Current Research

I am currently working on evaluating the Unified Forecast System (UFS) prototypes on S2S time scales for their tropical variability. I'm looking at tropical diagnostics of skill in predicting large scale convectively coupled equatorial waves, the MJO and teleconnections to the extra-tropics.

The CSF distribution is the CSF probability density distribution given as percentage of total samples, whereas the conditional precipitation rates are precipitation averages for each CSF bin.

Distribution of CSF and conditional precipitation
