Tropical Storm Bertha
July 03, 2008 5:01 PM
It's the second named storm of the year, and already it's set a record. As Jeff Masters of the Wunderground weather site puts it, Bertha, at 25 degress west longitude, "is the farthest east a tropical storm has ever formed in the Atlantic so early in the season. It is also the farthest east a tropical storm has formed in the month of July." Take a look at his post HERE, and as you'll note in the GOES-12 satellite image, it's unusually close to the coast of Africa, heading westward.
There's been considerable research in recent years, showing that tropical storms and hurricanes really have their roots, not out in the Atlantic, but all the way over in the mountains of northeastern Africa -- near the Red Sea. Moisture from there, tumbling over the mountains and then picking up heat as it heads westward over the Sahara -- that's the genesis of many storms.
The good news is that this one is small, and far, and may not come at all close to the U.S. Take a look HERE at the forecast path from the National Hurricane Center; the five-day track shows Bertha, if it remains a storm, turning north in the mid-Atlantic. (The hurricane center forecasters warn us not to use the five-day track to make plans, but they're still pretty good at what they do.)
On that note, we wish you fair winds for the holiday.

The eastward fromation may have much to do with the climate shift (not AGW). The magnetic pole has moved towards Siberia, volcanic and techtonic activity has increased under the Arctic and Greenland, the middle and eastern portions of N.A. is cooler and wetter while europe has remained hotter. The South Atlantic Magnetic Anomaly is active. The increased heat forms these storms so it makes sense that it formed farther east.

Quietman - how do you think the magnetic and tectonic and volcanic activity would be affecting this? I'm very doubtful that has anything to do with it (at least in the short term; obviously, continental drift and long-term geologic CO2 emission rate changes will affect climate, but nothing like that would be significant over such a short time as a few hundred years; volcanic eruptions of course have a short term cooling effect, but ... what eruptions and tectonic activity are you refering to? High latitude eruptions have a less potent cooling effect.)

Quietman:
In my thirty-five years in geophysics, that is the oddest admixture of nonsense I've ever seen written in one paragraph.It is, however, quite original. No geophysicist, geologist, or any other professional would dare blow that much smoke all at once. They'd never work again. Congratulations.

No, I happen to know that Quietman is a very kind and thoughtful man. That doesn't make him right, of course, but he is sincere. But he has decided that the AGW hypothesis is wrong and no one is going to budge him.

Why mention anything about this storm setting records? This serves as fuel for oil speculators. Do we need $10 gas by next week?

All I know is the last Bertha turned into a hurricane and hit us here in NC. It wasn't too bad but it was followed that year by several others including Fran that did several million in damage. The only thing I want to hear about Bertha is that she is heading the other way.

Oh boy! Here we go! For those not interested this is only the beginning besides humanities rising carbon footprint a weak geomagnetic field due to magnetic pole reversal and a star in the prime of it's life burning hotter than ever, this weather is just getting started! The Midwest is a disaster with off season tornado strikes and it makes sense that a Hurricane season of unprecedented proportions could follow. The signs for such are indeed promising! Those who don't care will after some of their relatives get hit, let me assure you that likelihood looks pretty for real!

Everything I said I can quote a reference for, albeit science articles, not peer reviewed papers. Just what part have you not heard of before?
Posted by: Quietman | Jul 4, 2008 3:39:15 AM
Jock
Thanks for the kind words.
Posted by: Quietman | Jul 4, 2008 3:40:38 AM
Correction - I can quote a reference article for everything except South Atlantic Magnetic Anomaly, that I have only heard in a forum.

P.S. I'm retired on disability - I will never work again anyway so why not speak my mind. That is an issue with AGW, if you take a position youre stuck with it because of political pressure. Hansen (NASA) can't afford to change his mind. I suggest that you read up on Dr. Rhodes Fairbridge's hypothesis about planetary gravity affecting the solar cycles.

No, just a retired engineer. If you don't understand what I said, just say so.

Re: "a weak geomagnetic field due to magnetic pole reversal and a star in the prime of it's life burning hotter than ever"
The pole reversal I was discussing in the ABC forum but I can't find any information on it. Do you know of any articles or papers on it that I could access?
The burning hotter thing I don't know about. I was told the heat that reaches us is a constant of 1.99 or something like that. Can you be more specific?

After rereading my original comment I see that I was not clear about the connection between the statements. Sorry about that.
There is a ridge under the Arctic that connects to the northern part of the mid-atlantic ridge. It normally spreads at about 10mm per year (very slow). Volcanos erupted quite violently along it in 1999 and 2001 and at about the same time there was a magnetic pole shift in the direction of siberia. I believe that these events are related.
The Multidecadal Atlantic Oscillation shifted gears last year and so did the PDO. The ENSO has been more severe since the late 1970's. I believe all of this is related to changes in currents in the magma.
Dr. Fairbridge explained that the gravitational forces of the planets, especially Jupiter, have an effect on the sun which increases with planetary alignments.
Logically, if a full alignment can affect the sun it also should have a similar effect on the earth.
The last full alignment occurred in 1976, exactly when the solar forcing stopped following the earth's surface temperature curve. I do not believe that this was pure coincidence.

Some how this will be Barack Obama's fault, LOL!
Posted by: Fired UP!! | Jul 4, 2008 9:45:16 AM
It's been an accurate observation for years from people living in the Gulf of Mexico regions that increased water temperature in the Atlantic increases the possibility for hurricane formation. Sorry, but it's hard for me to buy into the notion that moisture from the mountains in NE mountains are the origin of hurricanes in the Atlantic. It sounds like a denial of the obvious, global warming.

So, how will John McCain blame this one on Barack Obama too?
Posted by: Mikdy | Jul 4, 2008 12:06:13 PM
kathy - I think what was meant was that some portion of the seeds of the circulation patterns may get started (or altered?) in northeastern Africa; they are waves in the atmosphere's flow; some of these reach conditions over the ocean where they can fuel up with water vapor and turn into tropical cyclones.
Quietman - the known forcings (a large warming from anthropogenic CO2 and other greenhouse gas emissions accumulating in the atmosphere, a significant cooling from anthropogenic aerosols, some relatively small contribution from the sun and episodic volcanic eruptions) are sufficient and expected from the physics to result in the global warming observed. The knowledge of the mechanism of the greenhouse effect is established - I would only that there would be global warming if CO2 is added to the atmosphere. The burden of proof is satisfied for significant anthropogenic global warming; that their is some uncertainty remaining, particularly in cloud feedbacks and regional effects, does not set the burden of proof back on AGW as a significant and serious matter (not that you brought that up).

"I would only that there would be global warming if CO2 is added to the atmosphere."
Insert "expect" into the above after "only"
