Research Interests

My research is directed towards understanding the Earth's climate variability. I am particularly interested in studying how the interactions between processes acting on small (synoptic) scales with larger-scale (regional-to-global) processes affect the overall climate behavior. Examples of the problems I am dealing with include:

  • analysis and attribution of the Earth's surface temperature trends,
  • decadal climate variability in the tropical Pacific and Southern Ocean,
  • low-frequency, intraseasonal, variability of atmospheric jet streams,

among others. I approach these problems via a combination of statistical data analyses and dynamical studies that employ a hierarchy of climate models.
