Mammatus Clouds

14th Jan 2011

I took about 20 shots with a 50mm lens to best give some scale to what I saw and included some rooftops also for this.
I instantly contacted the local newspapers who were un-interested, but a tv channel showed one photo during a live weather broadcast seen here...Fred Talbot from ITV.


These cloud formations are listed in the top 10 rarest cloud formations to be found anywhere and are mainly associated with a strong storm
Mammatus may appear as smooth, ragged or lumpy lobes and may be opaque or semitransparent. Because mammatus occur as a grouping of lobes, the way they clump together can vary from an isolated cluster to a field of mamma that spread over hundreds of kilometers to being organized along a line, and may be composed of unequal or similarly-sized lobes. The individual mammatus lobe average diameters of 1–3 km and lengths on average of 0.5 km. A lobe can last an average of 10 minutes, but a whole cluster of mamma can range from 15 minutes to a few hours. They usually are composed of ice, but also can be a mixture of ice and liquid water or be composed of almost entirely liquid water.
