If as I suspect there is a vicious cycle of tornado cells approaching North America, it would explain the lack of a system that usually forms in harmony with the appearance of strong (and even not so strong) tropical storms.

The same thing happened in January for the two massive storms either side of Australia in the middle of that month (Ian and Colin http://weather.unisys.com/hurricane/...2014/index.php and http://weather.unisys.com/hurricane/...2014/index.php)

At least I have mentioned in previous chapters of the Weatherlawyer Saga that the North American tornado season is the reason why the North Atlantic hurricane season starts so much later than thee other northern hemisphere seasons.

Not that there is really any such thing as a season.just the winds invoked reach the rotational velocities required by convention for classical classification.
Ooh! And it makes me wonder about climbing the stairways of heaven.
What exactly is the classification when we can't study the rotational behaviour of winds just off the surface a few hundreds of feet. Satellite receptors will have to get orders of magnitude more powerful before we can do that with them.
