Understanding Freezing Rain
Freezing rain, a deceptively dangerous weather phenomenon, occurs when rain falls as liquid water but freezes upon contact with surfaces that are at or below freezing (0°C or 32°F). This creates a coating of ice, often referred to as glaze, which can accumulate rapidly and cause significant damage and disruption.
Okay, so we’ve got a freezing rain warning issued, meaning icy roads are a real possibility. To take your mind off the potential for hazardous driving, check out how Arkansas football totally crushed Texas Tech in the Liberty Bowl – Arkansas football tops Texas Tech in Liberty Bowl behind explosive – it was an awesome game! Anyway, back to the weather – stay safe out there and avoid unnecessary travel if the freezing rain hits.
Meteorological Conditions Leading to Freezing Rain Formation
Freezing rain forms under specific atmospheric conditions. A layer of warm, moist air aloft overlays a layer of cold air near the ground. Rain falls through the warm layer as liquid water. As it descends into the colder air near the surface, it doesn’t freeze immediately but instead remains supercooled – liquid water below its freezing point. Upon contact with a surface below freezing, the supercooled water instantly freezes, forming a layer of ice.
Differences Between Freezing Rain, Sleet, and Snow
Freezing rain, sleet, and snow are all forms of winter precipitation, but they differ significantly in their formation and appearance. Snow forms when water vapor in the atmosphere freezes directly into ice crystals. Sleet forms when rain falls through a layer of freezing air, freezing into small ice pellets before reaching the ground. Freezing rain, as described above, remains liquid until it contacts a freezing surface.
Step-by-Step Development of Freezing Rain
- Moisture rises and forms clouds in the atmosphere.
- A layer of warm air sits above a layer of cold air near the ground.
- Rain begins to fall from the warm layer.
- The rain remains liquid as it falls through the warm air, but becomes supercooled.
- Upon contact with surfaces at or below freezing, the supercooled rain instantly freezes.
- Ice accumulation builds up on surfaces, potentially causing significant hazards.
Impact of Freezing Rain on Various Surfaces
Freezing rain’s impact varies significantly depending on the surface it encounters. Roads become extremely slippery and dangerous, leading to accidents. Power lines can become coated with ice, causing them to break and leading to power outages. Trees and branches can become heavily laden with ice, resulting in breakage and potential damage to property. The weight of the ice can also cause structural damage to buildings.
