Good thing for the northerners that winter coincides with the perihelion. Too bad the jet stream over the north east USA has brought the new catch word for weathermen. Polar vortex. Some days will struggle to break 0F/ -18C.

Just had to google why it's winter when we are closest to the sun - always assumed we were further away when winter hit - apparently the difference in distance makes no difference, it's all to do with duration of light we get in the northern hemisphere and angle the light hits (more direct and absorbed in summer, more at an angle and not as much gets through to hit any point in our winter).

Due to the earths axial tilt.
