Research Interests

My interest is in observational studies of the mean conditions and variations of the atmosphere, ocean, and biosphere, including El Niño, the El Niño / Southern Oscillation (ENSO), and how climate affects fish.

Current Research Projects

  • Characterization of the upwelling-producing winds along the west coast of North America, both in the historical record and in models of future climate.
  • Documenting the forecast skill of October-November-December Pacific Northwest precipitation.
  • Ocean temperature anomalies east and south of Hawaii have been shown to precede ENSO fluctuations by about a year. This is referred to as the "seasonal footprint" mechanism. I am documenting a Southern Hemisphere analog to this phenomenon.
