Tropical Indian Ocean Canary of the Global
Warming?! Yan Du and Shang-Ping Xie (IPRC/UH Met)
The tropical Indian Ocean emerges as a region of
the most robust warming of the global ocean, a
trend captured by all IPCC AR4 models.

Satellite Altimeter (T/P)
The advent of satellite altimetry and the Earth
Simulator made it possible to study variability
of narrow jets like KE for the first time

• ? Full-physics coupled model that successfully
  keeps the ITCZ north of the equator.
• To become portable to other regions for climate
  downscaling and process studies.
