EL NIÑO/SOUTHERN OSCILLATION (ENSO) DIAGNOSTIC DISCUSSION (CLIMATE PREDICTION CENTER/NCEP October 5, 2006) SST departures in the Niño regions all greater than +0.5 Oceanic and atmospheric anomalies are consistent with the early stages of El Niño
ENSODIAGNOSTIC DISCUSSIONCLIMATE PREDICTION CENTER/NCEP October 6, 2005 Statistical and coupled model predictions indicate El Niño conditions for the remainder of 2006 and into the NH spring (SH fall) 2007.
Tropical Moored Array GTS • All moorings on multi-sat • Increased duty cycle (8 16 hours/day)
Vandalism Buoys move and sensors fail. Fishing boats often found near buoys and fishing gear in moorings.
TAO Enhancements • SSS on all TAO moorings in 2007 • Heat, fresh water and momentum flux at 4 equatorial TAO sites (165ºE, 170ºW, 140ºW, 110ºW) • Support OceanSITES program
TAO Transition • TAO Data Processing and Distribution at NDBC since Oct 2005 • Parallel Testing completed in Sep 2006 • NDBC assumes responsibility for field operations in Jan 2007 • Prototype “refreshed” moorings deployed in spring 2007 • PMEL responsible for preparation and maintenance of ATLAS instrumentation
PIRATA Enhancements • SW Extension – Brazil/US. 2005 • Heat, momentum and fresh water flux measurements on 3 moorings - 2006 • NE Extension - AOML/PMEL added 2 moorings in 2006. Additional 2 moorings in 2007. • SE Extension – 2006. 1 year only. South Africa (U. Capetown). France and US.
2006 PIRATA Enhancements • NE Extension to improve understanding and prediction of tropical Atlantic variability • Region of Atlantic cyclone development 11.5ºN 23ºW HELENE
2006 PIRATA Enhancements 15ºN 38ºW HELENE
PIRATA Issues • PIRATA Review: • Should PIRATA continue? • Restructure responsibilities? • Ship requirements • Vandalism Ron Brown, May-June 2006 • K. Armah and colleagues. • University of Ghana
Indian Ocean Status • 2000/2001 JAMSTEC deployed 2 TRITON and 1 subsurface ADCP and has maintained sites. • 2004 PMEL/NIO/NCAOR deployed 4 ATLAS and 1 subsurface ADCP from Sagar Kanya • 2006 PMEL/NIO/NCAOR deployed 5 ATLAS and 1 subsurface ADCP from Sagar Kanya • 2006 PMEL/BPPT to deploy 2 ATLAS from Baruna Jaya I • 2006 JAMSTEC MISMO Experiment • 2007 PMEL/IRD/IFREMER to deploy 1 ATLAS (Flux) and 1 subsurface ADCP from Suroit for CIRENE • 2007 PMEL/? (BPPT?, FIO?) proposed subsurface ADCP
Indian Ocean Data Oct 2004 – Oct 2005 22 month long ADCP raw data record reveals seasonal and intraseasonal near surface current variability Oct 2005 – Sep 2006
Indian Ocean Issues • Vandalism is a serious problem • 3 of surface moorings not recovered • New/modified mooring design? • 22 month deployments are well beyond mooring design lifetime and contribute to lower data quality and quantity • Adequate and regular ship time is necessary to build and maintain the array
