WebJan 1, 2014 · Spectral analysis allows to learn about the climate physics. The task is to estimate the spectral density function and to test for harmonic (cyclical) signals. This poses more difficulties than, for example, linear regression because now we estimate a function and not just two parameters. WebSpectral analysis techniques proved to be very useful tools when evaluating the influence of different climate patterns on the regional meteorology and climate of Cordillera Blanca. The common periodicities found, both in the meteorological records and in the records of the different patterns, could be indicative of contemporaneity and joint ...
