Ja, de Arctic heeft cyclonen of orkanen of typhonen, of hoe je ze maar noemen wilt dat zijn namelijk allemaal verschillende namen voor hetzelfde fenomeen. De naam is afhankelijk van de regio waarin de cycloon/orkaan/typhoon zit. Cycloon: Indische oceaan, Orkaan: Atlantische oceaan: Typhoon: Grote oceaan. In de Arctic heten ze cyclonen of orkanen naar gelang wie je spreekt.quote:Op dinsdag 7 januari 2014 16:51 schreef Frutsel het volgende:

Cycloon? Aparte naam voor iets rond de noordpool. Ik dacht dat ze die namen alleen voor de "warmere stormen"... (Tropische Cycloon?) Nooit geweten dat die krengen daar ook cyclonen worden genoemd?

Orkanen, cyclonen, tyfonen is volgens mij weggelegd voor het tropische gedeelte. Daarbuiten spreekt men over depressies, stormdepressies etc.
Maar idd een depressie kan ook zeer verwoestend en in omvang zeer groot zijn. Ooit ergens gelezen dat de zwaarste valwinden op de zuidpool voorkomen. (koude lucht die van hoger gelegen gebieden naar beneden dondert.)
Ik heb hier wel vaker discussies over gehad. Ik vind zelf n.l. ook lagedrukgebieden met orkaankracht gewoon orkanen, maar volgens de "geleerden" mag je die naam alleen geven aan de systemen die in de tropen voor komen.quote:Op dinsdag 7 januari 2014 22:36 schreef cynicus het volgende:

De koude valwind in Antarctica heet katabatische wind en die heb je ook op andere grote schuine vlakken in de wereld.

Niks van aantrekken dus, die 'geleerden'quote:Polar lows are small, intense cyclones that form over open ocean during the cold season. From satellite imagery, polar lows can look much like a hurricane, with a large spiral of clouds centered around an eyefor this reason they are sometimes called Arctic hurricanes.
quote:ATLANTA (AP) Fountains froze over, a 200-foot Ferris wheel in Atlanta shut down, and Southerners had to dig out winter coats, hats and gloves they almost never have to use.
The brutal polar air that has made the Midwest shiver over the past few days spread to the East and the Deep South on Tuesday, shattering records that in some cases had stood for more than a century.
The mercury plunged into the single digits and teens from Boston and New York to Atlanta, Birmingham, Nashville and Little Rock places where many people dont know the first thing about extreme cold.
I didnt think the South got this cold, said Marty Williams, a homeless man, originally from Chicago, who took shelter at a church in Atlanta, where it hit a record low of 6 degrees. That was the main reason for me to come down from up North, from the cold, to get away from all that stuff.
The morning weather map for the eastern half of the U.S. looked like an algebra worksheet: lots of small, negative numbers. In fact, the Midwest and the East were colder than much of Antarctica.
The cold turned deadly for some: Authorities reported at least 21 cold-related deaths across the country since Sunday, including seven in Illinois, and six in Indiana. At least five people died after collapsing while shoveling snow, while several victims were identified as homeless people who either refused shelter or didnt make it to a warm haven soon enough to save themselves from the bitter temperatures.
In Missouri on Monday, a 1-year-old boy was killed when the car he was riding in struck a snow plow, and a 20-year-old woman was killed in a separate crash after her car slid on ice and into the path of a tractor-trailer.
In a phenomenon that forecasters said is actually not all that unusual, all 50 states saw freezing temperatures at some point Tuesday. That included Hawaii, where it was 18 degrees atop Mauna Kea, a dormant volcano.
The big chill started in the Midwest over the weekend, caused by a kink in the polar vortex, the strong winds that circulate around the North Pole. By Tuesday, the icy air covered about half the country, and records were shattered like icicles up and down the Eastern Seaboard.
It was 1 degree in Reading, Pa., and 2 in Trenton, N.J. New York City plummeted to 4 degrees; the old record for the date was 6, set in 1896.
Its brutal out here, said Spunkiy Jon, who took a break from her sanitation job in New York to smoke a cigarette in the cab of a garbage truck. Your fingers freeze off after three minutes, your cheeks feel as if youre going to get windburn, and you work as quick as you can.
Farther south, Birmingham, Ala., dipped to a low of 7, four degrees colder than the old mark, set in 1970. Huntsville, Ala., dropped to 5, Nashville, Tenn., got down to 2, and Little Rock, Ark., fell to 9. Charlotte, N.C., reached 6 degrees, breaking the 12-degree record that had stood since 1884.
The deep freeze dragged on in the Midwest as well, with the thermometer reaching minus 12 overnight in the Chicago area and 14 below in suburban St. Louis. More than 500 Amtrak passengers were stranded overnight on three Chicago-bound trains that were stopped by blowing and drifting snow in Illinois. Food ran low, but the heat stayed on.
The worst should be over in the next day or two, when the polar vortex is expected to straighten itself out. Warmer weather that is, near or above freezing is in the forecast for much of the stricken part of the country.
On Tuesday, many schools and day care centers across the eastern half of the U.S. were closed so that youngsters wouldnt be exposed to the dangerous cold. Officials opened shelters for the homeless and anyone else who needed a warm place.
With the bitter cold slowing baggage handling and aircraft refueling, airlines canceled more than 2,000 flights in the U.S., bringing the four-day total to more than 11,000.
In New Orleans, which reported a low of 26 degrees, hardware stores ran out of pipe insulation. A pipe burst in an Atlanta suburb and a main road quickly froze over. In downtown Atlanta, a Ferris wheel near Centennial Olympic Park that opened over the summer to give riders a birds eye view of the city closed because it was too cold.
Farther south in Pensacola, Fla., a Gulf Coast city better known for its white sand beaches than frost, streets normally filled with joggers, bikers and people walking dogs were deserted early Tuesday. A sign on a bank flashed 19 degrees. Patches of ice sparkled in parking lots where puddles froze overnight.Continued...
quote:Texas cold in Perspective
In the summer in Arizona, when people complain about the heat, the standard response is, “But it’s a dry heat.” Here in Texas, with this cold snap, remember: it’s a warm cold.
Waarschijnlijk omdat ze het daar gewend zijn dergelijke kou.quote:Op woensdag 8 januari 2014 14:12 schreef xzaz het volgende:

The cold weather is still impacting air travel, mainly because of a backlog caused by hundreds of flight cancellationson Tuesday. Early Wednesday morning, the airportreported the cancellations of more than 230 flights due to arrive and 165 flights that had been scheduled to depart.
More than 600 flights were cancelled during a "ground stop" Tuesday morning, when the temperature felt like -40 C with wind chill. Although the airport is now "fully open and operational," an airport official says, due to the backlog, airlines have been encouraged to reduce operations until they catch up.
