders.
a result, the angle of the frontal boundary is not as severe as a cold front and the warm air climbs slowly over the cooler air. This produces layered clouds like stratus and nimbostratus clouds. Far in advance of the front cirrostratus and cirrus clouds form. Warm fronts form clouds that cover a large area and create rain or snow events that
Lenticular clouds, technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction. Where stable moist air flows over a mountain or a range of mountains, a series of large-scale standing waves may form on the downwind side. Lenticular clouds sometimes form at the crests of these waves. Under certain conditions, long strings of lenticular clouds can form, creating a formation known as a wave cloud. Power pilots tend to avoid flying near lenticular clouds because of the turbulence of the rotor systems that accompany them, but sailplane pilots actively seek them out.
