Tropical Pacific decadal variability (TPDV) has been a persistent research topic for over two decades. Despite this long-standing interest, the underlying ocean dynamics determining the timescale and associated variance remain […]
Atmospheric carbon dioxide concentration has increased by 50% since the preindustrial era. The excess carbon that has accumulated in the atmosphere constitutes about 40% of the total carbon emitted by […]
Earth system science has made great progress on understanding the atmosphere, biosphere and hydrosphere, but has failed to functionally incorporate its most dynamic component: the global human system. Yet, this […]
Many of the Intergovernmental Panel on Climate Change’s Special Report for Emission Scenarios and Representative Concentration Pathways (RCP) projections (especially RCP 8.5 and 6) project CO2 emissions due to oil […]
Models for biological and epidemiological processes run the gamut from phenomenological to mechanistic, including differing amounts of biological information and detail. In this talk, I explore models across this spectrum […]
The oceanic data assimilation (DA) system, essential for understanding and forecasting global climate variabilities, blends prior information from numerical models with observed data to create the best possible estimates and […]
AI machine learning has attracted more and more attentions for climate science in recent years with expanding applications to many areas. In this talk, I will briefly present our recent […]
Oxygen levels are decreasing in the ocean at an alarming rate, leading to the expansion of Oxygen Minimum Zones (OMZs) particularly in the eastern part of the tropical Atlantic and […]
We investigate the origin of the equatorial Pacific cold sea surface temperature (SST) bias and its link to wind biases, local and remote, in the Kiel Climate Model (KCM). The […]
