Space weather forecasting capability is six decades behind terrestrial weather forecasting," you will often hear at gatherings of scientists determined to understand the connections between our star and our home on Earth. It is an accurate statement in terms of capability.
The NCAR Whole Atmosphere Community Climate Model (WACCM), with a quasi-uniform horizontal resolution of $\sim$25km and a vertical resolution of 0.1 scale height, produces large horizontal winds and vertical shears maximizing in the mesosphere and lower thermosphere (MLT), similar to those found
Most of the large events affecting the thermosphere and ionosphere part of the space environment come from the Sun, the solar wind, and Earth’s magnetosphere, but even in “quiet time” periods lacking those sources of variability, conditions in the thermosphere and ionosphere continue to fluctuate
High resolution Whole Atmosphere Community Climate Model (WACCM) simulations are used to study how gravity waves vary during a stratospheric sudden warming (SSW) event from the source region to the lower thermosphere.
