Hoy 27 de julio de 2007, las regiones cercanas al Cerro de la Muerte amanecieron con pequeñas áreas nevadas. EN PLENO JULIO!!!. Apenas encuentre fotos, las subo

Como veran en el texto en ingles hay muchisimos tipos de Nieve. Incluso los Inuit no le tienen un solo nombre y son mas especificos con el tipo de precipitacion. Yo modestia aparte y en algunos casos desgraciadamente los conozcomo mejor dicho todos, viviendo en Canada y trabajando afuera quien no? Si el texto en Espaniol se viera ortodoxamente entonces tambien aqui casi nunca cae nieve. Solo flurries, Ice pellets (lo que cayo ayer en El Cerro del a Muerte), etc







Cristales de hielo en el Cerro de la Muerte

Una precipitación de pequeños cristales de hielo sorprendió ayer a quienes transitaban por la carretera Interamericana Sur, en el sector del cerro de la Muerte.

Aproximadamente a las 10 a. m., varios tramos de vegetación, entre los kilómetros 88 y 93 de esa ruta, quedaron cubiertos por una fina capa blanca de hielo que se mantuvo durante algunas horas.

Aunque no es frecuente, el fenómeno ya se ha presentado en ese sector, principalmente entre los meses de diciembre y febrero.

El 24 de enero del 2002 se produjo una precipitación similar en esa misma zona.

No es nieve. Berny Fallas, especialista del Instituto Meteorológico Nacional (IMN), aclaró que estas precipitaciones no se pueden describir como nieve.

“La nieve tiene una consistencia de copos muy frágiles. Lo de ayer fueron cristales pequeños de hielo, que tienen una forma diferente y su consistencia es más fuerte que la de los copos”, explicó.

Estos fenómenos se producen cuando se conjugan condiciones ambientales con el descenso en la temperatura de las nubes a menos de 0 grados centígrados y también cambios en la forma de estas.


La precipitación de ayer se originó por el descenso en la temperatura interior de una nube, “que también presentó un crecimiento vertical considerable sobre ese sector específico del cerro de la Muerte”, explicó el meteorólogo.









Types of snow

Hoar frost that grows on the snow surface due to water vapor moving up through the snow on cold, clear nights
[edit] Snow falling
Blizzard
A long-lasting snow storm with intense snowfall and usually high winds. Particularly severe storms can create whiteout conditions where visibility is reduced to less than 1 m.
Flurry
A period of light snow with usually little accumulation with occasional moderate snowfall.
Freezing rain
Rain that freezes on impact with a sufficiently cold surface. This can cover trees in a uniform layer of very clear, shiny ice – a beautiful phenomenon, though excessive accumulation can break tree limbs and utility lines, causing utility failures and possible property damage.

Snowbird ski resort, one of the snowiest places in the U.S.Graupel
Precipitation formed when freezing fog condenses on a snowflake, forming a ball of rime ice. Also known as snow pellets.
Ground blizzard
Occurs when a strong wind drives already fallen snow to create drifts and whiteouts.
Hail
Many-layered ice balls, ranging from "pea" sized (0.25 in, 6 mm) to "golf ball" sized (1.75 in, 43 mm), to, in rare cases, "softball" sized or greater (*>4.25 in, 108 mm).
Hailstorm
A storm of hail. If the hail is sufficiently large, it can cause damage to cars or even people.
Lake effect snow
Produced when cold winds move across long expanses of warmer lake water, picking up water vapor which freezes and is deposited on the lake's shores.
Pukak
A layer at the bottom of old snowpack, consisting of coarse, sugar-like ice crystals and air. Subnivean animals live in the pukak layer because its temperature is generally stable at a few degrees below freezing and it can be tunneled through with relative ease.
Sleet
In Britain, rain mixed with snow; in America, ice pellets formed when snowflakes pass through a layer of warm air, partially thaw, then refreeze on further descent.
Snow pellets
See graupel.
Snow squall
A brief, very intense snowstorm.
Snow storm
A long storm of relatively heavy snow.
Soft hail
Granules of snow or ice pellets formed when supercooled water accretes on ice crystals or snowflakes.
Thundersnow
A thunderstorm which produces snow as the primary form of precipitation.

[edit] Snow on the ground

Snow covering a leaf.
Winter in CroatiaArtificial snow
Snow can be also manufactured using snow cannons, which actually create tiny granules more like soft hail (this is sometimes called "grits" by those in the southern U.S. for its likeness to the texture of the food). In recent years, snow cannons have been produced that create more natural-looking snow, but these machines are prohibitively expensive.
Blowing snow
Snow on ground that is being moved around by wind. See ground blizzard.
Corn
Coarse, granular wet snow. Most commonly used by skiers describing good spring snow. Corn is the result of diurnal cycle of melting and refreezing.
Crust
A double layer of snow in which the lower layer may be powdery dry but where the surface is frozen together into a stiff, icy surface, which often can support human weight.
Ice
Densely packed material formed from snow that doesn't contain air bubbles. Depending on the snow accumulation rate, the air temperature, and the weight of the snow in the upper layers, it can take snow a few hours or a few decades to form into ice.
Firn
Snow which has been lying for at least a year but which has not yet consolidated into glacier ice. It is granular.
Packed Powder
The most common snow cover on ski slopes, consisting of powder snow that has lain on the ground long enough to become compressed, but is still loose.

Heavy snow on pine treePacking snow
Snow that is at or near the melting point, so that it can easily be packed into snowballs and hurled at other people or objects. This is perfect for snow fights and other winter fun, such as making a snowman, or a snow fort.
Penitentes
Tall blades of snow found at high altitudes.
Powder
Freshly fallen, uncompacted snow. The density and moisture content of powder snow can vary widely; snowfall in coastal regions and areas with higher humidity is usually heavier than a similar depth of snowfall in an arid or continental region. Light, dry (low moisture content) powder snow is prized by skiers and snowboarders. It is often found in the Rocky Mountains of North America and in Niseko, Japan.
Slush
Snow which partially melts upon reaching the ground, to the point that it accumulates in puddles of partially-frozen water.

The textures of a snowdrift on the Long Mynd, ShropshireSnowdrift
Large piles of snow which occur near walls and curbs, as the wind tends to push the snow up toward the vertical surfaces.
Watermelon snow
A reddish/pink colored snow that smells like watermelons, and is

Muy interesante e instructiva información Kuquito. Todo un acontecimiento en el país, pues si bien es cierto la temperatura ha descendido en Costa Rica (Cerro Chirripó) hasta -13 °C bajo cero, la nieve no logra mantenerse demasiado tiempo debido a nuestra latitud geográfica. Gracias por los datos.

Si, gracias, Kuquito por la info. Yo viví en Minnesota, y ese tipo de "flurries" o "sleet" uno lo llamaba "snow" en general porque caía, yo lo sigo llamando "snowfall" porque usted no diría "sleetfall" o "flurryfall"
