RISAtmospheric Pressure Variation and the Climate of Mars
Publisher: American Meteorological Society
Abstract: If Mars has permanent CO2 polar caps, atmospheric heat transport may cause the atmospheric pressure to be extremely sensitive to variations of solar heating at the poles. This could happen because atmospheric heating depends ...
A Global Average Model of Atmospheric Aerosols for Radiative Transfer Calculations
Publisher: American Meteorological Society
Abstract: A global average model of the size distribution, chemical composition and optical thickness of stratospheric and tropospheric aerosols is proposed. The uncertainties involved in making the model are emphasized, and some ...
A Case Study of Mobilization and Transport of Saharan Dust
Publisher: American Meteorological Society
Abstract: Numerical models of the atmosphere and aerosols are used to investigate mobilization and transport of Saharan dust over West Africa and the tropical Atlantic Ocean for 23?28 August 1974. We have found that mobilization ...
A Model for Particle Microphysics, Turbulent Mixing, and Radiative Transfer in the Stratocumulus-Topped Marine Boundary Layer and Comparisons with Measurements
Publisher: American Meteorological Society
Abstract: A detailed 1D model of the stratocumulus-topped marine boundary layer is described. The model has three coupled components: a microphysics module that resolves the size distributions of aerosols and cloud droplets, a ...
Smoke and Dust Particles of Meteoric Origin in the Mesosphere and Stratosphere
Publisher: American Meteorological Society
Abstract: A height profile of ablated mass from meteors is calculated, assuming an incoming mass of 10?16 g cm?2 s?1 (44 metric tons per day) and the velocity distribution of Southworth and Sekanina, which has a mean of 14.5 km s?1. ...
Estimates of the Climatic Impact of Aerosols Produced by Space Shuttles, SST's, and other High Flying Aircraft
Publisher: American Meteorological Society
Abstract: Aircraft and Space Shuttles flying through the stratosphere over the next several decades will add sulfuric acid and aluminum oxide particles, respectively, to this region of the atmosphere. To evaluate the effect of these ...
A One-Dimensional Model Describing Aerosol Formation and Evolution in the Stratosphere: II. Sensitivity Studies and Comparison with Observations
Publisher: American Meteorological Society
Abstract: We have performed sensitivity tests on a one-dimensional physical-chemical model of the unperturbed stratospheric aerosols and have compared model calculations with observations. The sensitivity tests and comparisons with ...
Effects of Aerosols on Cloud Albedo: Evaluation of Twomey’s Parameterization of Cloud Susceptibility Using Measurements of Ship Tracks
Publisher: American Meteorological Society
Abstract: Airborne measurements from the Meteorological Research Flight?s Hercules C-130 and the University of Washington?s Convair C-131A during the Monterey Area Ship Track field project are used to evaluate Twomey?s analytic ...
The NASA Airborne Tropical Tropopause Experiment: High-Altitude Aircraft Measurements in the Tropical Western Pacific
Publisher: American Meteorological Society
Abstract: he February?March 2014 deployment of the National Aeronautics and Space Administration (NASA) Airborne Tropical Tropopause Experiment (ATTREX) provided unique in situ measurements in the western Pacific tropical tropopause ...
