West tracking catagory 5 in September with QBO having flipped about 2
months. Note how all the storms do well once they start tracking
east after right turning.
Normal season. Note how the catagory 4 storm tracked in formation
with the catagory 5 storm above.

With QBO so negative all year the season was way down, and only
intense when moving east above the ITCZ.
Anemic season with no storm over catagory 1. Again, the QBO as
negative really is hard on west moving storms. This is what
Fleming's right hand rule is about and induction. The orientation of
the EMF flips and so induction does to--that is why the winds flip.
At the same time, impedance is impacted on the surface and the storms
couple poorly moving west.
In the west Pacific, the number of storms is down about 10 with the
QBO like this.
This is also a winter of El Nino SSTs in the Pacific, which seems to
suppress tropical storm activities. See:
However, the SOI index runs back and forth during this time, which is
sufficient IMHO to juice tropical storms in all the basins from the

Now we flip back to positive during the heart of the hurricane
Hurricane CAMILLE (14-22 AUG) and Hurricane DEBBIE (14-25 AUG) are
storms that are moving west in tandom, again, essentially along the
ITCZ, with a little of north movement that is consistant with
thermodynamics pushing toward colder and less organized air, BUT the
movement is essentially west in conjunction with the QBO. Camille is
one of the all time great storms.
Very little going on in the EPAC with so much activity in the
If you look at the SOI index from Daly's site, interestingly, a
largely negative SOI occurs in 1969 FOLLOWING the 1968-9 El Nino.
This is also indicative of an extreme electrical condition, IMHO, the
SOI running contra to ENSO. Such a negative SOI suppresses EPAC
Notice the almost straight west movement along the ITCZ of super
typhoon 11. This is later in the season, and, again, in the context
of a positive QBO.

Now we are back to a negative QBO again during the peak of the
With QBO so negative all year the season was way down, you would
expect the only the intense storms would occur when moving east above
the ITCZ. With 9 and 10 this is true, but Camille was such an
intense storm in the EGOM that it change the GOM environment, IMHO,
such that WGOM storms are favored, which is what occurred. By this
time, the SOI is back to its back and forth ways, which tends to
power storms in the oceans.
A little more active in the EPAC, which is what we might expect with
a flipping SOI.
In the west Pacific, the number of storms is way up with 4 super
After this activity in the West and East Pacific, a La Nina forms
