Can a Convective Cloud Feedback Help to Eliminate Winter Sea Ice at High CO2 Concentrations?
Abbot, Dorian S.; Walker, Christopher; Tziperman, Eli (American Meteorological Society, 2009)Winter sea ice dramatically cools the Arctic climate during the coldest months of the year and may have remote effects on global climate as well. Accurate forecasting of winter sea ice has significant social and economic ... -
Continental constriction and oceanic ice-cover thickness in a Snowball-Earth scenario
Tziperman, Eli; Abbot, Dorian S.; Ashkenazy, Yosef; Gildor, Hezi; Pollard, David; Schoof, Christian G.; Schrag, Daniel P. (American Geophysical Union, 2012) -
Correlation between present-day model simulation of Arctic cloud radiative forcing and sea ice consistent with positive winter convective cloud feedback
Leibowicz, Benjamin D.; Abbot, Dorian S.; Emanuel, Kerry; Tziperman, Eli (American Geophysical Union, 2012)A positive feedback on winter sea-ice loss, based on warming due to radiative forcing caused by the onset of convective clouds in response to sea-ice loss, has recently been proposed. This feedback has thus far been ... -
Effects of explicit atmospheric convection at high CO2
Arnold, Nathan P.; Branson, Mark; Burt, Melissa A.; Abbot, Dorian S.; Kuang, Zhiming; Randall, David A.; Tziperman, Eli (National Academy of Sciences, 2014)The effect of clouds on climate remains the largest uncertainty in climate change predictions, due to the inability of global climate models (GCMs) to resolve essential small-scale cloud and convection processes. We compare ... -
A High-Latitude Convective Cloud Feedback and Equable Climates
Abbot, Dorian S.; Tziperman, Eli (Royal Meteorological Society, 2008)A convective cloud feedback on extratropical surface temperatures is identified in a zonally averaged two-level atmospheric model. The model contains simplified parametrizations for convection, precipitation, and clouds, ... -
Quantifying the Seasonal and Interannual Variability of North American Isoprene Emissions Using Satellite Observations of the Formaldehyde Column
Palmer, Paul I.; Abbot, Dorian S.; Fu, Tzung-May; Jacob, Daniel J.; Chance, Kelly V.; Kurosu, Thomas Paul; Guenther, Alex; Wiedinmyer, Christine; Stanton, Jenny C.; Pilling, Michael J.; Pressley, Shelley N.; Lamb, Brian; Sumner, Anna Louise (American Geophysical Union, 2006)Quantifying isoprene emissions using satellite observations of the formaldehyde (HCHO) columns is subject to errors involving the column retrieval and the assumed relationship between HCHO columns and isoprene emissions, ... -
Sea Ice, High-Latitude Convection, and Equable Climates
Abbot, Dorian S.; Tziperman, Eli (American Geophysical Union, 2008)It is argued that deep atmospheric convection might occur during winter in ice-free high-latitude oceans, and that the surface radiative warming effects of the clouds and water vapor associated with this winter convection ... -
Seasonal and interannual variability of North American isoprene emissions as determined by formaldehyde column measurements from space
Abbot, Dorian S.; Palmer, Paul; Martin, Randall; Chance, Kelly V.; Jacob, Daniel James; Guenther, Alex (Wiley-Blackwell, 2003)Formaldehyde (HCHO) columns measured from space by solar UV backscatter allow mapping of reactive hydrocarbon emissions. The principal contributor to these emissions during the growing season is the biogenic hydrocarbon ...
