Ice lollies: An ice particle generated in supercooled conveyor belts

Abstract

Abstract On 21 January 2009, a maturing low‐pressure weather system approached the UK along with several associated frontal systems. As a part of the Aerosol Properties, PRocesses And InfluenceS on the Earth's climate‐Clouds project, an observational research flight took place in southern England, sampling the leading warm front of this system. During the flight, a distinctive hydrometeor type was repeatedly observed which has not been widely reported in previous studies. We refer to the hydrometeors as “drizzle‐rimed columnar ice” or “ice lollies” for short due to their characteristic shape. We discuss the processes that led to their formation using in situ and remote sensing data.
