variable: precipitation
variableDetail: amount@surface
direction: negative
scope: climate
seasonality: Dec-Feb
basis: "Having discounted the above-mentioned possibilities, the δ18O values in the Angelica record can be interpreted as rainfall strength of the SACZ based on several key lines of evidence... The regional climate is dominantly tropical semi-arid with over 70% of its annual rainfall occurring in the austral summer months from November to March due to the seasonal development of the SACZ, which is established during the mature summer monsoon months from December to February (DJF)."
