RISThe Influence of Ground Moisture Conditions in North America on Summer Climate as Modeled in the GISS GCM
Publisher: American Meteorological Society
Abstract: A new general circulation model, developed to run on a coarse grid (8 ? 10° resolution) at the Goddard Institute for Space Studies is employed to investigate the potential use of ground moisture anomalies for seasonal ...
The Consequences of Not Knowing Low- and High-Latitude Climate Sensitivity
Publisher: American Meteorological Society
Abstract: Along with the continuing uncertainty associated with global climate sensitivity [2°?4.5°+, for doubled CO2 in the latest Inter-governmental Panel on Climate Change (IPCC) report], we have not made much progress in improving ...
The Dynamics of Warm and Cold Climates
Publisher: American Meteorological Society
Abstract: The atmospheric dynamics of five different climate simulations with the GISS GCM are compared to investigate the changes that occur as climate warms or cools. There are two ice age simulations, the current and doubled CO2 ...
Stratospheric Aerosol and Gas Experiment II CD-ROM Atlas of Global Monthly Aerosols, Ozone, NO2, Water, Vapor, and Relative Humitidy (1985–1993)
Publisher: American Meteorological Society
Abstract: Individual profile measurements from the Stratospheric Aerosol and Gas Experiment II (SAGE II) instrument aboard the Earth Radiation Budget Satellite have been used to create latitude-longitude maps of monthly mean aerosols, ...
Microbaroms and the Temperature and Wind of the Upper Atmosphere
Publisher: American Meteorological Society
Abstract: Microbaroms are regular pressure variations of a few microbars (dyn cm?2) produced by the passage of infrasound (?5 see period) radiated from ocean waves. Their amplitudes show prominent diurnal, semidiurnal and seasonal ...
The GISS Global Climate-Middle Atmosphere Model. Part II. Model Variability Due to Interactions between Planetary Waves, the Mean Circulation and Gravity Wave Drag
Publisher: American Meteorological Society
Abstract: The variability which arises in the GISS Global Climate-Middle Atmosphere Model on two time scales is reviewed: interannual standard deviations, derived from the five-year control run, and intraseasonal variability as ...
Climate Change and the Middle Atmosphere. Part II: The Impact of Volcanic Aerosols
Publisher: American Meteorological Society
Abstract: The effects of volcanic aerosols on the middle atmosphere are investigated with the Goddard Institute for Space Studies (GISS) Global Climate/Middle Atmosphere model. Volcanic aerosols with a visible optical depth of 0.15 ...
Climate Change and the Middle Atmosphere. Part I: The Doubled CO2 Climate
Publisher: American Meteorological Society
Abstract: The impact of doubled atmospheric CO2 on the climate of the middle atmosphere is investigated using the GISS global climate/middle atmosphere model. In the standard experiment, the CO2 concentration is doubled both in the ...
The Role of Sea Ice in 2×CO2 Climate Model Sensitivity. Part I: The Total Influence of Sea Ice Thickness and Extent
Publisher: American Meteorological Society
Abstract: As a first step in investigating the effects of sea ice changes on the climate sensitivity to doubled atmospheric CO2, the authors use a standard simple sea ice model while varying the sea ice distributions and thicknesses ...
