Relationships of Australian Sugarcane Yields to Various Climatic Variables

摘要: The relationship between the sugarcane yield anomalies in northeastern Australia and various atmospheric oceanic variables is examined with help of three different climatological data sets, Comprehensive Ocean-Atmosphere Data Set (COADS), Southern Hemisphere Analyses set (SHANAL) Tabulated (TDS). Correlation coefficients 10 yields are presented for lags up to twelve months prior harvest. results suggest that show strongest positive (negative) response anomalous sea surface temperature (SSTA) mean level pressure (MSLPA) changes occurring central eastern Pacific during austral spring 7 These correlations accompanied by an opposite pattern located north Australia. At same time, strength zonal components winds can be found over western tropical (positive correlations) Indian Ocean (negative correlations). patterns characteristic El Nino-Southern Oscillation (ENSO) signal support findings a previous Index (SOI)-oriented study. However, maximum SSTA MSLPA substantially higher (around |0.8|) than those reached SOI (−0.65). Furthermore, it appears large-scale circulation indices better indicators regional (Cairns) variables. at Cairns highly significant (values |0.5| |0.6|), but generally confined summer only.
