This year, at about four in the morning on November 27th, winter arrived with about as much drama as you can imagine. We had sudden head-cracking thunder and lightning, followed by mung-bean-sized pellets of compacted snow that hurtled down the chimney, pinged off the grate and rolled onto the bedroom floor.
The pellets, I’ve learned recently (here) are called “graupel”, and they occur when supercooled droplets of water condense on a snowflake. The idea of anything condensing on a snowflake seems odd, but there you have it, that’s graupel for you.
In the morning, the garden was covered in an inch of snow — both the conventional variety, and our new acquaintance, graupel. The next night we had two more inches of white stuff. It has been bone-chillingly cold for days, and there is no sign of the conditions out there changing back to the comparatively balmy maritime weather that we normally experience in this clement corner of Ireland.
Still, although I’m colder than I’ve been in months, I’m very pleased to have learned a new word, and to have had a chance to take some snowy pictures.
