To injure by frost; to freeze, as plants.
To cover with hoarfrost; to produce a surface resembling frost upon, as upon cake, metals, or glass; as, glass may be frosted by exposure to hydrofluoric acid.
Deposition of ice at the Earth's surface because of atmospheric cooling.
the formation of ice crystals in the forms of scales, needles, feathers, or fans, which develop under conditions similar to dew, except that the minimum temperature has dropped to at least 32 F degrees. (The 32 F sometimes is only at the plant level, while shelter temperatures (higher up) reporting 35 F, for example.)
Ice crystal deposits formed by sublimation (conversion of water vapor directly to ice) when temperature and dew point are below freezing.
Water that freezes a ground level when the air temperatures falls below 0oC.
It is important for gardeners in cooler climates to be familiar with the dates of first and last frost in their area. Because many plants evolved in tropical or sub-tropical climates, they are not tolerant of cold temperatures, and permanent damage is caused when the water held in plant cells freezes and expands, severing cell walls. Protect against frost by using row covers, cold frames, or other devices that trap warm air around plants. Remember also that cold clear nights are more dangerous than cold humid nights because water condensing from cold air can give off enough heat to moderate damage of plant tissue.
ice crystals forming a white deposit (especially on objects outside)
weather cold enough to cause freezing
the formation of frost or ice on a surface
decorate with frosting; "frost a cake"
cover with frost; "ice crystals frosted the glass"
deposit of ice crystals that occurs when the air temperature is at or below the freezing point of water. Also used to describe the icy deposits of water vapor that form on such surfaces as windows and windshields, which are colder than the surrounding air and which have a temperature below freezing.
occurs when a minority constituent condenses out from an atmosphere, such as water on freezing out of the Earth's atmosphere or (probably) methane on Pluto. For both Earth and Pluto the main constituent is molecular nitrogen (N 2). When the atmosphere itself condenses, as in N 2 on Pluto, it forms ice, not frost. The difference is significant, both from the surface (very different surface textures result from the two processes) and from the atmosphere, where frost formation is limited by the ability of the minority species to move through the majority component, while condensation of ice is only limited by the ability of the atmosphere to cool.
Ice crystals which form on surfaces due to the cooling of an air mass to its frost point. If the temperature of the air mass were above 32 degrees F, dew would form instead of frost.
Occurs when the temperature drops below 32 degrees Fahrenheit.
the formation of thin ice crystals on the ground or other surfaces; frost develops under conditions similar to those of dew, except in temperature of the earth's surface and earthbound objects fall below thirty-two degrees Fahrenheit.
Crystals of frozen vapor.
Small ice crystals which form when water condenses into droplets onto objects near the ground at temperatures below freezing.
pararibes the formation of thin ice crystals on the ground or other surfaces. Frost develops when the temperature of the earth's surface falls below 32 degrees Fahrenheit, but because frost is primarily an event that occurs as the result of radiational cooling, it frequently occurs with air temperatures in the middle 30s.
1. To coat a cake with an icing of confectioners sugar. 2. To dip the rim of a glass in egg white and caster sugar and then chill in a refrigerator until set.
A covering of ice on exposed surfaces when the air temperature falls below the frost point.
The ice crystals that form on cold surfaces as a result of deposition of moisture in the air on objects that are below the freezing point.
A covering of small ice crystals that forms on or near the ground when temperatures approach or drop below 32.
the ice that forms on surfaces as a result of the temperature of that surface reaching freezing before the air becomes saturated with water gallon - a unit of measure equal to four quarts or 128 fluid ounces
ice that sublimates onto a surface
formation of thin ice crystals on the ground or other surfaces in the form of scales, needles, feathers, or fans. Frost develops under conditions similar to dew, except the temperatures of the Earth's surface and earthbound objects falls below 32°F. As with the term 'freeze', this condition is primarily significant during the growing season. If a frost period is sufficiently severe to end the growing season or delay its beginning, it is commonly referred to as a 'killing frost'. Because frost is primarily an event that occurs as the result of radiational cooling, it frequently occurs with a thermometer level temperature in the mid-30s.
the condition which exists ice is formed on the earth's surface when the temperature falls below freezing
Ice crystals that form on grass and other objects when the temperature and dew point fall below freezing.
Ice crystals formed on grass or other objects by the sublimation of water vapor from the air.
The covering of ice that is formed on exposed surfaces whose temperature falls below freezing.
Water vapour which deposits directly as a solid on a surface colder than the surrounding air and which has a temperature below freezing. It is not frozen dew. Killing Frost is a frost severe enough to end the growing season.
The condensation and freezing of moisture in the air. Tender plants will suffer extensive damage or die when exposed to frost.
1. The fuzzy layer of ice crystals on a cold object, such as a window or bridge, that forms by direct deposition of water vapor to solid ice. 2. The condition that exists when the temperature of the earth's surface and earthbound objects fall below freezing. Depending upon the actual values of ambient-air temperature, dewpoint, and the temperature attained by surface objects, frost may occur in a variety of forms. These include a general freeze, hoarfrost (or white frost), and dry freeze (or black frost). If a frost period is sufficiently severe to end the growing season (or delay its beginning), it is commonly referred to as a killing frost. See frost day, ground frost See frozen ground. 4. Same as hoarfrost. Compare rime.
To apply sugar, frosting, glaze, or icing to fruit, cake, or other food.
the condition which exists when the temperature near the earth's surface and earth-bound objects falls below freezing (0 degrees Celsius or 32 degrees Fahrenheit).
The covering of ice crystals that forms by direct sublimation on exposed surfaces whose temperature is below freezing.
1. A covering of minute ice crystals that form on a cold surface. 2. Frozen soil.
Frost is a solid deposition of water vapor from saturated air.
