William Crookes started his remarkable scientific career as a weather observer. A brief description of his many achievements is followed by a more detailed account of the past, present and possible future of the radiometer he invented.
It is a well‐known fact that sometimes a halo display heralds an approaching cyclone, but could a halo display be an indicator of the presence of wildfire smoke and poor air quality? This article presents a few examples of unusual solar halos that formed over altocumulus clouds and were probably associated with the smoke created by wildfires burning in California. The article also discusses why superstitions...
Two typical cases of fog in Hong Kong are documented in this paper. The meteorological conditions leading to the occurrence of fog are examined using observations from ground‐based, remote sensing meteorological instruments. An acoustic sounding system and a microwave radiometer were used to monitor the atmospheric boundary layer and nowcast the low visibility weather conditions. The measurements...
A strong blocking anticyclone developed over Scandinavia through the last week of February and persisted into early March 2018, driving a bitter easterly wind from Siberia and bringing a severe cold outbreak and significant snowfall to the UK. A second spell of severe weather and low temperatures then returned to the UK over 17–19 March. The severe weather was preceded by a split in the stratospheric...
This article examines snow depths and low temperatures during the two snowy outbreaks of February and March 2018 in the United Kingdom and Ireland. In both nations, the cold spell was a very significant event. This report was compiled from information supplied by the Met Office and Met Éireann.

I have vivid recollections of fluffy powder‐snow, big drifts, and several days off school where we lived in Bracknell, Berkshire. We didn't even have the worst that this particular event threw at the UK: parts of East Anglia and Kent had continuous heavy snow, gale‐force winds, and...
