A PDF-based parameterization of subgrid-scale hydrometeor transport in deep...
A parameterization scheme is proposed for the subgrid-scale transport of hydrometeors in an assumed probability density function (PDF) scheme. Joint distributions of vertical...- publication PDF

Characteristics of tropospheric ozone depletion events in the Arctic spring:...
Arctic ozone depletion events (ODEs) are caused by halogen catalyzed ozone loss. In situ chemistry, advection of ozone-poor air mass, and vertical mixing in the lower...- publication PDF

The Delta-Eddington Approximation for a Vertically Inhomogeneous Atmosphere
The delta-Eddington approximation of Joseph, Wiscombe, and Weinman (1976) is extended to an atmosphere divided up by internal levels into homogeneous layers. Flux continuity is...- publication PDF

Future streamflow regime changes in the United States: Assessment using...
Streamflow regimes are changing and expected to further change under the influence of climate change, with potential impacts on flow variability and the seasonality of extremes....- publication PDF

Conservation of dry air, water, and energy in CAM and its potential impact...
For the Community Atmosphere Model version 6 (CAM6), an adjustment is needed to conserve dry air mass. This adjustment exposes an inconsistency in how CAM6's energy budget...- publication PDF

Twentieth century Antarctic air temperature and snowfall simulations by IPCC...
We compare new observationally-based data sets of Antarctic near-surface air temperature and snowfall accumulation with 20th century simulations from global climate models...- publication PDF

An agent-based modeling framework for examining the dynamics of the...
Hurricane evacuations involve many interacting physical-social factors and uncertainties that evolve with time as the storm approaches and arrives. Because of these complex and...- publication PDF

A link between the hiatus in global warming and North American drought
Portions of western North America have experienced prolonged drought over the last decade. This drought has occurred at the same time as the global warming hiatus—a decadal...- publication PDF

Using sonic anemometer temperature to measure sensible heat flux in strong winds
Sonic anemometers simultaneously measure the turbulent fluctuations of vertical wind (w') and sonic temperature (Ts'), and are commonly used to measure sensible heat flux (H)....- publication PDF

Temperature acclimation of photosynthesis and respiration: A key uncertainty...
Earth System Models typically use static responses to temperature to calculate photosynthesis and respiration, but experimental evidence suggests that many plants acclimate to...- publication PDF

Shapes and aall orientations of ice particle aggregates
Testing the often-made assumption that ice particle aggregates (snowflakes) are well represented by oblate spheroids, ellipsoid fits are applied to aggregate images. An...- publication PDF

On the selection of localization radius in ensemble filtering for multiscale...
Covariance localization remedies sampling errors due to limited ensemble size in ensemble data assimilation. Previous studies suggest that the optimal localization radius...- publication PDF
