It was cold in the Continental US the this week. Colder than Alaska, Mars (technically), which isn't so surprising because it is presently in Antarctica, but sounds wild nonetheless. You probably want to forget about the cold – but we won you.
The new gif of NASA's Atmospheric Infrared Sounder (AIRS) on the Aqua satellite is a depiction of the dramatic and deadly cold snap, demonstrating temperature plummeting to forty below zero. The weekly, called the polar vortex.
The Polar Vortex can be a one-of-a-kind, and rotating counterclockwise. The lower vortex is a low-pressure airmass.
The Jet Stream is a Band of Winds of the Polar Vortex. We saw this week. The stratospheric polar vortex is usually tighter and more confined around it. But when it gets disrupted or weakens, it can trigger cold triggers. The relationship isn't direct, though, according to the paper.
Since the behavior of the polar vortex deals, we can wonder if you can do it with it. Scientists have suggested a decrease in the amount of cold water in the Arctic as a result of the stratospheric vortex, or that is the jet stream. further south, leading to more cold air outbreaks at mid-latitudes. But this is still up for debate.
The AIRS map only shows the temperatures, rather than the air masses themselves. But we should give you an idea of the process, as well as the intense science.[via NASA/JPL]
