Does the Moon & Sun have a tidal effect on the atmosphere as well as the oceans?
It is the gravitational attraction of the sun and moon that cause waters of the ocean to raise and lower at different parts of the earth. Tides occur in oceans, and to a much smaller extent, tides also occur in large lakes, in the atmosphere, and within the solid crust of the earth. There are also non-astronomical factors, such as the configuration of the coastline, the local depth of the water, the ocean-floor topography, and other hydrographic and meteorological influences that play an important role in altering the range and interval between high and low water.
The moon is a major influence on the Earth’s
tides, but the sun also generates considerable tidal forces. Solar tides
are about half as large as lunar tides and are expressed as a variation
of lunar tidal patterns, not as a separate set of tides. When the sun,
moon, and Earth are in alignment (at the time of the new or full moon),
the solar tide has an additive effect on the lunar tide, creating
extra-high high tides, and very low, low tides—both commonly called
spring tides. One week later, when the sun and moon are at right angles
to each other, the solar tide partially cancels out the lunar tide and
produces moderate tides known as neap tides. During each lunar month,
two sets of spring tides and two sets of neap tides occur (Sumich, J.L.,
1996).
