haar

HAR
Cold sea fog blown onshore, especially along the coasts of northeast England and Scotland. An advection fog — formed when moist maritime air crosses cold coastal water. Can shut down a summer afternoon in minutes.
Etymology
Origin uncertain but well-documented — likely from Middle Dutch “hare” (biting cold wind) or Frisian “harig” (misty/damp), possibly related to Old Norse “hárr” (grey, hoary). Dictionaries generally hedge with “probably” rather than committing to one source.
