Critical Questions

1. What does the pattern of 850-hPa low-level wind anomalies show? Where are the easterly/westerly wind anomalies respectively?

2. How is the pattern of anomalous Outgoing Longwave Radiation (OLR) organized? Is there evidence of eastward propagation of these OLR anomalies?

3. What does the spatial map of velocity potential anomalies indicate?

4. What is the current amplitude and phase of the Wheeler-Hendon (WH) MJO index? How has it changed during the last 1-2 weeks?

5. What does the GEFS WH MJO index forecast indicate? What is the forecast confidence?

6. What do the dynamical and statistical OLR anomaly forecasts depict about the spatial distribution of convection?

7. Given the forecast of the MJO, what do composites say about potential tropical impacts?

8. What does the MJO weekly update state about the future evolution of the MJO?

9. What does the MJO weekly update state about impacts across the Tropics and US during the next 1-2 weeks?
