Simulations with the Community Earth System Model 2 using the Whole Atmosphere Community Climate Model configuration, known as CESM2(WACCM6), show evidence of dynamical coupling from the high latitudes of the winter middle atmosphere to the tropics and the middle and high latitudes of the summer

The NASA Global-scale Observations of the Limb and Disk (GOLD) instrument is an ultraviolet imager and spectrograph that observes light from the upper-atmosphere of the Earth, in order to infer quantities such as the composition and temperature of the thermosphere.

Patel et al. observe that when an interplanetary shock launched from the Sun arrives at Earth, it compresses the dayside magnetic field and an impulse in electric and magnetic field propagates as a characteristic wave mode inside the magnetosphere toward the nightside.
