Document Summary
A prediction from a computer model of global warming. Increased shear over the gulf of mexico would act to weaken hurricanes. Would offset some of the increase in strength due to increased temperatu. Also the atmosphere tends to stabilize when there"s more moisture. Had to use alpha, beta, gamma, delta, epsilon and zeta. But we know better to say that one season is due to global warming. Plus only 10% of the worlds hurricanes occur in the atlantic. These storms would be category 6 or 7 if they existed. Recent study claims that the strongest hurricanes have increased. "power dissipation index": better measure of strength that combines frequency, duration. Pdi in the atlantic in highly correlated with atlantic ocean temperatures. Hurricanes will continue to strengthen with global warming. Debate was rather heated for a while ratures ncy, intensity and. Fundamental problem is that the observed record is short, and hurricanes are re events.
