Temporal variations of satellite-observed outgoing longwave radiation over the winter monsoon region. Part II: short-period (4- 6 day) oscillations.

Abstract

Empirical orthogonal function analysis was applied to outgoing longwave radiation (OLR) data over three limited regions during the three winters of 1974-75, 1975-76 and 1976-77. Regional composite maps were constructed by truncating the eigenvector series of 4-6 day OLR anomalies for each winter at 70% representation. Based on these composite charts, an attempt was made to investigate the phase relationships between changes in truncated 4-6 day filtered OLR data at a selected reference point, and those in other areas within the same region. - from Author
