THE SPARK GAP A monthly publication of the Meridian Amateur Radio Club July / August 2001
First things first! Field day was outstanding! I have never participated in a more enjoyable field day. Everyone pulled together to make this year's field day the best yet. Our field day committee, Mel & Margie - Deb & Darrell - Jim & Brenda - Bill & Debbie - Michael - & Russell went out of their way to see that all went smooth. The weather was great and the site at Bonita Lakes was the greatest. The food committee, Margie - Deb - Debbie - Brenda and all others who cooked or brought food, THANK YOU!!. (Ya did good!!)
Thanks to Jim, Mel & all of the VE's who taught classes and tested last month. Congratulations to all who passed their test and those of us who didn't, better luck next time. We have accomplished much this year as a club and have plans for a lot more. Join us at our meetings and help us plan.
We have been blessed with good weather lately but we need to keep our guard up just in case. Thanks again to all who pull together and make this club it's best...

We convince ourselves that life will be better after we get married, have a baby, then another. Then we're frustrated that the kids aren't old enough and we'll be more content when they are. After that, we're frustrated that we have teenagers to deal with. We'll certainly be happy when they're out of that stage. We tell ourselves that our life will be complete when our spouse gets his or her act together, when we get a nicer car, are able to go on a nice vacation, when we retire.
The truth is, there's no better time to be happy than right now. If not now, when?
Your life will always be filled with challenges. It's best to admit this to yourself and decide to be happy anyway.
One of my favorite quotes comes from Alfred D. Souza.
He said, "For a long time it had seemed to me that life was about to begin-real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, or a debt to be paid. Then life would begin.
At last it dawned on me that these obstacles were my life." This perspective has helped me to see that there is no way to happiness. Happiness is the way.
So, treasure every moment that you have and treasure it more because you shared it with someone special, special enough to spend your time with ... and remember that time waits for no one.
So, stop waiting until you finish school, until you go back to school, until you lose ten pounds, until you gain ten pounds, until you have kids, until your kids leave the house, until you start work until you retire, until you get married, until you get divorced, until Friday night, until Sunday morning, until you get a new car or home, until your car or home is paid off, until spring, until summer, until fall, until winter, until you're off welfare, until the first or fifteenth, until your song comes on, until you've had a drink, until you've sobered up, until you die, until you're born again to decide that there is no better time than right now to be happy. Happiness is a journey, not a destination."

Still they are, they exist and they call me with the flash and the cricket code.. Asleep in England no more or France or Moscow..
Far away and in my head..
Old friends of gold and those never met of tube and key, skipping over the ocean and bouncing from the sky.. Riding the tail of a comet, playing among aurora, then back to the deep blue water, the mighty mirror of the Sea..
From the flickering screen or the magic of a sky wave, in my earphones for no apparent reason with their "Donald Duck voices or with the happy whistling song of a telegraph key.. May they always be...
Weather analysis indicates were
beginning long-term upswing in severity
By Kathleen Wren
WASHINGTON, July 19 Since 1995, hurricanes have come rumbling over the Atlantic Ocean more often and with more intensity than during any other time in the last three decades. The catastrophic losses of life and property have prompted many to wonder whether this turn of events reflects a real trend, or just a weird run of bad luck. A study in Fridays issue of the journal Science concludes that the recent upturn is no coincidence: Atlantic hurricane activity seems to have entered a busy period that could continue anywhere from 10 to 40 years.
SUCH A SHIFT would have serious consequences. Lulled by the mild hurricane record of the 1970s and 1980s, people have moved to vulnerable coastal areas in droves.
Theres been so much buildup (along the coast). People have not experienced these storms recently and theyve forgotten what its like, said the studys lead author, Stanley Goldenberg of the National Oceanic and Atmospheric Administrations Hurricane Research Division.
HAVE HUMANS PLAYED A HAND?
According to the researchers, the hurricane system swings like a pendulum between more and less active modes of operation, each lasting several decades.
In contrast with previous 24 years, which have been relatively quiet, the last six years have seen a doubling in overall hurricane activity coming from the Atlantic Ocean, with a fivefold increase specifically in the Caribbean.
A commonly asked question is whether this increase might be due to global warming. The new results suggest that the answer is no at least not primarily. The hurricane track record of the last six years looks similar to the one from the 1920s to the 1960s, when major hurricanes were also relatively common. Goldenberg and his colleagues think the recent upsurge in hurricane activity is more likely the latest swing in the long-term cycle.
Saying that this increase in activity is from global warming is like saying that its getting hot right now because of global warming. Actually, the real reason its getting hot is that its summer, Goldenberg said.
The scientists arent exactly sure yet what actually drives the cycle that causes hurricane activity to wax and wane periodically. Some researchers have proposed that the global system of ocean circulation may be responsible, but more research is necessary to be certain.
Its also conceivable that global warming might intensify the current conditions, making the pendulum swing a little higher, so to speak. Goldenberg did notice that this last shift has been more extreme than any other on record. Then again, the difference might also be the result of improved record-keeping.
These last six years were the most active of all recorded. So, the question is, Gee is that also because its also a little warmer than ever before? If were going to be honest scientists, we just cant answer that now, Goldenberg said.
SETTING THE STAGE FOR A HURRICANE
A hurricanes center is organized like a chimney, with warm moist air entering at the bottom and then spiraling upward. Two key conditions enable a storm like this to develop.
First, sea surface temperatures must be relatively warm, in order to feed the hurricane with thermal energy. The second factor, called vertical wind shear, is the difference in wind speed and direction between the upper and lower atmosphere. If the vertical shear is too strong, the hurricane cant assemble itself vertically.
Goldenbergs research team analyzed historical records of both these conditions. When the scientists looked at how the sea surface temperatures had changed over time, their first result was a collection of haphazard wiggles, seemingly without any logical structure. They used a statistical model to untangle distinct modes, or patterns, in their data, like distinguishing the sounds of individual tones in a piece of music
Once the global effects of the El Niño cycle officially known as El Niño-Southern Oscillation, or ENSO, had been removed from the data the authors could see another regularly occurring cycle in the Atlantic. For several decades, the surface waters would be slightly warmer, meaning conditions would be ripe for hurricane formation; then theyd cool down, switching over to an anti-hurricane phase for several decades more.
When you go beyond ENSO in the Atlantic, this mode pops out. Its very strong. These things stick their nose at you, said Alberto Mestas-Nuñez of the University of Miami, another author of the study.
The timing of the sea surface temperature fluctuations matched similar fluctuations in vertical shear, as well as the actual hurricane record since the 1940s. Thus, Goldenbergs team may have found the keys behind the long-term waxing and waning of hurricane activity.
More research is still necessary to understand the complex behavior of hurricanes, however. In a commentary article that accompanied the study, Lennart Bengtsson of the Max Planck Institute for Meteorology cautioned against drawing conclusions about long-term trends from the relatively short hurricane record.
HOPE FOR THE BEST, BUT
In their study, the Science researchers called on government officials, emergency managers, and coastal residents to prepare for a period in which the hurricane threat is much greater than it was in the 1970s and 1980s.
A particular concern, according to Goldenberg, is that in many coastal areas the buildings have not only become more abundant, theyve gotten taller as well. Recent observations have shown that hurricane wind speeds can be much higher several stories up than they are at ground level, Goldenberg said. So, the upper stories of a 30-story building could sustain far more damage than the lower floors or a shorter building right next door.
The saying Hope for the best but prepare for the worst really describes the situation, Goldenberg said. We cant say that one particular area is going to be hit by a major hurricane, but these data tell us that there will continue to be more activity and that we certainly need to take the hurricane threat very seriously.
