Multivariate PNA (Includes MJO indices)
- This is a relatively new index that has been proposed to help determine which MJO events will impact North America. Think of it as a correlation index of sorts. Included in the index are the NA 200 hPa streamfunctions, 850 winds, and OLR for each phase.
- You want the opposite MVP based on the phase. For example, phase 4 of the MJO which is known to be warmer in the E. US, will be lessened if the MVP is greater than -0.75. And vice versa, if the phase 4 MJO will have stronger impacts for E. US warmth, the MVP will be <-0.75.
- Phase 7-8 of the MJO, which contributes to cooler weather in the E. US, will be enhanced if the MVP >+0.75. It will be lessened the further negative the MVP is. So they are essentially opposites.

The CPC website contains SST forecasts from CFS, CMC, NCAR, NASA, IMME. It also has precipitation, 2m temperature, and ensemble probabilities. Very nice resource!
