During the 2014 January polar vortex, more than 20 people across the country died from the cold as places like Georgia — which rarely see serious cold — dealt with lows under 10 degrees ...
[15] The second presidential inauguration of U.S. President Ronald Reagan was held in the United States Capitol Rotunda instead of outside, due to the cold weather, and the inaugural parade was cancelled. Since Inauguration Day fell on a Sunday, Ronald Reagan took a private oath on January 20, 1985, and the semi-public oath on January 21, 1985 ...
A quasi-permanent phenomenon referred to as the polar vortex may have been partly responsible for the cold weather. Temperatures in much of the United States dropped 15 to 35 °F (8.3 to 19 °C) below average by November 19, following a southward "dip" of the polar vortex into the eastern two-thirds of the country.
A polar diagram could refer to: Polar area diagram, a type of pie chart; Radiation pattern, in antenna theory; A diagram based on polar coordinates; Spherical coordinate system, the three-dimensional form of a polar response curve; In sailing, a Polar diagram is a graph that shows a sailing boats potential wind speed over a range of wind and ...

As with the Mercator projection, the region near the tangent (or secant) point on a Stereographic map remains very close to true scale for an angular distance of a few degrees. In the ellipsoidal model, a stereographic projection tangent to the pole has a scale factor of less than 1.003 at 84° latitude and 1.008 at 80° latitude.
The average temperature in Boston for January was 2.9 °F (1.6 °C) below the 1981–2010 normal, and the average temperature in February was 19.0 °F (−7.2 °C), which was 12.7 °F (7.1 °C) below the 1981–2010 normal, making it the second-coldest month of any month all-time, behind February 1934.
A third choice is the Gaussian polar chart, which correctly represents radial distances, but distorts transverse distances and angles. There are other possible charts; the article on spherically symmetric spacetime describes a coordinate system with intuitively appealing features for studying infalling matter.
