Chemistry-Climate Interactions

Collaborators: Prof. Dave Thompson, Colorado State University; Prof. Susan Solomon, Massachusetts Institute of Technology

• We try to quantify the influencs of chemistry-climate interactions on climate variability. We examine two simulations run on the WACCM4: A “free running” simulation that includes fully coupled chemistry-climate interactions; and a “specified chemistry” version of the model forced with prescribed climatological-mean chemical composition.

Air-Sea Interactions

Collaborators: Prof. Dave Thompson, Colorado State University; Dr. Lantao Sun, Colorado State University; Dr. Casey Patrizio, Colorado State University

• We assess the observed lead-lag relations between the atmospheric circulation and extratropical SST anomalies in two sets of simulations run on the CESM1: 1) a simulation run on a fully coupled version of CESM1 and 2) a simulation forced with prescribed, time-evolving SST anomalies over the extratropics. I have run the latter simulations with the CAM5 forced with realistic SST perturbation over the Kuroshio-Oyashio Extension region to study the atmospheric response to the extratropical SSTs.

Barotropic/Baroclinic Annular Modes

Collaborators: Prof. Mike Wallace, University of Washington; Prof. Justin Wettstein, Oregon State University; Prof. Dave Thompson, Colorado State University

• We explore the leading mode of tropospheric variability associated with atmospheric response to eddy momentum flux forcing.

Atmospheric Persistence

Collaborators: Prof. Dave Thompson, Colorado State University

• We investigate the physcial mechanism that accounts for persistence of atmospheric temperature anomalies.
