Deep Tropical Convection contribution to climate change
Slide 2
Dumping Waste Heat into the Surface Layers of the Ocean
Slide 3
Deep Tropical Convection/Atmospheric Rivers
Slide 4
Effects: Main driving mechanism for tropical large-scale
atmospheric circulation Cloud formation from DTC influences the
Earths 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
Slide 5
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
Slide 6
Ocean Atmosphere Coupled System Major Unknown: Role of Deep Sea
Transport is the rate changing?
Slide 7
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.
Slide 8
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.
