سلام
بارش هاي كه هم اكنون در شمال شرق كشور داريم ناشي از موج كوتاهي(Shortwave) است كه به تدريج بعد از عبور از ايران به يك كم فشار بريده(Cut of low) تبديل ميشود.
شب خوش.

امیر محسن جان وقتی این سیستم های شمالی فقط صرفا شمالی باشن و اصلا با جریان جنوبی همراهی نکنن تهران فقط و فقط باد میوزه و حتی قله توچال هم ابری نمیشه این و بار ها دیدم
امروز تهران کلا تا عصر ابری شد و برای دقایقی هم برخی نقاطش برف بارید و من مطمئنم که جریانات جنوبی کمی وجود داشته
قم هم که محمد جان گفت برف میباره
حالا باز شما استادید و بهتر میدونید . نظر من بود :خجالت2:

2012 Global Temps Rank in Top 10 Hottest On Record

By Andrew Freedman2012 was one of the 10 warmest years on record globally according to data released Tuesday from the National Oceanic and Atmospheric Administration (NOAA) and NASA. NOAA said that 2012 marked the 10th warmest year since records began in 1880, with a globally averaged annual temperature that was 1.03°F above average. NASA, using slightly different methods, found that it was the ninth-warmest year. NASA and NOAA independently keep track of Earth’s surface temperatures, and their records, along with other datasets all show a clear global warming trend during the latter half of the 20th century. Studies show this due in large part to manmade emissions of heat-trapping greenhouse gases, such as carbon dioxide.
Global temperature anomalies in degrees C averaged from 2008 through 2012.

The global annual temperature has increased at an average rate of 0.11°F per decade from 1880 to 2012, NOAA said, with the rate of increase accelerating in recent decades, to an average of 0.27°F per decade during the past 50 years. Including 2012, all 12 years during the 21st century have been among the 14 warmest on record, and only one year — 1998 — during the 20th century was warmer than 2012. According to NASA, with the exception of 1988, the nine warmest years in their 132 years of record keeping have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record. "One more year of numbers isn't in itself significant," NASA climatologist Gavin Schmidt said in a press release. "What matters is this decade is warmer than the last decade, and that decade was warmer than the decade before. The planet is warming. The reason it's warming is because we are pumping increasing amounts of carbon dioxide into the atmosphere." Although global temperatures continue to increase, there remains considerable year-to-year variability due to natural climate fluctuations, such as La Niña and El Niño events, which can help decrease or increase global temperatures even further. However, if the past two years are any indication, the manmade global warming signal may now be powerful enough to largely overcome the cooling influences of a La Niña.

During the first three months of 2012, La Niña conditions were present in the equatorial tropical Pacific Ocean, with cooler-than-average sea surface temperatures helping to hold down global temperatures. However, 2012 wound up besting 2011 for the warmest La Niña year on record. In addition, global average ocean temperatures also set a record for the warmest La Niña year. The warmest year in NOAA’s dataset, 1998, was an El Niño year, when unusually warm sea surface temperatures in the tropical Pacific added to the warming already taking place from the influence of greenhouse gases. The climate has continued to warm since 1998, and the consequences of that warming are becoming increasingly apparent. A new federal assessment of climate change impacts on the U.S. found that climate change is already having a wide range of negative impacts around the country, including longer lasting and more frequent extreme heat events and heavy precipitation events. In 2012, the U.S. had its warmest and second-most extreme year on record, and Arctic sea ice melted to record low levels. Between March 18 and September 16, 4.57 million square miles of Arctic sea ice melted — the largest ice loss of any melt season on record. Meanwhile, Antarctic sea ice extent hit the largest level on record, which is consistent with climate change projections that show the Antarctic should respond to global warming differently than the Arctic, due to the many geographical distinctions between the two poles and differences in ocean and atmospheric circulation in these areas. Northern Hemisphere snow cover extent in December 2012 was the largest on record, and snow cover during the winter of 2011-12 was also above average. However, spring snow cover extent has been declining in a trend that scientists have linked to manmade climate change and the loss of Arctic sea ice. While winter Northern Hemisphere snow cover has grown at a rate of about 0.1 percent per decade, spring Northern Hemisphere snow cover has shrunk by about 2.2 percent. Most parts of the world experienced warmer-than-average annual temperatures, including much of North and South America, most of Europe and Africa, and western, southern, and extreme northeastern Asia. Much of Alaska, far western Canada, central Asia, the eastern and equatorial Pacific, and areas of the Southern Ocean, among others, were cooler than average. While 2012 saw near-average precipitation across the globe, there were many precipitation extremes that inflicted a heavy toll in terms of their death toll and economic impact. Major drought occurred in the U.S., eastern Russia, Ukraine, and Kazakhstan, as well as in northeastern Brazil. A wetter-than-average rainy season in western and central Africa affected 3 million people across 15 countries from July to October. And in the U.K., conditions swung from record dryness in March to record wetness in April, NOAA said.

بارش تو غرب مشهد یک مقدار درشتر و شدیدتر شد ، آسمون هم کاملا یک دست و قرمز هست .
فقط یک ذره ابرها پایین تر بیاد و مه آلود بشه خیلی خوب میشه

سلام مجدد به دوستان
سمت ما که همینطوری برف میاد و نمیشینه
البته اینکه در معابر اصلی برف ننشسته اینه که فکر کنم علاوه بر گرم بودن آسفالت نسبت به سایر سطوح ، مقداری نمک هم هنوز از برف قبلی معابر هست حالا من تو خیابونها امشب ترددی نداشتم اما ممکنه که محلول پاشی هم کرده باشن
