  • The Community Earth System Model Version 2 (Cesm2)

    Open AccessGökhan Danabasoglu, Jean‐François Lamarque et al.ARTICLEJournal of Advances in Modeling…2020

    An overview of the Community Earth System Model Version 2 (CESM2) is provided, including a discussion of the challenges encountered during its development and how they were addressed. In addition, an evaluation of a pair of CESM2 long preindustrial control and historical ensemble simulations is presented. These simulations were performed using the nominal 1° horizontal resolution configuration of the coupled model with both the “low‐top” (40 km, …

  • The Community Earth System Model (Cesm) Large Ensemble Project: A Community Resource for Studying Climate Change in the Presence of Internal Climate Variability

    Open AccessJennifer E Kay, Clara Deser et al.ARTICLEBulletin of the American…2015

    While internal climate variability is known to affect climate projections, its influence is often underappreciated and confused with model error. Why? In general, modeling centers contribute a small number of realizations to international climate model assessments [e.g., phase 5 of the Coupled Model Intercomparison Project (CMIP5)]. As a result, model error and internal climate variability are difficult, and at times impossible, to disentangle. I…

  • Effects of stratospheric variability on El Niño teleconnections

    Open AccessJadwiga H Richter, Clara Deser et al.ARTICLEEnvironmental Research Letters2015

    The effects of the tropical Pacific El Nino Southern Oscillation (ENSO) phenomenon are communicated to the rest of the globe via atmospheric teleconnections. Traditionally, ENSO teleconnections have been viewed as tropospheric phenomena, propagating to higher latitudes as Rossby waves. Recent studies, however, suggest an influence of the stratosphere on extra-tropical ENSO teleconnections. The stratosphere is highly variable: in the tropics, the …

  • Projected changes in regional climate extremes arising from Arctic sea ice loss

    Open AccessJames A Screen, Clara Deser et al.ARTICLEEnvironmental Research Letters2015

    The decline in Arctic sea ice cover has been widely documented and it is clear that this change is having profound impacts locally. An emerging and highly uncertain area of scientific research, however, is whether such Arctic change has a tangible effect on weather and climate at lower latitudes. Of particular societal relevance is the open question: will continued Arctic sea ice loss make mid-latitude weather more extreme? Here we analyse ideali…

  • Separating the stratospheric and tropospheric pathways of El Niño–Southern Oscillation teleconnections

    Open AccessAmy H Butler, Lorenzo M Polvani et al.ARTICLEEnvironmental Research Letters2014

    The El Niño–Southern Oscillation (ENSO) is a major driver of Northern Hemisphere wintertime variability and, generally, the key ingredient used in seasonal forecasts of wintertime surface climate. Modeling studies have recently suggested that ENSO teleconnections might involve both a tropospheric pathway and a stratospheric one. Here, using reanalysis data, we carefully distinguish between the two. We first note that the temperature and circulati…

  • Influence of projected Arctic sea ice loss on polar stratospheric ozone and circulation in spring

    Open AccessLantao Sun, Clara Deser et al.ARTICLEEnvironmental Research Letters2014

    The impact of projected Arctic sea ice loss on the stratosphere is investigated using the Whole Atmosphere Community Climate Model (WACCM), a state-of-the-art coupled chemistry climate model. Two 91-year simulations are conducted: one with a repeating seasonal cycle of Arctic sea ice for the late twentieth-century, taken from the fully coupled WACCM historical run; the other with Arctic sea ice for the late twenty-first century, obtained from the…

  • Uncertainty in climate change projections: The role of internal variability

    Open AccessClara Deser, Adam Phillips et al.ARTICLEClimate Dynamics2012

    Uncertainty in future climate change presents a key challenge for adaptation planning. In this study, uncertainty arising from internal climate variability is investigated using a new 40-member ensemble conducted with the National Center for Atmospheric Research Community Climate System Model Version 3 (CCSM3) under the SRES A1B greenhouse gas and ozone recovery forcing scenarios during 2000–2060. The contribution of intrinsic atmospheric variabi…
