Quiet-time day-to-day variability of equatorial vertical E × B drift from...
Ionospheric day-to-day variability is ubiquitous, even under undisturbed geomagnetic and solar conditions. In this paper, quiet-time day-to-day variability of equatorial...- publication PDF

Air pollution and associated human mortality: The role of air pollutant...
Increases in surface ozone (O₃) and fine particulate matter (≤2.5 μm aerodynamic diameter, PM2.5) are associated with excess premature human mortalities. We estimate changes in...- publication PDF

Thermodynamic control of anvil cloud amount
General circulation models show that as the surface temperature increases, the convective anvil clouds shrink. By analyzing radiative–convective equilibrium simulations, we show...- publication PDF

Modeling sustainability: Population, inequality, consumption, and...
Over the last two centuries, the impact of the Human System has grown dramatically, becoming strongly dominant within the Earth System in many different ways. Consumption,...- publication PDF

Improving canopy processes in the Community Land Model version 4 (CLM4)...
The Community Land Model version 4 (CLM4) overestimates gross primary production (GPP) compared with data-driven estimates and other process models. We use global, spatially...- publication PDF

Mesh refinement
We study mesh refinement techniques for first-order hyperbolic equations. A refinement method for use with the leap-frog scheme is defined and its stability established. The...- publication PDF

Predictability and dynamics of tropical cyclone rapid intensification...
Rapid intensification (RI) of tropical cyclones (TCs) remains one of the most challenging issues in TC prediction. This study investigates the predictability of RI, the...- publication PDF

On the correspondence between seasonal forecast biases and long-term climate...
The correspondence between mean sea surface temperature (SST) biases in retrospective seasonal forecasts (hindcasts) and long-term climate simulations from five global climate...- publication PDF

Climate variability, volcanic forcing, and last millennium hydroclimate extremes
Multidecadal hydroclimate variability has been expressed as "megadroughts" (dry periods more severe and prolonged than observed over the twentieth century) and corresponding...- publication PDF

Formaldehyde evolution in US wildfire plumes during the Fire Influence on...
Formaldehyde (HCHO) is one of the most abundant non-methane volatile organic compounds (VOCs) emitted by fires. HCHO also undergoes chemical production and loss as a fire plume...- publication PDF

Distributions of ice supersaturation and ice crystals from airborne...
Ice supersaturation (ISS) is the prerequisite condition for cirrus cloud formation. To examine multiscale dynamics' influences on ISS formation, we analyze in situ aircraft...- publication PDF

Instantaneous longwave radiative impact of ozone: An application on...
Ozone is an important greenhouse gas in terms of anthropogenic radiative forcing (RF). RF calculations for ozone were until recently entirely model based, and significant...- publication PDF

Pacific decadal variability: Paced by Rossby basin modes?
A systematic study is presented of decadal climate variability in the North Pacific. In particular, the hypothesis is addressed that oceanic Rossby basin modes are responsible...- publication PDF
