for 76% of the reported disasters in the region from 1950 to 2004 ( World Bank 2006 ). The ability to provide better understanding of TC behavior as well as seasonal climate outlooks prior to the TC season has the potential to benefit small island nations through increasing capacity to prepare for these extreme events, possibly saving lives and helping to mitigate impacts on civil infrastructure. The knowledge of how busy a particular season will be—and, more importantly, where in the basin TCs

in cold air outflows that affected blocking in the New Zealand region and ultimately the Southern Oscillation. L’Heureux and Thompson (2006) demonstrated a significant interaction between ENSO and the southern annular mode (SAM) during summer, showing the effect of ENSO is circumpolar and not confined to the South Pacific and West Antarctica. Here, we describe a teleconnection linking ENSO with a seasonally resolved sea salt record from the summit of Law Dome (LD), East Antarctica. To date

effects, resulting in hemispheric or even global responses in climate. Teleconnections are responsible for a significant proportion of Australasian climate variability, defined as the region of the southwest Pacific that includes Australia and New Zealand ( Fig. 1 ). Annual and subannual fluctuations in the Australasian atmosphere and ocean state have been linked to the El Niño–Southern Oscillation (ENSO) ( McBride and Nicholls 1983 ; Gordon 1986 ; Karoly 1989 ; Drosdowsky 1993 ; Mullan 1995

the model simulations reproduces the long-term preindustrial (501–1850 CE) cooling trend exhibited by the two hemispheric temperature reconstructions. One possible explanation for this is the response of the multiproxy network to orbitally induced changes in insolation. These changes largely cancel out on the annual and hemispheric scale but vary strongly as a function of both latitude and time of year ( Fig. 1a ). Any seasonal or geographical biases in the response of a proxy network might

at seasonal resolutions). Both sets of rainfall data were aggregated for the typical Australian water year that spans from 1 July to 30 June ( BoM 2012 ). b. Case study catchments The Border Rivers, Lachlan, upper Murray, and Wimmera catchments ( Fig. 1 ) were chosen as case study catchments of the MDB on which to develop our rainfall relationships used to locate useful potential/existing paleoclimate data. These catchments represent the northern, central, southeast, and southern MDB regions
