Global atmospheric effects of massive smoke injections from a nuclear war: results from general circulation model simulations

  title={Global atmospheric effects of massive smoke injections from a nuclear war: results from general circulation model simulations},
  author={Curt Covey and Stephen Henry Schneider and Starley L. Thompson},
We report three-dimensional calculations of regional and global climatic effects of smoke generated by a large-scale nuclear war. Tropospheric aerosols of absorption optical depth 3, when injected into Northern Hemisphere mid-latitudes and maintained for 1–3 weeks, cause intense radiative heating of the mid-troposphere with substantial surface cooling over land. Mid-latitude surface temperatures in continental interiors can drop well below freezing in a matter of days regardless of season. Our… 
Protracted climatic effects of massive smoke injection into the atmosphere
Climate perturbations caused by sudden injections of aerosols into the atmosphere have received increased attention with the realization that fires started by a nuclear war might release sufficient
Climatic response to large atmospheric smoke injections: Sensitivity studies with a tropospheric general circulation model
A tropospheric general circulation model is coupled with a Lagrangian trace species transport and removal model to determine the climatic response to continental-scale smoke injections arising from
Importance of local mesoscale factors in any assessment of nuclear winter
There is a possibility that severe climate perturbations would follow a major nuclear war (the ‘nuclear winter’) due to the injection of large amounts of smoke into the atmosphere1–6. Given
“Nuclear winter”: A diagnosis of atmospheric general circulation model simulations
We investigate the adiabatic and diabatic thermal balance of an atmospheric general circulation model (GCM) under two conditions: the control case, representing today's atmosphere, and a “nuclear
Influence of Solar Heating and Precipitation Scavenging on the Simulated Lifetime of Post—Nuclear War Smoke
The behavior of smoke injected into the atmosphere by massive fires that might follow a nuclear war was simulated and it was showed that heating of the smoke by sunlight would be important and might produce several effects that would decrease the efficiency with which precipitation removes smoke from the atmosphere.
Two‐dimensional simulations of possible mesoscale effects of nuclear war fires: 1. Model description
The two-dimensional mesoscale meteorological model and the aerosol model described in the companion paper by Giorgi [this issue] are used to investigate mesoscale effects induced by atmospheric

It has recently been suggested that following a nuclear exchange there might be a significant reduction in surface temperature over land areas, due to the impact upon the radiation budget of the
Dynamical and radiative response to the massive injection of aerosol from Kuwait oil burning fires
The effects of the injection of large amount of soot comparable to that produced in the burning of oil wells in Kuwait were studied using a 2-D mesoscale model. During the three day numerical
Climate and smoke: an appraisal of nuclear winter.
The latest understanding of nuclear winter is reviewed, and serious new environmental problems associated with soot injection have been identified, including disruption of monsoon precipitation and severe depletion of the stratospheric ozone layer in the Northern Hemisphere.
Global interactive transport simulations of nuclear war smoke
Global circulation model simulations are reported in which smoke created by fires following a large nuclear war is allowed to move with the model winds. A substantial fraction of smoke generated over


Nuclear Winter: Global Consequences of Multple Nuclear Explosions
The potential global atmospheric and climatic consequences of nuclear war are investigated using models previously developed to study the effects of volcanic eruptions, finding long-term exposure to cold, dark, and radioactivity could pose a serious threat to human survivors and to other species.
January and July Simulations with a Spectral General Circulation Model
Abstract We describe the results of January and July simulations carded out with a nine-level spectral model, employing a rhomboidal truncation at wavenumber 15. Sea-surface temperature, sea-ice
The Response of a Spectral General Circulation Model to Refinements in Radiative Processes
Abstract We present here results and analyses of a series of numerical experiments performed with a spectral general circulation model (GCM). The purpose of the GCM experiments is to examine the role
Climate modeling through radiative‐convective models
We present a review of the radiative-convective models that have been used in studies pertaining to the earth's climate. After familiarizing the reader with the theoretical background, modeling
A parameterization for the absorption of solar radiation in the earth's atmosphere
Abstract A method is described for rapidly computing the amount of solar energy absorbed at the earth's surface and in the atmosphere as a function of altitude. The method is a parametric treatment,
