I've debated on whether or not I should weigh in on the Hurricane Sandy/Climate Change/Global Warming debate circling the blog sphere. Even saying the words "debate" in the context of Global Warming or Climate Change is tantamount to treason and a reason to fight for some. Others would argue that I've left the AGW door wide open for a huge ransack.
So rather than take a stance either way, I want to list the components that went into the development of this storm in no particular order and leave it to you to allocate what percentage of influence each component contributed to the evolution of Hurricane Sandy and the subsequent hybrid. Is it the natural cycles or the Anthropogenic drivers or a blend of both? One more than the other,etc.
1. Strong sub tropical jet stream along the east coast moving southwest to northeast
2. Very strong polar jet merging with the sub tropical jet
3. Greenland Block (High pressure over the North Atlantic/southern Greenland)
4. Upper level trough became negatively tilted (that is the trough was oriented NW to SE) established by the Greenland Block
5. Sea Level increase along the east coast
6. Warmer Atlantic Ocean overall - Atlantic Multidecadal Oscillation cycle
7. Above normal water temperatures in the Atlantic right off of the east coast
8. Arctic Ice Loss
Am I missing any?
