Abstract
The first six Chebyshev polynomial coefficients (i.e.,A 08 ,A 01 ,A 10 ,A 11 ,A 02 , A20) were derived from monthly mean geopotential height over East Asia for the period 1951–1983. Spectral analysis of these coefficients reveals relative maxima of power in the frequency bands of 200 months (≈ 16.7 years), 25 months (the quasi-biennial oscillation), 5–6 months, and 2–3 months. Cross-spectral characteristics between Chebyshev coefficients and the Southern Oscillation Index (SOI) were also explored. Coherence spectrum for the zonal and meridional circulation index (A 01 andA 10 ) with the SOI was significant near 4 years, the QBO, and 2–3 months. Some physical explanations were offered for the spatial linkages (i.e., teleconnections) between the SO and atmospheric circulation anomalies over East Asia.
