We have sunny Sunday skies right now. But it wasn't like that last night. High winds with cold, driving rains roared through San Diego all night long. In total we had hail, graupel and an inch of rain. The weatherman said Graupel... but what's graupel???
From the Wikipedia:
Graupel (also called soft hail or snow pellets; METAR code: GS)[1] refers to precipitation that forms when supercooled droplets of water condense on a snowflake, forming a 2–5 mm ball of rime; the snowflake acts as a nucleus of condensation in this process. The term graupel is the German word for this meteorological phenomenon.[2] Graupel is sometimes referred to as small hail, although the World Meteorological Organization defines small hail as snow pellets encapsulated by ice, a precipitation halfway between graupel and hail.[3
