A Brief Story Deep Tropical Convection contribution to climate change
Direct Human Influence Dumping Waste Heat into the Surface Layers of the Ocean
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 Catastrophic Level 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
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.
