Dust emission response to climate in Southern Africa
The processes which act in mineral dust source regions and factors which contribute to interannual variability within dust plumes emanating from them are poorly understood. In...- publication PDF

Upscale versus “up-amplitude” growth of forecast-error spectra
Atmospheric predictability is measured by the average difference (or "error") within an ensemble of forecasts starting from slightly different initial conditions. The spatial...- publication PDF

Mechanisms of along-valley winds and heat exchange over mountainous terrain
The physical mechanisms leading to the formation of diurnal along-valley winds are investigated over idealized three-dimensional topography. The topography used in this study...- publication PDF

Interactive Computing on the IBM 4341
The SCD computing system is complex, and it is difficult to disguise that complexity without impairing function. The IBM 4341 system is flexible; it is possible therefore to...- publication PDF

Mechanisms of stratospheric and tropospheric circulation response to...
The impact of projected Arctic sea ice loss on the atmospheric circulation is investigated using the Whole Atmosphere Community Climate Model (WACCM), a model with a well-...- publication PDF

How changes in the tilt angle of the geomagnetic dipole affect the coupled...
The orientation of the Earth's magnetic field has changed dramatically during the geological past. We have investigated the effects of changes in dipole tilt angle on the...- publication PDF

Mesoscale effects on carbon export: A global perspective
Carbon export from the surface to the deep ocean is a primary control on global carbon budgets and is mediated by plankton that are sensitive to physical forcing. Earth system...- publication PDF

The path to CAM6: Coupled simulations with CAM5.4 and CAM5.5
This paper documents coupled simulations of two developmental versions of the Community Atmosphere Model (CAM) towards CAM6. The configuration called CAM5.4 introduces new...- publication PDF

Extreme poynting flux in the dayside thermosphere: Examples and statistics
With the launch of the Defense Meteorological Satellite Program F-15 spacecraft in late 1999, data for calculating Earth-directed, magnetospheric Poynting flux became available...- publication PDF

Earth's energy imbalance
Climate change from increased greenhouse gases arises from a global energy imbalance at the top of the atmosphere (TOA). TOA measurements of radiation from space can track...- publication PDF

Cultivating a culture of inclusivity in heliophysics
A large number of heliophysicists from across career levels, institution types, and job titles came together to support a poster at Heliophysics 2050 and the position papers for...- publication PDF

The role of the particle size distribution in assessing aerosol composition...
Variations in the chemical composition of atmospheric aerosols alter their hygroscopicity and can lead to changes in the cloud-active fraction of the aerosols, or cloud...- publication PDF

Semi-parametric discrete choice measures of willingness to pay
A semi-parametric discrete choice method is proposed to recover welfare measures from individual choice data. The estimation procedure and properties of the proposed welfare...- publication PDF

Global distribution and interannual variations of mesospheric and lower...
On the basis of the TIDI mesospheric and lower thermospheric neutral wind observations from 2002 (March) to 2007 (June), we analyze the interannual variations of nonmigrating...- publication PDF

Mars upper atmospheric responses to the 10 September 2017 solar flare: A...
We report the first global, time‐dependent simulation of the Mars upper atmospheric responses to a realistic solar flare event, an X8.2 eruption on 10 September 2017. The Mars...- publication PDF

Role of green roofs in reducing heat stress in vulnerable urban...
Green infrastructure, such as green roofs, is increasingly being used to reduce 'heat stresses' associated with urban heat island effects. This article discusses strategies to...- publication PDF

Climatological analysis of tropical cyclone intensity changes under moderate...
Although infrequent, tropical cyclones (TCs) can intensify under moderate vertical wind shear (VWS). A potential hypothesis is that other factors-associated with both the TC and...- publication PDF
