Kirk here with a post about how it’s gotten colder recently. Last week (I think it was Wednesday when this article was published) the cold morning air caused a phenomenon in Amakusa called “kearashi” (気嵐; けあらし; smoke on the water [not the song, the phenomenon]).

— start quote — “It happens when the air mass is so cold it makes the water steam like a pot on a stove would,” Samuhel said. Sea smoke is also sometimes referred to as arctic sea smoke, frost smoke, steam fog or sea fog. — end quote —
