November 2014

Gesundheit!

How and where a cloud releases its load to earth can vary greatly with the type of cloud. In the case of November’s Cloud of the Month, a large Cumulonimbus over the Mongolian Steppe, the precipitation is sudden, heavy and very localised. Here, the rain or hail is falling within an intense downward burst of air, known as a ‘microburst’. It is not unlike a cloud sneeze.

A microburst can be either ‘dry’, when it is just a downward column of intense wind, or ‘wet’, as in James and Sheila’s photograph, when the wind carries heavy precipitation. Like an actual sneeze, a microburst can develop suddenly and with little warning. So when a storm cloud is overcome with the urge to let rip like this, you’ll have to hope it isn’t facing you as it does so.

    Wonderful shot and caught just at the rihjy moment :)
    BTW I love this society because the majority of people do not appreciate clouds because they equate them with rain and bad weather.. BUT.. when you live in a rain-challenged area you learn to appreciate clouds in all their fascinating forms :)
