The East Asia Rule (aka Typhoon Rule) Verifies the Bering Sea Rule Verifies the Recurring Rossby Wave Train Pattern

A date in time. Let's choose December 2nd. (Observed Map)

East Asia Rule (aka Typhoon Rule)


Verifies the Bering Sea Rule (BSR)


Verifies the Recurring Rossby Wave Train (RRWT)


Individual RRWT maps
20150803


20150912


20151017


The individual RRWT patterns are based on the 15 day mode frequency, 12/2 ~45 is 10/17 ~36 is 09/12 ~41 is 08/03.

OSNW3|WxClimate Knowledge Base: 2015-16 Current Performance and Members Used in the Model Ensemble

The OSNW3|WxClimate daily forecast Trends began forecasting and accumulating verification data on October 1, 2015. I often look at them to analyze how the forecasts are performing. On November 13, 2015 I selected the MaxT Trend for Green Bay, WI.

October 2015 MaxT Trend for Green Bay, WI


November 2015 MaxT Trend for Green Bay, WI


A quick glance shows that some individual Members out performed the Ensemble, the Mean of all Members. I expect this to happen. Also, the early November miss could be blamed on the removal of the "Full Blend" analog for the 2015-16 testing. I would have to perform a deeper analysis to prove this however. It could just be a miss, and that is OK.

Daily Frequency Used To Project Weather Conditions


The Members are listed below.

M1 = 'Regional+' 15 Day Correlation Mode
M2 = Climate 'Region 6' Top Correlation
M3 = 'CONUS' Top Correlation

Consider this an attempt at Group Velocity. The 'Regional+' bucket is top R of individual stations. My reasoning to use this parameter is to capture the high frequency carrier wave based on standing wave notation, as I ignore all frequencies lower than 30. The 'Region 6' bucket is top R of all stations in the particular climate region. The 'CONUS' bucket is top R of all contiguous US stations. My reasoning to use these parameters is to capture the low frequency amplitude modulation. Molded into an envelope I attempt to project long-term weather conditions based on the amplitude of pattern correlation.

As always this is a work in progress. If there are any questions, comments, or suggestions on the material presented please let me know. Click on the images for a larger view. Thanks for reading!

Western Great Lakes Region 2015-16 Winter Forecast Snapshot (DJFM)

The Framework: Utilize NOAA/ESRL Radiosonde Database to analyze large-scale upper atmosphere patterns in standing wave notation. Described specifically to harmonics, reflecting the temporal/transient behavior of the frequency wavelengths in correlation and relating Intraseasonal Oscillation to Mid-Latitude recurring weather patterns. The Goal: Forecast skill of upper-air and surface weather trends. The Test: Recurring Rossby Wave Train.

As of November 10, 2015 two dominant frequencies of correlation are identifiable. A low 30 and mid 40 day wavelength. Simply put, my model projects based on the weather pattern correlation standing wave behavior. Forecasts and analyses of this behavior can be found here. If more indepth information is desired I often Tweet and post on the AccuWx Forums.
