Pyrocumulonimbus Clouds theWeather Club Wed, 15/07/2020 - 12:34

Pyrocumulonimbus clouds are thunder clouds created by intense heat from the Earth’s surface. They are formed in a very similar way to cumulonimbus clouds, but the intense heat that results in the vigorous updraft comes from fire, either large wildfires or volcanic eruptions. It is for this reason the prefix ‘pyro’ is used – meaning fire in Latin. Pyrocumulonimbus clouds were reported during the Australian bushfires in late 2019/early 2020 and a number have more recently been observed in Siberia with the Arctic heatwave.

Haboob, Sandstorm or Dust Storm? theWeather Club Wed, 01/07/2020 - 12:39

Haboob was originally the name for a dust or sandstorm in the northern part of the Sudan, most commonly observed between May and September during the afternoon and evening. The name is derived from the Arabian word ‘habb’ meaning ‘to blow’ and has been used by the meteorological community for almost 100 years. Back in 1925, a paper titled “Haboobs” was published in the Quarterly Journal of the Royal Meteorological Society.
