RISARM-Led Improvements in Aerosols in Climate and Climate Models
Publisher: American Meteorological Society
Effect of Temperature Feedback and Hydrostatic Adjustment in a Stratospheric Model
Publisher: American Meteorological Society
Abstract: Calculated perturbations to stratospheric ozone are generally thought to be reduced when temperature feedback is included in the model. We find that when self-consistent hydrostatic adjustment is included with temperature ...
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 ...
Inclusion of Ice Microphysics in the NCAR Community Atmospheric Model Version 3 (CAM3)
Publisher: American Meteorological Society
Abstract: A prognostic equation for ice crystal number concentration together with an ice nucleation scheme are implemented in the National Center for Atmospheric Research (NCAR) Community Atmospheric Model version 3 (CAM3) with the ...
Atmospheric Ozone: Possible Impact of Stratospheric Aviation
Publisher: American Meteorological Society
Abstract: Models for stratosphere temperature and ozone are developed and shown to give good agreement with observational data. The atmosphere is in local radiative equilibrium at heights above about 35 km, and concentrations of ...
Block-Structured Adaptive Grids on the Sphere: Advection Experiments
Publisher: American Meteorological Society
Abstract: A spherical 2D adaptive mesh refinement (AMR) technique is applied to the so-called Lin?Rood advection algorithm, which is built upon a conservative and oscillation-free finite-volume discretization in flux form. The AMR ...
A Control-Volume Model of the Compressible Euler Equations with a Vertical Lagrangian Coordinate
Publisher: American Meteorological Society
Abstract: ccurate and stable numerical discretization of the equations for the nonhydrostatic atmosphere is required, for example, to resolve interactions between clouds and aerosols in the atmosphere. Here the authors present a ...
Observed Increase of TTL Temperature and Water Vapor in Polluted Clouds over Asia
Publisher: American Meteorological Society
Abstract: atellite observations are analyzed to examine the correlations between aerosols and the tropical tropopause layer (TTL) temperature and water vapor. This study focuses on two regions, both of which are important pathways ...
Integrating and Interpreting Aerosol Observations and Models within the PARAGON Framework
Publisher: American Meteorological Society
Abstract: Given the breadth and complexity of available data, constructing a measurement-based description of global tropospheric aerosols that will effectively confront and constrain global three-dimensional models is a daunting ...
CHASER: An Innovative Satellite Mission Concept to Measure the Effects of Aerosols on Clouds and Climate
Publisher: American Meteorological Society
Abstract: tion of cloud droplets on aerosol particles, technically known as the activation of cloud condensation nuclei (CCN), is the fundamental process driving the interactions of aerosols with clouds and precipitation. The ...
