Figure 2. Mid-to-late autumn (April-May) rainfall linear trends across the Southern Hemisphere since 1951.

Figure 2

Rainfall linear trend for: (a) April-May using a four-rainfall product average (mm/year). The datasets used to calculate trends are CPC (1951–2010), GPCC (1951–2010), CRU (1951–2009), and UDel (1951–2010). The four rain gauges datasets are averaged to generate time series of rainfall (in mm/month) for: (b) southern Africa (average over 23°–35°E, 22°–34°S); (c) southeast Australia (130°–152°E, 31°–40°S); and (d) southern Chile (285°–290°E, 38°–47°S). The thick black lines in (b)–(d) denote 11-year (season) running averages. In (a), the semi-arid regions are shown in boxes and the 40°S midlatitude line is shown.
