Sprites, dogs & devils

The outbreak of cold air following a cold front set the stage for today’s events. the Lake had:

  • Steam fog—a crowd of evanescent sprites that raced across the water surface.
  • Steam devils—whorl winds that towered over the fog (same link as steam fog).
  • Sun dogs—parhelia, a type of halo caused by sunlight and ice crystals.

This morning’s steam fog was as grand as one gets; the steam devil (below) was nice but not as grand as those of last December (but, then the season is still young). The sun dog was almost as nice as any I have seen around the Lake, especially as a portion of the parhelic circle extended from it to the left (see the discussion under haloes).

All in all, a lovely brisk morning for watching the Lake.
