[h=2]Why Did Philadelphia Get More Snow Sunday Than Last Winter?
[h=5]December 09, 2013; 9:29 PM
Share |
Philadelphia International Airport received more snow (8.6 inches) from a single storm this past Sunday than it did all of last winter, when 8.3 inches fell.
Mother nature pulled out all the stops with heavy snow in a narrow zone centered near the Mason-Dixon Line Sunday.
The heavy snow quickly covered roadways, caused flight delays and cancellations, and contributed to many accidents.
The mechanics and variables behind the snow debacle are complex and numerous. A simple explanation is offered in this story.
According to Brian Wimer, AccuWeather winter weather expert, "For starters, a layer of fresh cold air moved in near the surface Saturday night over the mid-Atlantic and shortly thereafter a weak storm moved northeastward into that fresh cold air."
While the storm was weak, there was plenty of warm, moist air to the south waiting to be tapped.
"The weak storm allowed a warm front to set up several thousand feet above the ground which caused the air to rapidly rise and cool in an unusually narrow zone rather than be spread out over hundreds of square miles," Wimer said.
The band of heavy snow focused from parts of West Virginia to northern Virginia, northern Maryland, southern Pennsylvania, northern Delaware and southern New Jersey, including the Wilmington, Del., and Philadelphia metro areas. At times, the snow fell at the rate of 1 to 3 inches per hour.
As a result, many areas exceeded their original prediction of snow in a little over an hour. The liquid amount from the snow around Philadelphia was a factor of 20 lower, so that 1 inch of snow was only about 0.05 of an inch of water or rain.

The band of snow could have just as easily set up farther south or north compared to where it did. Instead, it occurred in the vicinity of the Mason-Dixon Line.
According to AccuWeather.com Expert Senior Meteorologist Henry Margusity, "Horizontal winds were very light from around 5,000 to 10,000 feet up, near where the snowflakes were rapidly forming and growing most vigorously."
These light winds allowed the snowflakes to become very large and not be blown apart.
There are probably a couple of dozen of potential events similar to this past Sunday but in reality they only occur a handful of times over nation during a typical winter. Figuring out exactly where they will first set up and expand to prior to their occurrence is very challenging.
[h=4]Snowfall From the Sunday to Monday Storm (As of Midday Monday)
Another storm will affect part of the Northeast Tuesday. For many areas along the I-95 corridor, there may be enough to shovel and plow.
Most areas will receive between 1 and 3 inches of snow from the new storm Tuesday, spread out over a six- to eight-hour period. A narrow swath of 3 to 6 inches of snow will fall, including in some of the major I-95 cities.

حالا جدا از شوخی یه بخشی از پایان نامم مربوط بود به همین بحث تصادفات تو شرایط حاد آب و هوایی، موضوع جالبیه

سلام محمد رضا جان
منتظرم تا نقشه های EUMETRAIN برای ساعت 06:00 بشن بعد اونوقت بهتر میشه در موردش اظهار نظر کرد.
در ارتباط با تصادف در شرایط حاد اب و هوایی ، خدا قسمت هیچ کس نکنه!!
راستی در مورد ریختن گازوئیل بر سطح اتوبان تحقیق نکردید؟
من یک بار در اتوبان مشهد قوچان در حال رانندگی بود و خدا رو شکر بر عکس همیشه سرعتم خیلی کم بود و از دور متوجه خطر شدم.
نزدیک مشهد یک پمپ بنزینی هست که باند شمالی جاده است و زیر گذر داره! یک کامیون 10 چرخ رفته بود سوخت گیری کرده بود ، حالا نمیدونم باکش نشتی داشت یا مشکل دیگه ای بود که گازوئیل با حجم خیلی زیاد بر سطح جاده در امتداد مسیر حرکت کامیون بر روی زمین ریخته بود و ماشینهای پشت سر همه بصورت زنجیر وار تصادفات وحشتناکی کرده بودند که من از تلفاتش اطلاعات چندانی ندارم!
حالا اینجا این سوال مطرح میشه که قانون در مورد اون کامیون چه تصمیمی میگیره و کسانیکه در اثر این سهل انگاری دچار تلفات و یا خسارات جبران ناپذیر میشن چه حکمی میده!
بعد از صحنه تصادف که من از اونجا گذر کردم دیدم چند تا ماشین دنبال اون کامیون افتاده بودند، متوقفش کردند و به قصد کشت داشتند بنده خدا رو میزدند!!!!!!!!!!!!!!!!!
