Sucker Punched Very Slickly

Filed under: Politics,Science — PolitiCalypso @ 10:27 am

As any writer of Southern literature would tell you, the central Gulf Coast is a tragic place. It is the final destination of many terrible hurricanes, including Katrina, Ivan, Camille, Betsy, Audrey, Andrew, and a plethora of unnamed hurricanes in the early 20th century that caused devastation equivalent to that of their named brethren. It has been and continues to be the laboratory for the experiments of the U.S. Corps of Engineers, which incidentally are at least peripherally to blame for the damage from Katrina in New Orleans. The Gulf of Mexico itself has had a biological “dead zone” for several years from chemical runoff in the Mississippi River. Coastal wildlife, too, is constantly under threat, with various birds and seashore creatures perennially on the endangered species list and the coastal wetlands under assault. The threat of inundation from sea level rises from global warming looms in the future.

And yet, the coast has managed to maintain a certain charm. Visiting some areas is like living in a Jimmy Buffett song. Taking a tour of historical sites—those that have survived the onslaught of hurricanes—brings one into a bygone era of simplicity, a certain kind of elegance (even for the more rustic historical sites), and closeness to nature. Visiting one of the many wildlife sanctuaries on this coast and observing the unique plants and animals that live there can make an environmentalist out of anyone but the most hardened plutocrats, even though (or especially since?) such jaunts are darkened by the inevitable signs indicating that some creature is critically endangered. And anyone who has ever taken a walk on the white beaches of Alabama or far western Florida at night can attest to the subtropical marine beauty of the Gulf. The coast is its own travel advertisement.

Were it not for the hurricanes, and the fact that they have a much higher tendency to make landfall at devastating intensities on the Gulf Coast (and southeast Florida) than the subtropical Atlantic coast, I would consider living as close to the shore as I could manage.

But once again, the Gulf Coast has been sucker punched.

I’m not going to go into depth about the science of this oil spill or the technological requirements of damage control. Mechanical engineering and petroleum engineering are not my specialties, nor have I read much of anything about them in my life, and unlike many bloggers, I’m not inclined to make an ignorant-sounding fool out of myself by pretending that I know something about a topic when all I’ve done is to read about it on the news and maybe check a Wiki article or two. Not to mention that I, quite frankly, no longer believe one word coming out of the mouths of anyone protecting BP, the various supporting industries such as Halliburton (though I haven’t believed them in eight years), or the White House. You simply cannot believe any source except scientists if it has an agenda to protect that relates to the topic at hand, and sometimes even certain scientists lose sight of the fact that they are supposed to accept the truth even if it is not what they wanted. This is going to be an absolute disaster; bits of information are trickling out now to indicate just how thoroughly these entities tried to lie to the American public about the scope of this, and like the spill itself, the trickles are only going to get worse.

It is incredibly hubristic to imagine that one could prevent the truth from getting out about something as large-scale and catastrophic as this, but power knows no boundaries in its arrogance. Though history is littered with the figurative corpses of former power-brokers who thought they could get away with massive lies, each new set thinks it is invincible until put to the test. BP’s reputation is shot. And the White House may well try to do damage control by implementing a temporary ban on offshore drilling, but that does not erase the fact that the president broke a major campaign promise by getting out there and supporting this type of thing in the first place and then sent a spokesman to say that the spill didn’t change his mind. (The time to act like George W. Bush is when you are trying to get a piece of legislation passed in a non-watered-down form, not when you have just witnessed the American Gulf Coast experience a disaster on your watch that could have been either mitigated or entirely prevented. Heck of a job.) People will pay a price for dishonesty.

As for the pathetic, deranged “progressive” South-haters who will say in so many words that the people of the Southern coast (we’ll ignore the innocent wildlife for now) got what they deserved for voting for politicians that support offshore drilling, well, to dignify this bigoted bile with a response is beneath me.

The only remotely positive outcome I can think of is that of disaster-as-catalyst. It is far past time for the world’s economy to get away from fossil fuels. If I believed that God destroyed innocents on Earth in order to teach the survivors a lesson, I would say that the oil spill and the recent tragic coal mining disaster are one heck of a message. As it is, I think it’s just a terrible coincidence. Still, we can always choose to take a lesson from it even if the events themselves have no greater meaning. We are in the 21st century. We should not have our civilization so utterly dependent on the compressed or liquefied remains of prehistoric life forms. Do I think that this will serve as a catalyst to finally get away from the intravenous drip of oil and the crack pipe of coal? Not really. But then, I’m a cynic and a pessimist. I’d be delighted to be proven wrong, both about the impact of the spill and about our future.

I do love the Gulf Coast, after all.

Getting Ready: An Early Preview of the 2010 Hurricane Season

Filed under: Weather — PolitiCalypso @ 10:28 am

From the point of view of a snow lover, it was an excellent winter. But that is now long over for those of us in the Eastern United States. Many areas have already hit 90°F! Here in MS we have not, but I anticipate that some spot in the Gulf Coast states will reach this wretched milestone early in May.

Before I get to the topic about a future event, I feel compelled to talk about one closer to the present. Severe weather season is upon us, though it is off to a slow start. The Southeastern states are arguably past the springtime peak and seem to have gotten off quite light, but we must not forget that it is the months of May and June when so many major tornado disasters have occurred. Jarrell, TX… Moore, OK… the May 2003 outbreak sequence… Greensburg, KS… Parkersburg, IA… those are all F5 or EF5 events except for 2003 (and even it had a tornado that was considered by some to have been underrated as F4). The list goes on, and it does not require an EF5 tornado to do massive, tragic damage. But it is very difficult to forecast severe weather more than a few days in advance, let alone a month or more.

Hurricane season is a different matter, and it is quite possible to make long-range forecasts about the overall activity level of a particular season, especially now that we are merely a month and a half away from the beginning of the Atlantic season. 2010′s hurricane season is not, I believe, going to be anything at all like 2009′s.

The strong El Nino event that gave the Eastern U.S. such a cold and snowy winter (and killed off much Atlantic hurricane activity) is fading fast. The majority of ENSO models predict a return to ENSO-neutral conditions by the June-July-August period (link: PDF).

However, El Nino has left its mark. As is typical following a significant El Nino event, sea surface temperatures in the eastern Atlantic are well above average, and in fact, the anomalies for this year are greater than the anomalies in April of 2005, a year that had record heat across the ocean. In the far eastern part of the ocean, there are areas that are already at 30°C.

If this continues and shear decreases as expected, this year may be quite good for long-tracked Cape Verde systems. Indeed, these temperatures are apparently a record in terms of warmth.

The Gulf of Mexico is below average, but this is because of the cold winter. With surface temperatures reaching into the upper 70s and low 80s in the Gulf states for the foreseeable future, and little cloudiness to moderate the effect, it’s likely that this body of water will warm up. Indeed, observing the sea surface temperature anomaly maps for the past few weeks indicates that this warmup is occurring already.

A limiting factor at present may be wind shear, which is above the climatological average:


(Link takes you to the current shear map on NOAA.)

This will continue to be a limiting factor for cyclone development if it persists into the early season. However, as the El Nino fades, shear should decrease. Indeed, the current above-average level of wind shear may only be a temporary event, as overall it has been below average for much of the past several months:


(Link takes you to the current shear graph on NOAA.)

The Bermuda High, an area of high pressure that extends to the western Atlantic, is not yet established. The location of this feature will be important to watch, as it determines whether long-tracked Cape Verde hurricanes tend to strike land—and what landmasses that they strike—or recurve to sea. The farther west it goes, the more likely that such hurricanes will hit a coastline, but too far west and storms tend to be steered south of the United States, as was the case in 2007.

In short: Sea surface temperatures are likely not going to be a problem in 2010. I think the features to watch, here in the pre-season, will be the evolution of ENSO, the location of the Bermuda High, the warmup of the Gulf and far western Atlantic near the Bahamas, and the levels of wind shear as compared to climatology. If the ENSO level decreases to neutral by the peak of the season and shear decreases to the climatological average (and these two factors are very intimately connected, I should note), but sea surface temperatures continue to remain high, I fully expect to see some beasts brewed up and for “Category 5″ to make a reappearance in this basin for the first time since 2007.

Unless the ENSO prediction models are mostly wrong, the Atlantic coasts are not going to get off light this year. It’s impossible yet to determine what areas are likely to be targeted, since we do not know how far west that the Bermuda High will set up, but at present I would go out on a limb and say that somebody is in for a bad year. It’s time to start getting ready.
