A 7-Year Lag Precipitation Teleconnection in South Australia and Its Possible Mechanism

open access: yesFrontiers in Earth Science, 2020
Precipitation teleconnections with large-scale ocean–atmosphere oscillation systems provide useful information for water management. Here, we present a 7-year lag response in South Australia (SA) precipitation to the Southern Annular Mode (SAM) in a ...
