The frost line —also known as frost depth or freezing depth —is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt ...
The spokesperson added that the agency has "only received three historic requests for extreme heat declarations" — two in 1980 and one in 1995 — and that they were all "denied because they did ...
Leidenfrost effect. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly. Because of this repulsive force, a droplet hovers over the surface, rather ...
Specific criteria vary among local Weather Forecast Offices, due to climate variability and the effect of excessive heat on the local population. Typical HI values are maximum daytime temperatures above 105 to 110 °F (41 to 43 °C) for up to three hours per day, with minimum nighttime temperatures above 75 °F (24 °C) (criteria may vary ...
