Let's begin with last years (8/1/13-7/31/14) dominant components.

Difficult to imagine that ~57 didn't show up much. The chart below shows how using the dominant harmonic can prove to be solid guidance as we know the short-term, mid-term, and long-term will all have their days in the sun so to speak.

Below is the average of each component 10-20, 30-60, and 60-90 days.

What about this coming season? 17-18 days are tops this morning (8/31/14). 74-76 days are right behind. However, through August, 58-60 days has been the most dominant. Likely to swerve in the coming weeks.

With the long-term likely to cycle negative soon, the short-term should recover and produce the new patterns for the upcoming season. Discussing this with some others, I agree we can use the 74-76 to find the LRC and confirm with the short-term using standing wave harmonics.

But, I haven't looked at maps, anyone seeing this 58-60 or 74-76 day connection? Some suggest taking the current short-term from the current long-term for this years LRC duration. Give or take a day. smile.gif
