این نرم افزار Weather Display پنج دقیقه باهاش ور رفتم
گویا برا کسایی خوبه خودشون یه ایستگاه هواشناسی دارند و این برنامه با اتصال به اون میتونه اطلاعاتش رو تو اینترنت منتشر کنه.
البته قابلیت اتصال به ایستگاه های دیگه از طریق آی پی و پورت اونا با دونستن رمز عبور هم داره.
در کل کارش پردازش اطلاعات تجهیزات هواشناسی و ارسال و دریافتشون از طریق شبکه محلی ، اینترانت یا اینترنته.

Nuclear Power Cannot Compete with Cheap Shale Gas
By Paul Brown, Climate News Network
LONDON – Nuclear power stations in Canada and the United States are closing because they cannot compete with cheap power being produced from shale gas.
This revolution in the way North America produces its electricity is sending shock waves through the nuclear industry in Europe too. New nuclear build will be spectacularly uneconomic if a fracking industry is successful in the United Kingdom.

Gas prices would tumble as they have across the Atlantic. Even the existing nuclear stations in France, Belgium and the UK would find themselves struggling to compete, especially if they need investment to achieve modern safety standards.
A report, expected to be published shortly by the UK Government, shows that the country may have massive gas reserves that can be released by fracking. It is a controversial technology because of environmental concerns about water contamination and earthquakes, but it promises cheap power, far cheaper than even the most optimistic new nuclear station operator could offer.
If the leaked reports that the British Geological Survey has dramatically increased its estimate of the amount of gas available in the UK are correct, then reserves are 200 times greater than originally thought. This is enough for more than a century of British needs and will cut gas prices across Europe.
[h=3]Priced out This kind of bonanza in the U.S. has made gas generation cheaper than coal, resulting in a reduction in coal-fired generation there and a fall in coal prices internationally. The switch to gas has led to a temporary drop in U.S. greenhouse gas emissions from the power industry, because gas is a cleaner fuel than coal.
In the long run, however, a large supply of cheap gas undercutting both renewables and nuclear will be a serious threat to international attempts to tackle climate change.
Nuclear power, supported by the UK government chiefly as a low carbon technology that is important to the energy mix, would be priced out of the market.
An example of what may happen in Europe if fracking gets under way is the decision on the Gentilly-2 reactor in Quebec. The low price of generation from gas obtained by fracking – four to five cents a kilowatt hour – puts the nuclear power plant at a competitive disadvantage. Its current production price is nine cents and it needs a $4.3 million refurbishment.
This makes it uneconomic to update. According to the Montreal Gazette Thierry Vandal, president of Hydro-Quebec which owns the reactor, told a national assembly committee hearing that “shale gas killed Quebec’s only nuclear reactor.”
The financial analysts Bloomberg say six nuclear stations are at risk of “early retirement” in the U.S. for the same reason. Duke Energy has decided to close the Crystal River Unit 3 plant in Florida rather than repair it, and Dominion Resources Inc’s Kewaunee reactor in Wisconsin is closing. The future of four other reactors is being reviewed.

In the UK the program to build at least eight new reactors has hit trouble because a series of potential backers has pulled out – the latest of them Centrica, the largest electricity supplier in the country.
It had a 20 percent stake in plans by EDF, the French nuclear giant, to build four new reactors in England. With costs escalating and delays, the company wrote off the $309 million it had already spent on the project and said that instead it was to concentrate on gas generation and renewables (see the report of 5 February).
[h=3]Subsidies banned EDF is looking for new partners and is in talks with the UK government to try to get a minimum price for electricity from the new stations. This is to be a guarantee for investors so that they will get their money back.
The trouble is that the European Union bans subsidies, so the government will have trouble avoiding legal action if it props up nuclear power. The nuclear industry is reported to need a price of $155 a megawatt hour for 30 years for its electricity to get a reasonable return on its investment, while the current price is around $93.
If EDF built four reactors that would cost householders and businesses about $1.5 billion a year in higher bills, a decision not likely to be popular.
The nuclear industry’s current plans are to build four of the European Pressurised Reactors at two sites in England. The two under construction in Finland and France are years late and billions over budget. There was another blow this week (Monday, February 11) when the Finnish plant, the prototype, was delayed again, until 2016.
It was started in 2005 and was supposed to be connected to the grid first in 2009, then in 2012. The start date was then put back in 2012 to “beyond 2014,” and the cost rose from 3 billion euros ($4B) to more than 6 billion.

Snowstorm Headed For Heart of Drought Region
By Andrew Freedman
Follow @afreedma
A major snowstorm is poised to deliver much-needed precipitation to areas from central and southern California to the Rockies and Plains states during the next several days. Parts of Kansas and Nebraska — ground zero for the worst drought conditions in the U.S. — may pick up more than a foot of snow by the time the storm ends there late Thursday.
Probability that 6 inches or more of snow will accumulate between Wednesday and Thursday morning across the U.S.

While the storm is not expected to deliver blockbuster snow totals, any precipitation — be it in the form of rain, snow, or the often dreaded “wintry mix” — will be a welcome sight in much of the West and Plains.
According to the most recent U.S. Drought Monitor, 77 percent of Nebraska is experiencing “exceptional” drought conditions, the most severe category. In Kansas, that figure is lower but still quite high, at 36 percent of the state.
More than a foot of snow is predicted along the I-80 corridor in central Nebraska, down to the I-70 corridor in Kansas. A foot or more of snow is also possible in the Sierra Nevada mountains, where snowpack has been running at about 75 percent of normal for this time of year, according to the California Cooperative Snow Surveys.
The U.S. Drought Monitor shows widespread drought in the West, Southwest, and Plains, including several states that will see snow from this storm.

While welcome news, the storm will not deliver nearly enough precipitation to end the drought. Typically, a 10-inch snowstorm would be equivalent to about 1 inch of liquid precipitation, and many parts of Nebraska and Kansas need more than 12 inches of rain to overcome their long-term precipitation deficit. In addition, most of the snow is predicted to fall in central and southern Nebraska, bypassing the northern and eastern parts of the state, which are locked in exceptional drought conditions.
In addition to the Plains states, the storm is also forecast to bring significant snow to the mountains of Utah, Colorado, New Mexico, and Arizona, which will be a boon to skiers. Heavy snow is also forecast to fall in Iowa, Missouri, and South Dakota, before the storm weakens and heads for the Midwest. Chicago is expected to see its largest snowstorm of the winter so far, with 2-to-4 inches predicted.
In addition, the storm may set off a severe thunderstorm outbreak across the South as warm, humid air from the Gulf of Mexico clashes with cold, dry air moving southward from Canada. Sleet and freezing rain also threaten to disrupt travel in areas just to the south and east of the heaviest snowfall, across Missouri, Oklahoma, and Arkansas, in particular.

خوب نقشه های ECMWF تا روز شنبه آپدیت شدند و همانطوریکه انتظارش رو داشتم بارشها رو مثل مدل جی اف اس به شدت کاهش داده و بارشهای امروز - پنجشنبه و جمعه در صورتیکه تحقق پیدا کنه در اثر جریانات همرفتی محلی و به شکل رگبار های پراکنده و خفیف با احتمال وقوع رعد و برق در حدود 40 درصد هست!

خوب این نقشه CAPE بر اساس مدل EcMWF برای امشب هست.عرض کنم خدمت تون از بعداز ظهر امروز به تدریج ابرهای کومولونیمبوس در اثر فراهم شدن شرایط همرفت در دو باند شمالی و جنوبی شهر شکل خواهند گرفت و این شرایط برای امشب بنظرمیرسه که بر روی شهر مشهد به تکوین میرسه و بارشهایی رو به شکل رگبار باران و با احتمال رعد و برق خواهیم داشت. وقتی این نقشه رو به دقت نگاه میکنیم کامل متوجه میشیم که سطح شهر بارش خوبی داره ولی خود رشته کوههای بینالود بغیر از بخش مرکزی و غربی اون که میشه در مجاورت شهر مشهد بارش آنچنانی نداره.
در واقع باید بگم اگه امشب بارشی در مشهد رخ بده 100 درصد در وهله اول مدیون بینالود و در وهله بعدی مدیون هزار مسجد هست:
نقشه کیپ امشب در منطقه خراسان:
نقشه کیپ امشب در همون بازه زمانی با زوم بالاتر برای دشت مشهد:
وقتی ما میگیم در سطح شهر مشهد و خصوصا نواحی غربی و جنوبی شهر بارش خوبی رخ میده ولی فرودگاه بارش کمی رو ثبت میکنه دقیقا علتش در تصویر بالا مشخص و مبرهن هست ولی خوب بعضی از دوستان در شهرهای دیگه این مسئله واسشون عجیب و غریب بنظر میرسه و خیلی سخت میتونند باور کنند که مشهد غربش خوب بباره ولی شرقش اندک
