Mapping the Polar Vortex

It is quite cold in America at the moment. For example in Park Rapids, Minnesota temperatures have fallen as low as -42F (-41C).

Joshua Stevens created the above visualization of the polar vortex, which is causing the extreme weather in the USA at the moment. The map uses seven days of GEOS-5 NASA EOSDIS Worldview data to show how the polar vortex has affected air temperature above the United States.

While some areas of America are experiencing subzero temperatures on the other side of the world Australia is sweltering under record high temperatures. In Adelaide, last week, the temperature topped a scorching 115.9F (46.6C). Joshua Stevens has got us covered again. Here is Joshua's animation of the same seven days of NASA data, this time showing air temperatures in Australia
