lunar atmospheric tide

lunar atmospheric tide

[′lü·nər ‚at·mə‚sfir·ik ′tīd]
(meteorology)
An atmospheric tide due to the gravitational attraction of the moon; the only detectable components are the 12-lunar-hour or semidiurnal component, as in the oceanic tides, and two others of very nearly the same period; the amplitude of this atmospheric tide is so small that it is detected only by careful statistical analysis of a long record.

Lunar atmospheric tides are thought to be weak, but could create favorable conditions for storms to strengthen.
