Mammatus 1

A mammatus formation seen in Leeds, Tue 1 Apr 2003

Mammatus [Leeds, 1 Apr 2003; FinePix4800Z]

Cumulus mammatus clouds, seen on an April evening from Leeds. Not a particularly fine example, but the best we have at the moment.

Mammatus clouds hang from the underside of a cumulonimbus cloud, and hence are always associated with storms. They indicate great instability in the atmsophere, with many convection currents. To see them well, it's best to have a low, unobscured sun to cast shadows.
