Perhaps you are aware that the Saffir-Simpson Scale is how we measure Major storms like Typhoons, Cyclones, and Hurricanes. The scale has specific wind speeds which indication such things as Tropical Storms from Tropical Depressions, and then from there to Hurricanes by category of intensity.
Category One starts at 74 mph and goes to 95 mph for instance. Category two is 96-110 mph, category three is 111-130 mph and realize these are "sustained wind speeds" - Category 4 winds are at 131-155 mph and the top of the scale is category five at 156+ mph sustained winds.
Now then, you can see the problem when your wind speeds are getting above 190 mph, as there is no category to warn people that it's an "oh my god, motherload of destruction category, leaving nothing in its wake!" You see, we've been having too many "off-the-chart" storms with unheard of low pressure areas and wind speed that the Saffir Simpson Scale for Cyclones, Typhoons, and Hurricanes is inadequate now.
The recent Cyclone in Australia, "Yasi" was 186-190 miles per hour, which means theoretically it was touching what might be considered a CAT 7 storm, and definitely a CAT 6 - that is if there were such categories, but there are not because the winds stop at CAT 5.
In 2005 we had three Hurricanes here in the our own sphere of influence; Rita, Wilma, and Katrina which at one point each far exceeded CAT 5 and well into what should have been CAT 6. Since then there have been three Typhoons which also should have been CAT 6 in the Pacific. Why is this?
Well, I am quite sure that Al Gore would say it was due to Global Warming, but I suspect most of this is because we have better measurement devices now and track these Super Storms during their entire growth and dissipation cycles.
Another possibility for super storms of this Earth's magnitude is shifting and evolving faster or differently than before causing it to weaken in places and assist in creating larger storms. There is at least some decent empirical data which would imply this is occurring, and we know from the geological record that it does occur from time to time.
A scarier scenario might be we are close to a pole flipping even meaning that we could be entering the beginnings of an ice age. These are plus or minus 11,500 to 12,000 year cycles. Nevertheless, now that we know we MUST stop delaying the realities of the force of these mega-super-storms and revise the category, because clearly the Saffir Simpson chart is lacking with our current knowledge of the weather. Please consider all this.
