	Interpreting low-frequency modes of Southern Hemisphere atmospheric variability as the rotational response to divergent forcing Monthly Weather Review; 9/1/2001; Revell, Michael J; Kidson, John W; Kiladis, George N; 1910 words ; ABSTRACT The principal modes of Southern Hemisphere low-frequency variability have recently been calculated using a 39-yr record of 300-hPa streamfunction fields from the NCEP-NCAR reanalysis dataset. The authors attempt to interpret these modes as the rotational response to some divergent forcing. Read more
