Sleet and freezing rain occur by a similar process, but are different forms of precipitation. Both are most common in the winter. Sleet occurs when snowflakes melt into a raindrop in a wedge of ...
Cold injury (or cold weather injury) is damage to the body from cold exposure, including hypothermia and several skin injuries. [6] Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. [5] Freezing cold injuries involve tissue damage when exposed to temperatures below freezing (less than 0 degrees Celsius).
An early (2018) warming stripes graphic published by their originator, climatologist Ed Hawkins. [1] The progression from blue (cooler) to red (warmer) stripes portrays annual increases of global average temperature since 1850 (left side of graphic) until the date of the graphic (right side).
On March 4, 2014, the United States House of Representatives passed the Home Heating Emergency Assistance Through Transportation Act of 2014 (H.R. 4076; 113th Congress) in reaction to the extreme cold weather. [81] The bill, if it becomes law, would create an emergency exception to existing Federal Motor Carrier Safety Administration ...
Such freezing may be promoted by effects such as flood frost or frost pocket. [5] These occur when ground-level radiation cools air until it flows downhill and accumulates in pockets of very cold air in valleys and hollows. Hoar frost may freeze in such low-lying cold air even when the air temperature a few feet above ground is well above freezing.
Freezing rain often causes major power outages by forming glaze ice. When the freezing rain or drizzle is light and not prolonged, the ice formed is thin and usually causes only minor damage (relieving trees of their dead branches, etc.). [10] When large quantities accumulate, however, it is one of the most dangerous types of winter hazard. [11]
An ice storm, also known as a glaze event or a silver storm, is a type of winter storm characterized by freezing rain. [1] The U.S. National Weather Service defines an ice storm as a storm which results in the accumulation of at least 0.25-inch (6.4 mm) of ice on exposed surfaces.
