What’s the difference between glaze ice (from freezing rain) and black ice?

In winter forecasts you may hear two very similar-sounding terms. In Russian they’re «гололёд» and «гололедица» — and they describe different kinds of ice. Glaze ice (ice on objects) This is ice that coats objects: tree branches, power lines, roofs, railings, cars. It most often forms during freezing rain/drizzle when the air temperature is around 0 °C (or slightly below) and supercooled droplets freeze immediately on contact, creating a smooth, glassy layer.

Meteorological vs Astronomical Winter - What's the Difference?

While many associate the winter season with cold weather, snowy landscapes and the holiday season, there is more than one way to define the beginning and end of winter. Meteorologists and astronomers use two different systems to delineate the seasons - meteorological winter and astronomical winter. Let’s explore the key differences between these two definitions of winter.
