Alas, supercomputers are not accurate predictors



THE TWO TOP hurricane predictors in the world are coming clean about the NON-ablility to accurately predict even the same season's coming hurricane activity ... let alone 50 years from now.

OTTAWA — Two top U.S. hurricane forecasters, famous across Deep South hurricane country, are quitting the practice of making a seasonal forecast in December because it doesn’t work.

William Gray and Phil Klotzbach say a look back shows their past 20 years of forecasts had no predictive value.

The two scientists from Colorado State University will still discuss different probabilities of hurricane seasons in December. But the shift signals how far humans are, even with supercomputers, from truly knowing what our weather will do in the long run.

Colorado State has been known for decades for forecasts of how many named storms and hurricanes can be expected each official hurricane season (which runs from June to November.)

Last week, the pair made this announcement:

“We are discontinuing our early December quantitative hurricane forecast for the next year … Our early December Atlantic basin seasonal hurricane forecasts of the last 20 years have not shown real-time forecast skill even though the hindcast studies on which they were based had considerable skill.”

The two will still make the traditional forecasts closer to hurricane season.


My hat's off to them for stepping up to the honesty plate. We will see if more follow the truth ... instead of following the dollar.
