محسن جان خیلی فرق داره اینکه با ماشین با بخاری روشن برین وسط شهر توی برف یه دور بزنین و برگردین با اینکه پیاده توی دمای 4- حدود یک ساعت و نیم راه برین و عکس بگیرین. یه خرده قیاس‌مع‌الفارقه.
البته شایدم تصور کنین که من اغراق کردم (همون چاخان کردن خودمون!)، که این یه بحث دیگه‌ست و جاش اینجا نیست!!!!

وای ماهان جان
شما چقدر حساس هستید!!!!!
حالا این چیزی که من واسه مقایسه گذشتم ربطش رو به بخاری و ماشینو این حرفها رو نمیدونم!!!!!!
من خودم شخصا از آلمان یک تصور دیگه ای داشتم از لحاظ سرما!!!
نمیخواستم مقایسه کنم ولی من چند سال به اجبار به قوچان رفت و آمد داشتم و واقعا معنی سرما بیشتر از 20- زیر درجه رو و اونها با پای پیاده خوب میدونم چیه!
بعد هم بخش عمده کاری که من در سالیان گذشته انجام میدادم صرفا انجام عملیات میدانی بوده و مجبور بودم تو گرما و سرما و یا روز تا شب( گاهی شبکاری تا صبح) زیر آسمون خدا
کار کنم ، حالا نگاه نکن که الان بر اساس درخواست خودم و موافقت شرکت کمتر بیرون میرم ولی یک عمری محکوم و مجبور به تحمل گرما و یا سرماهای بسیار شدید بودم.
بعد هم شهریکه شما توش زندگی می کنی خیلی زیباست و همه چیزش اوکیه ولی از لحاظ زمستون تا حالا که مقایسه کردم مثل زمستون های مشهد تقریبا سرد و خشکه و کیفیت بارشش هم دقیقا عین اینجا میمونه و برف های خشک و ریز میباره!
بهرحال ما از شما توقع نداریم اینقدر زود ناراحت و دلگیر بشید چون حالا من چیزی بدی نگفتم به خدا!
یک چیز رو هم یادم رفت بگم :
از نظر من عکاسی یک عشقه و هر عشقی هم یک بهایی داره که من حاضرم با تموم وجودم این بهاء رو بپرازم!!!!
دیگه تحمل سرما و گرما که سهله، ولی قسمت خوب و شیرین ماجرا زمانیکه میایی خونه و عکسهایی که اینهمه واسش زحمت کشیدی رو می بینی و با تموم وجودت لذت می بری:گل:

سلام و صبح بخیر امیرمحسن عزیز
امیرجان به نظر میاد که هفته آینده رطوبت مناسبی تو منطقه ما باشه
نظرت راجع به بارش هفته آینده چیه عزیزجان؟
احتمال تقویت سیستم و تغذیه رطوبتی از منشا جنوبی هم میدی؟
متشکرم زیاد

سلام سعید جان و صبح زیبای شما هم بخیر
بنظر میرسه که سامانه هفته آینده با رطوبت به نسبت بهتری در مقایسه با سامانه روز گذشته در محدوده شمال شرق فعالیت خواهد کرد. و البته تا حدودی هم رطوبت مورد نیاز سامانه از طریق دریای سرخ تامین خواهد شد.
امیدوارم که بارشهای خوبی در انتظارمون باشه:گل:

Monster Storm Lashing Outer Reaches of Alaska
By Andrew Freedman
Follow @afreedma
An extraordinarily powerful ocean storm, packing hurricane-force winds and waves towering up to 62 feet, has been spinning its way toward Alaska's Aleutian Islands after undergoing a phenomenally rapid intensification process in the Western North Pacific Ocean since Sunday. This satellite image, which captured the storm near its peak intensity on Tuesday, offers a rare glimpse at a storm system of this magnitude.

At its most intense point, the storm had an air pressure reading of about 932 mb, roughly equivalent to a Category 4 hurricane, and more intense than Hurricane Sandy as that storm moved toward the New Jersey coastline in October. (In general, the lower the air pressure, the stronger the storm.) The storm's central pressure plunged by 48 to 49 mb in just 24 hours, making it one of the most rapidly intensifying storms at a mean latitude of 34°N since 1979, according to a data analysis by Ryan Maue of Weatherbell Analytics.
On Tuesday, the storm spanned a staggering 1,440 miles, according to David Snider, a meteorologist at the National Weather Service in Alaska. That's equivalent to the distance between Denver and New York City.

In Alaska, the National Weather Service has issued high wind warnings and hurricane force wind warnings for the sparsely populated, but strategically important central and western Aleutian Islands and surrounding coastal waters starting on Wednesday. “Tonight winds may howl up to 85 miles-per-hour over the western tip of Alaska in the Aleutian Islands,” the NWS said. Sustained winds are expected to be near hurricane force, or 74 mph, and waves of 40 feet or greater are expected to pound the western Aleutian Islands.
As of Wednesday morning, winds were already blowing as high as 72 mph at Eareckson Air Station on the island of Shemya, about 1,500 miles southest of Anchorage. That island is no stranger to extreme weather, considering that it sticks out far into the North Pacific, making it vulnerable to polar storms and storms coming northward from the Western Pacific. (The U.S. Air Force outpost located there isn't exactly the most coveted assignment in the U.S. military.)
The storm was well-forecast by computer models. This image shows the modeled wave heights from a computer model simulation on Jan. 13, valid for Jan. 15. The projection shows a large area of 50-60 foot waves associated with the storm.

Fortunately for Alaska, the Pacific superstorm is weakening as it moves northeast, and it is not expected to significantly impact the rest of the state. Alaska had a frigid start to the winter, but it has experienced a significant January thaw. An “atmospheric river” event brought tropical moisture to the state during the past week, with warm air turning snow to rain and freezing rain as far inland as Fairbanks. The 0.10 inches of rain that fell in Fairbanks on Monday was the most rain to fall there in a single January storm since 1963, the NWS said.

Southern Snowstorm Thursday, Thursday Night
By Alex Sosnowski, Expert Senior Meteorologist

More Sharing ServicesShare | Share on ******** Share on myspace Share on google Share on twitter
The caboose in a train of storms affecting the South will trend colder and deliver wintry precipitation farther east than its predecessors, including heavy snow for the mountains and some major population centers. Snow will reach part of the coastal mid-Atlantic as well.
The storm has the potential to down trees and power lines as well as make for difficult travel.
Part of the lower Mississippi and Tennessee valleys has been hit with two ice storms in as many days.
The third and final storm in the series will bring a change from rain to snow from west to east over part of the interior South beginning tonight west of the Appalachians, Thursday in the southern Appalachians and a mix of rain and snow to some areas east of the mountains Thursday night.
A wintry mix, including more ice, will occur Wednesday over part of the lower Mississippi Valley and gradually shift eastward Thursday from northern Louisiana, northern Mississippi and middle Tennessee and central Kentucky.
Rain will change to snow and push out of the mountains Thursday into Thursday night.
There is the potential for a heavy amount of snow, in excess of half a foot in the southern Appalachians later Thursday into Thursday night. With such a dynamic storm system, there could be thunder with the snow in some locations.
Heavy snow will fall in the Great Smoky Mountains and other areas in the South before the storm departs the mid-Atlantic coast late in the week. (Photos.com image)
Snow will fall and accumulate in northern Georgia at an elevation above 2,500 feet. Some wet snow can mix in several hundred feet below this level.
According to Meteorologist Mark Mancuso, "Some wet snow can mix in around Birmingham, Atlanta Virginia Beach and Elizabeth City, N.C."
As you head north the snow will become more extensive, lower in elevation and will reach east of the Appalachians. The mountains of North Carolina to southwestern Virginia could be on the receiving end of a foot of snow or more.
In Virginia, a swath of heavy snow may extend northeastward from the mountains to part of the Tidewater. Several inches of snow are possible for a large part of the Delmarva Peninsula and part of southern New Jersey.
Moderate snow could reach as far north as the Washington, D.C. and Baltimore areas. These cities will be on the northern edge of the accumulating snow.
"Cities that have the potential to receive several inches of snow include Knoxville and Bristol, Tenn., Asheville and Winston-Salem, N.C., Roanoke and Richmond, Va.," Mancuso added.
Raleigh-Durham and Charlotte, N.C. could receive an inch or so of snow.
Due to the recent warm weather, much of the snow will melt on roadways. However, where the snow comes down hard, over the bridges and overpasses and over the higher elevations, slippery travel is likely.
More details and maps on the southern snowstorm will be released by AccuWeather.com as they become available.
Prior to the snow or a wintry mix, additional heavy rain and incidents of flooding will continue to be centered over the southern Appalachians, but will reach westward and eastward to the foothills and beyond.

من هم قبول دارم که نقشه ها تا اون روزها تغییرات زیادی خواهند کرد ولی امیدوارم تغییرات به شکلی باشه که کلا ایران با بارشهای قابل ملاحظه ای مواجه بشه!:گل:
ولی این الگویی که الان در این نقشه ها دیده میشه از حدود 15 روز گذشته در نقش های جی اف اس و همچنین CFS در نقشه ها با شدت و ضعف به چشم میخورده و خدا رو شکر تا امروز که در خدمت تون هستیم از نقشه ها حذف نشده پس میشه در این خصوص خیلی امیدوار موند:گل:
