Hurricane Forecasters, Blow It, Again

October 7, 2010

Despite dire predictions, naming every cloud puff, the public still sees the hurricane for what it is, a bust. Now how would they have known that? Simple just look at the strengthening El Nino and the world ocean sea surface temperatures. It’s getting cold out there. Satellites make truth easy — Tropical cyclones draw energy from warm sea water, and when it gets cold, hurricanes shiver and die off.

The 2010 Atlantic hurricane season has been very active in the number of storms but is likely to go down as a non-event for most people in the United States, which has so far dodged a major landfall, the top official U.S. hurricane forecaster said on Tuesday.

Before the June 1-Nov. 30 season got under way, residents of hurricane danger zones were warned by many forecasters they faced a very high probability of a major hurricane making landfall along the U.S. coastline.

That has not happened and with the most active part of the season winding down in the next two weeks or so, the chances of a major impact on the U.S. mainland or on energy interests in the Gulf of Mexico are ebbing.


QuikSCAT Antenna Fails: Likely Dead For Good

April 11, 2010

QuikSCAT is no longer in operation, according to NASA.  The satellite’s scatterometer antenna stopped spinning.  If the antenna cannot be restarted it will no longer be capable of taking sea surface measurements as it had been in the past.

The weather community is still debating the significance of QuikSCAT and a replacement satellite.

It’s unclear the true effects the loss of QuikSCAT will have on tropical cyclone forecasting.  But, one thing is sure: you can never have too many weapons in your forecasting arsenal.

NASA will continue to try and restart the antenna using various techniques. Considering the satellite was only supposed to last a few years but has been operational for 10, I suppose we should be thankful we got out of it what we could.


“Tiny Tims” — Stating The Obvious

August 24, 2009

‘Tiny Tims’ are a nickname for Hurricanes-Tropical storms which are well you know, tiny, and would probably have escaped detection before satellites were watching.

One thing for sure, it’s not global warming, man caused or otherwise, causing the higher numbers for named storms … But it might be global cooling lowering the real numbers. The last hurricane, ‘Bill’ was run off from the USA coastline by a cold front, that eventually stretched from New England to Tampa Florida. And it’s still August!!!

Keeping the hurricane record pure, is not an easy task. The very latest observation satellites of the last years are of such capability that they swamp out the old ‘ship observations’, way back when

For instance, when the 1900 Galveston hurricane hit Galveston Texas, as many as 12,000 people were killed, the warning that there was even a hurricane coming ashore, was measured in hours — The hurricane warning system was very poor back then. This causes a problem with record keeping, when trying to equate storms over a hundred years, storm trends and predictions can be way off. Comparing modern hurricane-tropical storm detection and the old way, is difficult, if not near impossible, making chart comparisons very iffy(same can be said about tornadoes).

Now a NOAA led team is stating the obvious:

A NOAA-led team of scientists has found that the apparent increase in the number of tropical storms and hurricanes since the late 19th and early 20th centuries is likely attributable to improvements in observational tools and analysis techniques that better detect short-lived storms.

Short-lived Tropical Storm Chantal forms 210 miles south of Halifax, Nova Scotia on July 31, 2007.

The new study, reported in the online edition of the American Meteorological Society’s peer-reviewed Journal of Climate, shows that short-lived tropical storms and hurricanes, defined as lasting two days or less, have increased from less than one per year to about five per year from 1878 to 2008.

“The recent jump in the number of short-lived systems is likely a consequence of improvements in observational tools and analysis techniques,” said Chris Landsea, science and operations officer at NOAA’s National Hurricane Center in Miami, and lead author on the study. “The team is not aware of any natural variability or greenhouse warming-induced climate change that would affect the short-lived tropical storms exclusively.”

Hurricanes 2009, Through July

July 30, 2009

Ryan Maue of Florida State University writes in comments:

Global (Northern Hemisphere) tropical cyclone ACE for the months May – June – July is the lowest in at least the past 30-years or more.

I, for one, am not surprised.  Continued inactivity should persist for the next few weeks until the atmosphere catches up with the radiative warming of the tropical oceans due to the season called summer.

2007 was a dud.   2008 was saved from being a record year by 2007.  2009 is behind the pace of both years.  Amazing how natural variability affects tropical cyclone formation, tracks, and intensity.  Who would have thought?

Ryan’s Tropical web page at Florida State University has this graph that shows accumulated cyclone energy (ACE) :

2009 Hurricane Forecast

May 22, 2009

After totally blowing the forecasts since 2005, this time the forecasters  step out with a word of caution. Basically, NOAA is saying we don’t have a clue. They can’t really stick it to the global warming hoaxers at this critical time, the charge is on for more taxes, so they punt. Hurricane prediction is nothing more than a statistical guessing game, with a touch of experience. No one can predict the future, we just aren’t that advanced.

So Far, So Good

August 7, 2006

The 2006 hurricane season has been good. No storms. Hope it lasts.
