Global Scale Wave Model
Global-scale atmospheric waves with periods that are
subharmonics of a solar day and which propagate westward following the
apparent motion of the sun are known as migrating solar tides. These
waves are thermally forced by the periodic absorption of solar
radiation in the troposphere, stratosphere, mesosphere, and
thermosphere. Our steady-state 2-dimensional linearized global-scale
wave model (GSWM) extends from the ground to the thermosphere
and can be used to study tides as well as planetary waves throughout
the atmosphere. Recently, the seasonal variability of the migrating
diurnal and semidiurnal tides was investigated with the GSWM.
We highlight some of these results below. They are available to the
community at large via the NCAR CEDAR
Database.
