RISClimate Sensitivity of the CSIRO GCM: Effect of Cloud Modeling Assumptions
Publisher: American Meteorological Society
Abstract: The climate sensitivity of the CSIRO Global Climate Model is investigated using uniform sea surface temperature perturbation experiments. One experiment (denoted DIAG) uses a diagnostic treatment of clouds, with fixed cloud ...
Retrieval of Three-Dimensional Particle Velocity from Airborne Doppler Radar Data
Publisher: American Meteorological Society
Abstract: A technique has been developed for the retrieval of three-dimensional particle velocities from Doppler data obtained with an airborne radar. The 95-GHz radar was mounted on the University of Wyoming KingAir aircraft. The ...
Sensitivity of the First Indirect Aerosol Effect to an Increase of Cloud Droplet Spectral Dispersion with Droplet Number Concentration
Publisher: American Meteorological Society
Abstract: Observations show that an increase in anthropogenic aerosols leads to concurrent increases in the cloud droplet concentration and the relative dispersion of the cloud droplet spectrum, other factors being equal. It has ...
Tropical Rainfall Trends and the Indirect Aerosol Effect
Publisher: American Meteorological Society
Abstract: An atmospheric global climate model coupled to a mixed layer ocean model is used to study changes in tropical rainfall due to the indirect effects of anthropogenic sulfate aerosol. The model is run to equilibrium for ...
Dual-Doppler Analysis in a Single Plane from an Airborne Platform
Publisher: American Meteorological Society
Abstract: A modified dual-Doppler analysis technique for use with airborne Doppler radars utilizing two fixed beams is presented. Although the data collected by such a system would ideally lie in the plane defined by the radar beam ...
Indirect Aerosol Forcing, Quasi Forcing, and Climate Response
Publisher: American Meteorological Society
Abstract: The component of the indirect aerosol effect related to changes in precipitation efficiency (the second indirect or Albrecht effect) is presently evaluated in climate models by taking the difference in net irradiance between ...
Vibration-Based Detection of Small-Scale Damage on a Bridge Deck
Publisher: American Society of Civil Engineers
Abstract: Vibration-based damage detection (VBDD) methods use damage-induced changes to the dynamic properties of a structure to detect, locate, and sometimes quantify the extent of damage. This paper describes a laboratory-based ...
A Scheme for Calculation of the Liquid Fraction in Mixed-Phase Stratiform Clouds in Large-Scale Models
Publisher: American Meteorological Society
Abstract: A scheme for calculation of the liquid fraction fl in mixed-phase stratiform clouds has been developed for use in large-scale models. An advantage of the scheme, compared to the interpolation in temperature that is typically ...
Meteorological Considerations Used in Planning the NEXRAD Network
Publisher: American Meteorological Society
Abstract: A systematic and objective approach was used to optimize the siting of the individual radars forming the Next Generation Weather Radar (NEXRAD) network. Prime consideration was given to meteorological factors in conjunction ...
Why Does Aerosol Forcing Control Historical Global-Mean Surface Temperature Change in CMIP5 Models?
Publisher: American Meteorological Society
Abstract: inear regression is used to examine the relationship between simulated changes in historical global-mean surface temperature (GMST) and global-mean aerosol effective radiative forcing (ERF) in 14 climate models from CMIP5. ...
