Robust multiyear climate impacts of volcanic eruptions in decadal prediction systems
Major tropical volcanic eruptions have a large impact on climate, but there have only been three major eruptions during the recent relatively well-observed period. Models are...- publication PDF

Atmospheric boundary layers over an oceanic eddy
Imagery and numerical modeling show an abundance of submesoscale oceanic eddies in the upper ocean. Large-eddy simulation (LES) is used to elucidate eddy impacts on the...- publication PDF

Global expansion of wildland-urban interface (WUI) and WUI fires: insights...
Fires in the wildland-urban interface (WUI) are an important issue globally. To understand the change of WUI, we develop a 9 km worldwide unified wildland-urban interface...- publication PDF

Magnetosphere sawtooth oscillations induced by ionospheric outflow
The sawtooth mode of convection of Earth's magnetosphere is a 2- to 4-hour planetary-scale oscillation powered by the solar wind-magnetosphere-ionosphere (SW-M-I) interaction....- publication PDF

Uncertainties in climate responses to past land cover change: First results...
Seven climate models were used to explore the biogeophysical impacts of human-induced land cover change (LCC) at regional and global scales. The imposed LCC led to statistically...- publication PDF

Competing forecast verification: Using the power-divergence statistic for...
When testing hypotheses about which of two competing models is better, say A and B, the difference is often not significant. An alternative, complementary approach, is to...- publication PDF
