Fluctuations are primarily a response to local ET and the magnitude and timing of the fluctuation differs with well depth, vegetation and soil conditions, climate, and distance from a surface-water source.
Annual fluctuations in water level measured in each of the shallow wells and in Peterson Reservoir are summarized by ET unit in table 8.
Typical changes measured in the daily response show that the magnitude of the daily fluctuation generally decreased as the water table began declining in response to continuing or increasing ET, and that at greater depths, the phase in the daily fluctuation was shifted from that of the ET.
Primordial fluctuations are density variations in the early universe which are considered the seeds of all structure in the universe.
Adiabatic fluctuations are density variations in all forms of matter and energy which have equal fractional over/under densities.
As with scalar fluctuations, tensor fluctuations are expected to follow a power law and are parameterized by the tensor index (the tensor version of the scalar index), and the ratio of the tensor to scalar power.
