Since March 2003 I am a Postdoc in the Advanced Study Program at the National Center for Atmospheric Research. I received my PhD in 2003 from the Department of Meteorology at the University of Bonn, Germany.
THESIS WORK
My thesis is on Detection and Stochastic Modeling of Nonlinear Signatures in the Geopotential height Field of an AGCM . I developed a nonlinear stochastic model with multiplicative noise for atmospheric low-frequency variability. Further work includes the detection of low-dimensional phase spaces that capture the nonlinear signal in the velocities and probability density function of the projected geopotential height field.
CURRENT WORK
  • Development of stochastic parameterizations for simple models.
    RESEARCH INTERESTS
  • Nonlinear and linear stochastic processes with multiplicative/additive noise.
  • Stochastic parameterization of subgrid-scale processes.
  • On which timescale can the dynamical evolution of a deterministic system be approximated by a stochastic process?
  • State-dependent prediction and predictability.
  • Detection and optimal representation of nonlinear signatures.
  • Optimal representation of atmospheric dynamics in truncated models.
  • Dynamical interpretation of nonlinear signatures in the geopotential height field.
