Phenology

1/2&3/21: We started the new year with a really neat meteorological event known as "rime ice." This is different from hoar-frost in that for rime ice forms as fog settles over the landscape when the temps are below freezing- super cooled water droplets (water that is below freezing but still liquid) in the fog attach to any object it hits and forms a beautiful furry or spikey ice on the object. Hoar frost is formed when water vapor in the air goes straight from vapor to a solid on objects, skipping the liquid phase- this occurs on clean nights with a light wind. We had fog warnings both nights, creating rime ice vs hoar-frost.
