درود دوستان

امروز خدا رو شکر به سورس عظیمی از نقشه های ماهواره ای مربوط به ایران دسترسی پیدا کردم که در این تصاویر همه چیز پیدا میشه برف و یخبندان- دشت کویر-طوفان شن- موج سرما- تصویر ماهواره ای آلوده ترین روز تهران- تصاویر ماهواره ای واقعی از نواحی زلزله زده ایران قبل و بعد از وقوع و .... خلاصه از شیر مرغ تا جون آدمیزاد و از اونجائیکه سایت مذکور با قند شکن باز میشه در آینده ای نزدیک و پس از سر جمع کردن این تصاویر مجموعه گلچینش رو در وبلاگ هوای مشهد قرار خواهم داد:گل:

در اینجا دو تا تصویر رو بعنوان نمونه میذارم:

[SIZE=-1]An unusually severe blizzard swept over Iran on January 8, 2008, bringing extreme cold and deep snow to much of the desert country reported BBC News. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this pair of the images of the snow on January 9. The lower image shows Iran as it would appear to a person looking at it from space. White snow clings to the mountains in a long east-west arc across the country. The full extent of the snow cover is difficult to gauge, however, because of the clouds that linger over the region. It is difficult to distinguish the white snow from the white clouds.

[SIZE=-1] The top image provides a better idea of where snow accumulated during the blizzard. The image was made with both visible light and short-wave infrared. This particular combination of light energy makes snow and ice pop out, since the frozen water is red, while clouds range from white to orange. The snow cover clearly affected several Iranian cities, including Tehran, Esfahan and Kerman. Fingers of snow stretch far into the southern desert, where snow had not previously been seen in living memory, reported BBC news. According to BBC news, 28 people died because of cold or car crashes related to the unusually heavy snowfall.

[/SIZE]Cold Snap in Southwest Asia - NASA (January 17 - 24, 2008)


Biting cold seized much of southwest Asia throughout January and into February 2008. This image illustrates how much colder temperatures were between January 17 and January 24, 2008, compared to previous years. The image shows land surface temperatures—how cold or hot the land is to the touch—compared to average land surface temperatures in January 2000-2007. In 2008, land surface temperatures were as much as 20 degrees Celsius cooler than in previous years. The overall blue tone of the image reveals cold temperatures throughout the region, but the most intense cold was in Iran, Afghanistan, Turkmenistan, Uzbekistan, and Tajikistan.
The extreme winter conditions were the worst in decades in both Afghanistan and Tajikistan. In Afghanistan, the cold left more than 750 people and 230,000 cattle dead, reported Reuters. Many families rely on cattle for food security, and their loss will likely cause great hardship. Tajikistan was similarly taxed by the severe cold. Even as cold temperatures increased the demand for electricity, power production decreased when inlet streams feeding hydroelectric power plants froze, said the United Nations Office for the Coordination of Humanitarian Affairs on February 11. Tajikistan derives 76 percent of its electricity from hydropower, said the UN. The power shortages left urban areas without heat.

مثلا این توضیح مربوط به بارش سنگین برف در زمستان سال 2005 هست که تصویر ماهواره ایش هم در نوع خودش جالبه:

[HIGHLIGHT]Heavy snow settled over Iran on January 23, 2005, closing roads and isolating many northern villages. [/HIGHLIGHT][HIGHLIGHT]The snow fell heaviest in the northern Zagros Mountains, where as much as 75 cm (32 inches) fell in a single night, but the white extends south along the spine of the mountains almost to the Persian Gulf[/HIGHLIGHT]. The snow also covers the Alborz range in the northeast. Located along the southern front of the Alborz mountains, Iran's capital, Tehran, was also blanketed with snow.

This true-color image of the snow-covered region was acquired on January 26, after the clouds had largely cleared from the region. It appears that the snow extends across the border into Turkey and northern Iraq, though clouds make it difficult to see the extent of the snow cover in Turkey.
The same weather system that brought snow to Iran also triggered a massive dust storm in the Persian Gulf states. Dust from the storm settled on the snow in western Iran, near the Iraqi border, giving the snow-covered mountains a slightly tan tint.

وقوع طوفان و تگرگ سنگین در سانتا روزا- ایالت San Miguel

Hail storm hammers, swamps Santa Rosa

Updated: Thursday, 04 Jul 2013, 6:26 PM MDT
Published : Thursday, 04 Jul 2013, 6:12 PM MDT

SANTA ROSA, N.M. (KRQE) - A storm dumped inches of hail on Santa Rosa Wednesday evening leaving a lot of ice and damage in its wake.
The storm, which moved in from San Miguel County, lasted for about an hour.
Thursday morning, Santa Rosa still looked like a winter wonderland from the air. Ice blanketed the streets, parks and rooftops on the Fourth of July, the morning after the storm that dumped 3-6 inches of nickel- to golf-ball-sized hail that accumulated to feet in depth in some places.
"It's funny to see the people at Park Lake all in shorts and stuff and swimming trunks, and in the snow, it seems like," Horacio Lopez said.
Santa Rosa's fire chief said while he appreciates the moisture during the long-running drought, the storm caused dangerous conditions on roadways.
"Some people I talked to were stuck for five to six hours," Chief Gilbert Romero said. "It's just really bad, something I've never seen in my 50 years of life. I've never seen anything like this."
Some of the original stained glass windows, dating back about 100 years, at St. Rose of Lima Catholic Church were damaged by the hail.
Resulting water damage also forced businesses to close including the Family Dollar as people continued to shovel hail off of roofs.
"We've just spent the morning here trying to assess our damage," Mario Trujillo, the owner of the Sun & Sand Restaurant, said. "Just looking at town, it's just incredible. We've heard of carports falling."
Roberta Blea didn't realize her carport had fallen on all three of her family's cars until after the storm passed. She said the falling hail was so loud, they couldn't hear the carport collapsing.
"I looked out and it was just raining hail," Blea told KRQE News 13. "I had never seen that happen. I just never even expected this much destruction. It's devastating."
Forecasters with the National Weather Service said these types of hail storms aren't uncommon, but that it's rare for this to happen before monsoon season starts.

عیب نداره نوید جان . ولی توصیم به بچه های تهران اینه که یکم کوه و اینچیزا برن . زندگی در قرون ما همش ماشینی هست و با این وضع زندگی ، فشار ها استرس ها و هزار جور مسئله دیگه عمر ها کم شده و بدن زود فرسوده میشه . از پنجاه سالگی ارتوروز و دیسک و کمر درد و حتی بیماری های خطرناک که خدا نکنه کسی بگیره داره برای ملت رخ میده .

هفته ای یکبار پیاده روی در طبیعت میتونه خیلی کمک کنه که بدن ادم فرسوده نشه و از این هیاهوی زندگی ماشینی و خیلی از ادمایی که حال ادم ازشون بهم میخوره دوری کنه
