(short visit to Japan)

• Climate Prediction
  • ENSO variability and prediction (in collaboration with Prof. B. Wang)
• Apply the Ozaki's scheme to numerical prediction model (In collaboration with Prof. N. Ozaki and Dr. Zheng Xiaogu)
• Conceptual climate model

• Monthly and seasonal predictions of surface air temperatures and precipitations. (with R. Vaudard, LMD (National Center for Scientific Research), Paris; H. Van den Dool, CPC, NOAA, and G. Plaut, Nice, France)
• low-frequency variabilities in phase space based on observational data and model output (with G. Brunet, RPN, Canada).
• Intercomparison of methodology such as the space-time extended EOF analysis, the classical EOF analysis and its rotation, singular value decomposition (SVD) and canonical correlation analysis (CCA).

• Analysis of the atmospheric variability associated with the north Atlantic storm tracks based on observational and GCM data (With K. Fraedrich, in close collaboration with the research Group headed by I. James, Department of Meteorology, University of Reading).
• Analysis of the observed low frequency fluctuations in tropical area (With K. Fraedrich, J. Mcbride, Sydney, Australia, and Bill Frank, USA).
• Variability of Marian atmosphere based on observation and GCM (in collaboration with Reading group headed by I. James).

• Developing methodology for extracting the correlation dimension of a system from measured signals with special emphasis on dealing with noisy and short data sets.
• A study on the middle latitude atmospheric fluctuations with respect to space- time coherent structures in terms of phase-space approach. (with K. Fraedrich).
• Studying the variability of the tropical stratospheric quasi-biennial oscillation (QBO) (with S. Pawson and K. Labitzke, Berlin, and K. Fraedrich).
• Analysis of the low frequency-fluctuations from observations and GCM outputs via application of nonlinear theory. (with K. Fraedrich, P. James and I. James, Reading, UK).
