15 of 12 Dates Meeting Info Presentation info TIWs affect ocean, climate, biogeochemistry Aquarius reveals TIWs salinity structure for the 1 st time from space). Brings new understanding to TIWs. Lee, Lagerloef, Gierach, Yueh, Dohan (2012, June GRL) SSS from Aquarius (color shading), SST (contours in a), surface currents (arrows in b) on Dec. 11, 2011 (7-day maps) PSU Aquarius Captures Pacific TIWs Reynolds ¼-deg OI OSCAR
16 of 12 Dates Meeting Info Presentation info The black contours are 100 mm/month isolines. H.Kao &G.Lagerloef, JGR-Oceans in prep, 2013 October 2012 monthly averages Above: Aquarius SSS gradients reveal prolific frontal structures that are not evident in Argo OI maps. Dark contour is 34.6 isohaline. Below: Differences between the maps above show (left) that satellite SSS are biased low relative to Argo in high rain regions, and (right) frontal patterns unresolved by Argo. Fronts

20 of 12 Dates Meeting Info Presentation info Summary Proposed SPURS-2 site is in zonal band of strongest seasonal SSS variability EOFs show peak SSS amplitude at ~130W; ~ 0.5 psu amplitude. Coincides with null point in quadrature phase EOF2 Seasonal cycle is lightly asymmetrical over the year; max SSS in March, min SSS in October Interannual variations; SSS under the ITCZ in Year 2 (Sep12- Aug13) was significantly less than in Year 1 (Sep11-Aug12). Proposed site is in the climatological shear zone between NECC and NEC Fronts varied seasonally and interannually; strongest during the wet season.
