Hurricanes 2010

Since the last hurricane related post, some news has occurred on the hurricanes front. Nature Geosciences article by Knutson et al. (2010) discussing the linkages between tropical cyclones and climate change / global warming — as an update to the IPCC AR4 statements Whether the characteristics of tropical cyclones have changed or will change in […]

Kerry Emanuel Boston Globe Opinion: Climate Changes Are Proven Fact

Dr. Kerry Emanuel from MIT wades into the climate change debate with an opinion piece in the Boston Globe.  Dr. Emanuel has not been particularly outspoken on the climate change topic but has from time to time participated in debates and forums that have provided an opportunity to opine.  On the heels of Hurricane Katrina, […]

Hurricane watch 2009: scraping the bottom

With the North Atlantic hurricane season still waiting for a named storm, and the rest of the globe cyclonically challenged during the past several months, it is a good time to catch up on the research end of things. In terms of papers during the past 6-8 months, the amount of tropical cyclone and climate […]

Baby whirls: improved detection of marginal tropical storms

With the North Atlantic hurricane season officially starting in a couple weeks (June 1), but possibly getting a head start with a developing low-pressure system in the Bahamas, considerable attention will be paid by the media to each and every storm that gets a name. In the North Atlantic, a name is granted to a […]

EPA, CCSP and Hurricanes

(Perhaps I’ll review this […]

Great Depression! Global hurricane activity reaches new lows.

Post by Ryan N. Maue, Florida State University COAPS Global hurricane activity has decreased to the lowest level in 30 years. Figure: Global 24-month running sum time-series of Accumulated Cyclone Energy updated through April 21, 2009. Very important: global hurricane activity includes the 80-90 tropical cyclones that develop around the world during a given calendar […]

Atlantic Hurricane Season 2008 Withers on the Vine

The North Atlantic hurricane season has nearly come to an end. As November progresses, the chance of another storm developing becomes smaller. Climatology (last 60 years) tells us that roughly 4 in 10 years see a November storm formation including 4 in 2005 (Beta, Gamma, Delta, Epsilon), Hurricane Michelle (2001), Hurricane Lenny (1999), and Hurricane […]

Hurricane Gustav

Sept 9: Updated to follow Hurricane Ike, and possible US impacts in the next 4-5 days The North Atlantic tropics are becoming very active as the calendar approaches the climatological peak of the season (September 11). With high sea-surface temperatures and generally favorable atmospheric conditions (i.e. low vertical shear), every circulation or puff of convection […]

Emanuel 2008:Global warming and hurricanes

A new peer-reviewed paper has been published in an American Meteorology Society journal that raises many more questions on the linkages between hurricane activity and global warming. Eric Berger at the Houston Chronicle (SciGuy) did the leg-work and is the first (and only) mainstream media outlet to report the findings of Emanuel et al. (2008) […]
