Enhanced Infrared Satellite from UNISYS. A very hot and destructive tropospheric system is moving hot air from the equator to the Arctic Circle. These are huge distributions. The hot air is forcing the arctic air down to the lower latitudes because it is heavier and sinks while the ligher, hotter air rises to displace it. The hotter air has more mass but less density than the arctic air and that is why the displacement is possible.
