Winter covering is a term used to describe the various forms of precipitation that occur during the winter season. RIME, HOAR, FROST, and SLEET are all types of winter covering. RIME is a type of white ice that forms when water droplets freeze onto surfaces. HOAR is a type of white FROST that forms on cold surfaces. FROST is a thin layer of ice crystals that form on cold surfaces. SLEET is a type of precipitation that is made up of small ice pellets. All of these forms of winter covering can be seen during the winter months.
