نه محمد از تهران تلفني با من صحبت كرد گفت تو فروم عكس ابر زلزله بلده مازندران رو بزار
ابر زلزله 83 بلده مازندران به بزرگي 6.3 ريشتر:
تشکر . الان فاصله هوایی بلده تا تهران و دیدم تا شمال شهر 50 و تا خونه ما 70 کیلومتر فاصله داره . این نقطه ای که ابره دیده شده احتمالا همون سمت غرب مازندران هست که فاصلش با تهران بیشتره یه 20 کیلومتری نسبت به بلده . بعیده این ابر بالای 5 ریشتر باشه نه ؟ امیدوارم اصلن زلزله ای نباشه چه تهران چه شمال

هنوز من در مورد ماهيت ابرنظر قطعي ندارم. اما اگه بخوايم نگران باشيم با توجه به نقطه شروع ابر مذكور بايد در جايي در غرب استان مازندران نگران بود.

وقتي از منطقه بلده فوران مي كنه به دليل گرما ميعان لازم صورت نميگيره در نتيجه از بدو ايجاد توي تصاوير رويت نمي شه تا اينكه وقتي به ارتفاع معيني ميرسه و توسط بايد به شرق حركت مي كنه به دليل سرمايش نسبي ارتفاع مورد نظر تراكم لازم در توده بخار صورت مي گيره و در حوالي اونجا به يكباره توي تصاوير نمايان مي شه. نكته ديگه 2 تكه بودن ابر به گفته شيميست چيني اثر كوهستان هاي منطقه بوده كه باعث شده بخارات در 2 راستا فوران كنن.

[h=2]DC, Virginia, Maryland Midweek Snowstorm
[h=6]By Alex Sosnowski, Expert Senior Meteorologist [h=5]March 03, 2013; 2:50 PM
Share |
AccuWeather.com will issue specific snowfall accumulation maps when the storm is approximately within 48 hours of hitting a particular area. This graphic above shows expected mid-Atlantic impacts and the area most likely to receive heavy snow.
Impacts from a storm targeting millions of people in the eastern states will range from travel disruptions caused by heavy snow to power outages produced by strong winds to flooding from storm surge.
A major storm will bring heavy snow from parts of North Carolina to portions of West Virginia, Pennsylvania and New Jersey spanning Wednesday into Thursday.
The storm will be moving through the central Appalachians toward the mid-Atlantic coast during the middle of the week, after blasting portions of the Plains and Midwest Monday into Tuesday.
Snow
Based on the latest information, the area that is most likely to receive a foot or more of snow lies from northwestern North Carolina through northern and western Virginia, the mountains of West Virginia and western and part of central Maryland.
Charlottesville, Roanoke, Harrisonburg and Winchester, Va.; Frederick and Hagerstown, Md. and Martinsburg, W.Va. appear to be in the middle of the zone with the greatest snow potential. This potential would be immobilizing snow. The weight of heavy, weight snow can bring down trees and power lines in this area.
However, dozens of other cities in the region could receive anywhere from a couple of inches of slush to a foot or more of back-breaking snow. These include Washington, D.C., Baltimore, Md., Richmond, Va., Dover, Del. and Vineland, N.J. These areas are likely to receive rain during part of the storm and a larger percentage of the snow that falls is more likely to melt for a time.
As the rate of snow becomes heavy, roads can quickly become clogged with snow, potentially stranding motorists. Deicing time will increase at area airports in the path of the storm. Potential flight delays and cancellations from heavy snow will hit Minneapolis and Chicago first, then will spread to multiple airports in the I-95 mid-Atlantic with the possibility of delayed aircraft and crews elsewhere across the nation.
This map shows the probability of areas most likely to receive six inches or more of snow during Tuesday in the Midwest and Wednesday in the East.
There is still the risk the storm strengthens upon nearing the coast and either turns farther to the north or grows in size spreading snow and other effects farther north.
Philadelphia, Pittsburgh and Harrisburg are also on the bubble with the chance of a period of heavier snow that can bring a big accumulation or lesser snow to primarily a rain/snow mix. These details will not be known until the storm is virtually under way. A shift in track of the storm and its heavy snow by 50 miles can make the difference.

Cold Heads South for Spring Break
New York City is likely to be on the northernmost edge of the lesser snow area. Unless the storm stalls and expands substantially northward, a heavy snowfall appears to be a low probability. Cape Cod and Long Island, which extend out into the Atlantic a bit more, have a slightly higher chance of a period of accumulating snow.
A slightly more southerly track would throw heavier snow farther south over western and central North Carolina. As a result folks in Charlotte, Winston-Salem and Raleigh, N.C. and Norfolk, Va. should watch this storm closely.
Wind, Coastal Flooding and Beach Erosion
Based on the latest information, AccuWeather.com meteorologists feel this storm will deliver the punch of a moderate to strong nor'easter. Such storms produce winds over a large fetch of water and drive that water toward the coast. The shape of the coast and wind direction determines which areas are most susceptible to coastal flooding. The duration and strength of the onshore wind determines the severity of the water rise.
Winds can become strong enough to cause sporadic power outages from eastern North Carolina to southern New Jersey. Gusts to 60 mph are possible. A 24 to 48 hour period of pounding surf will cause moderate beach erosion in these areas. Offshore seas can reach 30 feet.
Areas from eastern North Carolina to southern New Jersey are most likely to have coastal flooding problems during times of high tide Wednesday into Thursday. While it is a bit too early to be highly confident on water level rises, there is a chance of tides levels running between 2 to 4 feet above published values. Fortunately, astronomical impact around the time of the storm be minimal with significant distance between the new and full moon phases.
Because of the track and speed as to which the storm will strengthen, the risk of coastal flooding problems over portions of the Chesapeake and Delaware Bays cannot be eliminated at this time. There may be a period where winds are from a direction to cause water to back up.
AccuWeather.com will continue to keep you updated on this storm until it heads out to sea Friday through videos, blogs, weather news stories and informative graphics. This story was published at 12:15 p.m. EST, Sun., Mar 3, 2013 and will be updated periodically.

[h=2]Storm This Week Versus '62 Ash Wednesday Storm
[h=6]By Alex Sosnowski, Expert Senior Meteorologist [h=5]March 03, 2013; 3:08 PM
Weather Expert Evan Myers and Chief Meteorologist Elliot Abrams discuss the current cold and the impending storm next week.
This surface and upper atmosphere weather map from March 6, 1962 appears from the archives of the U.S. Department of Commerce. We apologize for the faded appearance. Note the Omega Block setup with the jet stream in the lower left panel.

No two storms are ever exactly alike, and the case with the storm on the East Coast in March 6-7, 2013, will be no exception to this rule. However, there may be similarities to other storms over the past and particularly one that occurred in 1962 on the same date.
The Ash Wednesday Storm, as it was called, caused everything from feet of snow to high winds and extensive coastal flooding.
The storm which formed on February 5, 1962, stalled along the mid-Atlantic coast and blasted areas with heavy precipitation, gales and storm surge for days. Over 40 people were killed, over 1,000 others were injured and damage reached $200 million 1962 dollars.
Chief Meteorologist Elliot Abrams and the majority of AccuWeather.com meteorologists concur that the storm of 1962 and the storm during the middle of this week bear similarities on the historical weather maps.
The storm of 1962 caused extensive damage to boardwalks and beaches and flooding in communities from North Carolina to Long Island with beach erosion as far north as Maine.
According to the National Oceanic and Atmospheric Administration (NOAA), during the Ash Wednesday Storm of 1962, part of Steel Pier at Atlantic City, N.J., was destroyed and NASA's Wallops Island facility sustained extensive damage. Chincoteague and Assateague islands were completely submerged. Winds reached 70 mph and offshore seas approached 40 feet. Two feet of snow fell from Charlottesville to Winchester, Va., with 18 inches of snow falling as far north as the middle of Pennsylvania. Snow fell as far south as Alabama.
The keys to the storm for during the middle of this week in terms of impact are how strong it becomes, how long it lingers along the mid-Atlantic coast and so being how far north it turns.

Odds are against a storm lingering for three or four days like the '62 Ash Wednesday Storm, so damage and flooding are likely to be far less severe.
However, next week's storm could slow down, as the storm strengthens near the coast. If it does this, there could be problems on the coast in terms of strong wind and coastal flooding.
Based on new information, the setup should provide the storm with enough forward momentum, legs if you will, so that the period of strong winds and rough surf conditions are limited to several hours. As a result we are not likely to push a great deal of water toward the coast, when compared to the '62 storm.
In addition, less impact is likely with the storm this week in areas hit hardest by Sandy from northern New Jersey to Long Island. The latest indications are that this storm will be centered farther south.
"The storm in '62 hit at a time of high astronomical tides; There was a new moon on March 6, 1962," according to Elliot Abrams, "Fortunately, the storm next week will be occurring multiple days well away from the new and full moon."
Abrams is not dismissing the potential for coastal flooding, due to onshore flow for a day or two, but suggesting that at least it would not be made worse by the phase of the moon.
The greatest impact from water-level rise would occur around the high tide cycles each day.
The storm is likely to produce a swath of heavy snow from the mountains of West Virginia, Virginia, North Carolina and Maryland to part of the mid-Atlantic Coast. It gets tricky near the coast, due to warm air issues bringing rain instead of snow or at least rain during part of the storm.
The storm next week is scheduled to occur about a week ahead of the 20th anniversary of the "Storm of the Century," otherwise known as the "Blizzard of '93."
That mid-March storm developed over the Gulf of Mexico and turned northeastward riding up the Appalachians and Atlantic Seaboard with great damage and coastal flooding, high winds and feet of snow and did so at most locations for a mere 24 hours.
While completely different storms in terms of track and/or origination, the storm next week has the potential to deliver disruptive consequences for a heavily populated part of the nation, just as the Ash Wednesday Storm of 1962 and the Blizzard of 1993.
The storm of 1962 and 1993 were meteorological monsters and the storm next week has the potential to be the same from the impact of heavy snow alone. There is the potential for this storm to deliver one to two feet of snow at its most intense phase with just the right atmospheric conditions.
Moderate to strong nor'easter storm conditions from eastern New Carolina to southeastern Virginia, the Delmarva Peninsula and the southern part of New Jersey.
