Effects: Main driving mechanism for tropical large-scale atmospheric circulation Cloud formation from DTC influences the Earth’s radiation budget Vertical redistribution of water vapor produces the water vapor feedback loop for global warming SST increases likely result in more vigorous DTC activity thus influencing the above – but the data for this is somewhat ambiguous
Relevant Data Difference between black and blue determines DTC activity – sharp spike in 1997 is due to strong El Nino event – data indicates that since 2000, the gap is, on average larger than in prior decades Catastrophic Level
Ocean Atmosphere Coupled System Major Unknown: Role of Deep Sea Transport – is the rate changing?
A Recently Discovered Coupled Event Large Scale disturbances in the equatorial ocean waters can persist and spatially transmit over the period of 1-2 months. The physics behind this remains mysterious.
Computational Research at UO Mapping SST and structural changes in DTC into predictions Can do this now because of a unique UO resource in terms of computational power. Recently ran 100 days simulation (about 2 weeks of real time) at 20 minutes of time resolution (this is a world record) that produced 7200 data files of combined storage 1.8 TB – but this is now easily handled.
