Biennial variations in surface temperature over the United States as revealed by singular decomposition.

Abstract

Surface temperature variations over the contiguous US during the period 1931-75 are examined using mean monthly averages for the 344 climate divisions. This data matrix is decomposed into orthogonal components using the method of singular decomposition. 2 areas of maximum QBO amplitude are indicated; 1 over the NE US, and a less distinct area over the southwestern US. -from Authors
