Does the Siberian Weather with its Polar Wind Stream Affect North American Weather?
The impact of global weather, particularly polar wind, is now only being considered, as the many areas of the world seem to be changing with the warmer and colder weather we have been seeing in the last few years. It is often shown to be warmer in North America, when it is colder in Siberia and parts of Asia and Europe. For the most part, the polar wind has shifted in a way in the winter of 2011-2012, that benefits warmer winter conditions for North America. The lack of precipitation, colder winter days and nights, has been very evident for the winter of 2011 and 2012.
Polar Wind Stream is the Arctic Oscillation Effect
Polar Wind Impacts North America
Changes in the atmosphere are not always just based on pacific weather systems like El Niño or La Nina. The Southern Oscillation Effect, or El Nino, is the pacific wind that impacts North America mostly in the winter, but it can impact a summer condition as well. Blamed for weather in the west and the southern parts of America and Mexico, this warm water mass, can bring an impact on the jet stream, and how much moisture it travels across.
Similarly, in the polar wind stream or the Arctic Oscillation Effect, the winds are contained by the pressure variations around the northern polar cap. When the pressures are positively phased, the coldest air is kept near the polar caps, or over the Siberian Deserts and Mountains. The areas of Scandinavia and Northern Alaska see great precipitation and cold.
Eventually the Polar Wind Changes
As the positive effects of the arctic oscillation moves in a negative phase, the northern trade winds, push their moisture to the North American jet stream, and the wet, cold effect is felt. The winter snows, and cold temperatures that this phase creates is a common effect that most of North Canada and that Northern United States have prepared for. Alaska winters in this phase can be mild, and there will be more wet conditions across the Colorado and Nebraska Plains.
The change in negative phases recently, has ensured that their were more colder temperatures, but the fact that the soil temperatures have stayed fairly warm this winter during the Polar Wind positive phase, as shown that the remainder of 2011 and 2012 will be warmer than the 2010-2011 winter was in contrast.
Global Warming or Polar Wind Normal Oscillation?
So is this weird wind convergence the beginning of the global warming trend? The fact is, we are currently at the warmest average temperature that has ever been recorded, with a new average of 1 degree of warmth in average global temperature. The scientists that are predicting the global warming trend, see this as an a very ominous predictor of a warming trend to continue. The fact that our population on earth continues to expand, and our limited resources are becoming visibly restricted in poorer parts of the world, shows that the growth of warming will continue.
Polar winds are only one part of the puzzle to predicting weather, but they are a great global predictor of dire weather changes in the near and long term of future weather impacts to come.

WSI Launches WSI WindCast? – Weather Solutions Leader Enters Worldwide Wind Power Arena, Growth Market For Energy Traders, Wind Farm Operators and Utilities
Andover, MA (PRWEB) February 10, 2009
Weather Services International (WSI), the most trusted global weather solutions provider, today announced the launch of WSI WindCast™, a statistical forecasting system for the energy market, providing wind power and wind speed forecasts for wind farms anywhere in the world.
Developed in response to increased worldwide demand for wind power generation forecasting, WSI WindCast provides highly skillful, hourly forecasts (up to seven per day) that include weather-related parameters such as: wind speed, wind direction, atmospheric pressure and temperature, all at turbine height. It then uses these values in combination with additional techniques to deliver wind power forecasts up to seven days out.
“Wind power is rapidly becoming an important alternative energy source for the production of electricity. Energy traders, as well as wind farm operators, understand that the most critical meteorological aspect of wind power forecasting is the highly accurate prediction of wind speed at turbine height,” said Ira Scharf, General Manager of WSI’s Energy and Risk Division. “WSI WindCast not only delivers expert measurement and prediction of wind speed, but also provides precise wind power forecasts as a result of its proven techniques.”
Background
WSI WindCast is based on a proven forecasting model developed by WSI in 2004 to predict wind speed for wind farms across Europe, Asia and North America. In use since 2004 and consistently outperforming industry standard benchmarks, this wind speed model has been continually enhanced and currently forms the foundation of the WSI WindCast product.
Market
The use of wind power is growing by double digit percentages around the world. According to the Global Wind Energy Council (GWEC):
“…EU wind power [installations in Germany, France, Spain, Italy and the United Kingdom], according to… Platts PowerVision and EWEA, in 2007, made up 40% of total new power installations, representing the fastest growing power generating technology in Europe. … The EU aimed to increase the share of electricity produced from renewable energy sources (RES) … to 21% by 2010…”
“…The U.S. wind energy industry shattered all previous records in 2007, installing 5,244 megawatts (MW) and expanding U.S. wind power generating capacity by 45%. … new wind projects accounted for about 30% of the entire new power-producing capacity added in the U.S. in 2007, establishing wind power as a mainstream option for new electricity generation…”
“…China is the world’s fastest growing wind energy market, with an average annual growth rate of 56% in the past seven years. … Based on the current growth rates, the Chinese Renewable Energy Industry Association (CREIA) forecasts a capacity of around 50 GW by 2015…”

WSI Launches Tools For Worldwide Wind Power Arena
Andover, MA (PRWEB) May 4, 2009
Weather Services International (WSI), the most trusted global weather solutions provider, today announced WSI WindCast™, a wind speed and power forecasting product, plus an innovative alerting service for the wind power marketplace. Visit WindPower 2009, booth #5882, in Chicago May 4-7, to learn more.
WSI WindCast is a graphics-based, statistical, forecasting system for the energy market providing wind power and wind speed forecasts for wind farms anywhere in the world. WSI’s new alerting service provides warnings when lightning, thunderstorms or other severe weather events are approaching wind farm locales.
Developed in response to increased worldwide demand for wind power, WSI WindCast provides highly accurate, hourly forecasts that include weather-related parameters such as: wind speed, wind direction, atmospheric pressure and temperature, all at turbine height. Using these predictions, WSI WindCast then provides accurate wind power forecasts, up to seven days out.

Energy traders, as well as wind farm operators, understand that the most critical meteorological aspect of wind power forecasting is the highly accurate prediction of wind speed at turbine height,” said Ira Scharf, General Manager of WSI’s Energy and Risk Division. “WSI WindCast not only delivers expert measurement and prediction of wind speed in a graphical, easy to understand format, but also provides precise wind power forecasts as a result of its proven techniques.”
WSI’s lightning alert service continuously monitors the North American Precision Lightning Network, providing immediate notification via SMS text message and/or email, as well as on-screen, audible and visual alerting. It then issues all-clear messaging after the threat has subsided. WSI also plans to provide another service alerting users about conditions that may result in the formation of ice on wind turbine blades.
