Was sind eigentlich leichter Frost, mäßiger Frost und strenger Frost?

Ice from the breath of Gail Davis forms around her face as she exercises by walking outside in Minneapolis, January 8, 2014.  A deadly blast of arctic air shattered decades-old temperature records as it enveloped the eastern United States on Tuesday, snarling air, road and rail travel, driving energy prices higher and overwhelming shelters for homeless people. According to AccuWeather.com, the extreme cold won't last much longer. The frigid air and "polar vortex" that affected about 240 million people in the United States and southern Canada will depart during the second half of this week, and a far-reaching January thaw will begin, according to AccuWeather.com.

Strenger Frost

Grundsätzlich spricht man von Frost, wenn die Lufttemperatur unter den Gefrierpunkt absinkt. Je nachdem, wie tief die Temperatur sinkt unterscheidet man verschiedene Frostarten:

Leichter Forst = 0 bis -4 Grad

mäßiger Frost = -4 bis -10 Grad

strenger/starker Frost = -10 bis -15 Grad

sehr strenger/sehr starker Frost = < -15 Grad.
