An assessment of relationships between the Australian subtropical ridge, rainfall variability, and high‐latitude circulation patterns
Abstract The monthly anomaly of the latitude of the subtropical ridge over eastern Australia (L) is a major regulator of synoptic‐scale influences on Australia's climate. Three datasets have been used to calculate L: observed Australia coastal mean sea level pressure (MSLP), Hadley and NCEP Rea...
