(geophysics)
Periodic global motions of the earth's atmosphere, produced by gravitational action of the sun and moon; amplitudes are minute except in the upper atmosphere.

It may be interesting to consider the variations with time of the atmospheric oscillation parameters published by different experiments.
We used F to assess the atmospheric oscillation conditions that favoured the bycatches event for loggerhead or leatherback turtle.
The main goal of this study is to analyse interannual variability in data of bycatch of loggerhead and leatherback turtles from Spanish Mediterranean longline fishery and subsequentlytest the possible relationship between the CPUE (catch per unit effort, measured in thousands of hooks) of these turtles and the atmospheric oscillations.
This clear-cut conclusion provides a solid incentive for the water resources planners to consider the large-scale atmospheric oscillation patterns like the Southern Oscillation and/or North Atlantic Oscillation for planning and managing purposes.
The modern lake water balance is evaluated using a numerical lake model and stable isotope analysis, and then both the lake surface area and water balance are compared to the local and regional climate records (surface air temperature, precipitation, and regional atmospheric oscillation indices).
A comparison of the P-E index and lake surface area variations with atmospheric oscillations affecting the northern Yukon can help to determine whether the observed spatio-temporal variations are affected by these natural oscillations.
