Relationship among Seasonal Cycles, Low-Frequency Oscillations, and Transient Disturbances as Revealed from Outgoing Longwave Radiation Data
Publisher: American Meteorological Society
Abstract: Applying harmonic analyses to outgoing longwave radiation (OLR) data, harmonics m = 1 to 15 were computed for each year in 1975?77 and 1979?83. The sum of the first three harmonics (m = 1 to 3), referred to as Y(t), ...
Eastward Propagation of 30–60 Day Perturbations as Revealed from Outgoing Longwave Radiation Data
Publisher: American Meteorological Society
Abstract: Some of the characteristic features of low-frequency oscillations were investigated by applying an extended empirical orthogonal function (EEOF) analysis to 30?60 day filtered outgoing longwave radiation (OLR) data during ...
