Recurring Rossby Wave Train
(Consonant Chaos: Experimental. Projecting long range weather and short term climate based on the Recurring Rossby Wave Train)

This website's primary purpose is to be a home for the Recurring Rossby Wave Train forecast and analysis mappings offered by myself (Josh Herman) and various projects I am developing related to recurring atmospheric states. These mappings do not represent the forecasts of any government office. Please visit the US Dept of Commerce NOAA/NWS/NCEP Weather Prediction Center for official weather forecast and analysis information.

 Framework of the Recurring Rossby Wave Train; Establish numerical output of recurring atmospheric states. Further explore the interrelated nature of planetary and synoptic waves via statistical modeling. Reflect this temporal and spatial behavior of Intraseasonal Oscillation to weather patterns based on the empirical data.

I have been tracking recurring atmospheric states intimately since 2010. My past work is available. RRWT archived forecasts are available. For more detail concerning this study and a gateway for more research, please start with
Chaos Theory and Its Applications to the Atmosphere.
