Wall Clouds

Wall Clouds Wall clouds form under the rain-free base (bottom) of cumulonimbus clouds. It takes its name from the fact that it resembles a dark gray wall (sometimes rotating) that lowers down from the base of the parent storm cloud, usually just before a tornado is about to form. In other words, it is the cloud from which a tornado spins.     Wall clouds form as the thunderstorm updraft draws in air near the ground from several miles around, including from the nearby rain shaft. This rain-cooled air is very humid and the moisture within it quickly condenses below the rain-free base to create the wall cloud. …

Mammatus

Whoever first exclaimed “The sky is falling!” must have seen mammatus clouds overhead. Mammatus appear as bubble-like pouches that hang on the underside of clouds. As odd as they look, mammatus aren’t dangerous — they simply signal that a storm may be nearby.  When seen in association with thunderstorm clouds, they’re typically found on the underside of anvils.

Young’s Dairy Charity Bike Tour

The Young’s Dairy Charity Bike Tour will be on Saturday, September 10th. The ONE day tour covers several Ohio counties, comprising up to 100 miles, so a large number of ham radio operators will be needed.

There is a bike path route for a portion of the return trip. We are not responsible for tracking riders on the bike path, but we may cover a few key…

Anvil Clouds

An anvil cloud isn’t a stand-alone cloud, but more of a feature that forms at the top of a cumulonimbus cloud.  The anvil top of a cumulonimbus cloud is actually caused by it hitting the top of the stratosphere — the second layer of the atmosphere. Since this layer acts as a “cap” to convection (the cooler temperatures at its top discourage thunderstorms), the tops of storm clouds have nowhere to go but outward. Strong winds high up fan this cloud moisture (so high up that it takes the form of ice particles) out over great distances, which is why anvils can extend outward for hundreds of miles…
