An average of the speculation of range of WAGs by fund-starved researchers.
In this day and age, there simply isn’t enough money or time in that industry to justify long term legitimate work or ‘research’....just more rehashed speculative crap about rehashed speculative, unsupported ‘data’ that are questionable at best. The end goal STILL being, “The Quest for the Inexhaustible Funds.”
Well, actually as we begin to fly in smaller planes due to the need to become more fuel efficient to save the planet, felt turbulence will probably increase as smaller planes are affected more than larger ones. Now, a 150% increase, that is something. Maybe we should build a fleet of planes that fly above the weather, say at 60K feet? With the decrease in the size of the ozone hole (remember that scare from 30 years ago) it should be safer then flying through this increase in severe turbulence, turbulence which by its very description is so dangerous that the FAA will not allow flying through it.
