# Mage School 102

I've just been to a writer's group and told to make my stuff more accessible by coddling it in chocalte and silver paper. …

That's not going to happen.

Effing Microsoft crap from the public library computers. I'd have had all this online by now….
And I still have'nt opened Notepad!

So because I have only 26 minutes left, Here is the first instalment warts and all:

Windscales

The problem with charts is their formatting changes with the internet and from computer to computer. I am going to experiment with PDF and Opera as most of my stuff requires the use of charts. With a PDF file you at least get the same image whatever the computer being used.

Unfortunately you lose a lot of functionality even with Linux which can cotain tools to copy and paste some unprotected PDF files.

I do not like to use anything that isn't universally free. My stuff was given to me freely and quite a lot of it came from sources so majestic it makes me think that admitting it will put people off. But when you have been given a gift you have to live with the consequences.

THere was a prophet once in ancient Israel who was given a very unpopular commission. But he was given it from god so he must have thought: WOW!

Just like I do -or did.

Then the unpopularity of the effort and the immensity of it slowy got him and he refused to continue.

But it was in his bones by then and he couldn't stop.

You have been warned!

These are charts of sliding scales. In NO WAY do they indicate the terrible powers involved.

Consider the power in a soliton.
A soliton is a wave. Any single wave.
It might be created in a bath or a swiming pool.

It's easy to make waves in a bath but you can't see for long any you might create in a swimming pool.
They fade to nothing so quickly.
This fading away is the inverse square law that so attracted Newton when he had a few years off.

Power dissipates in a mathematical ratio between amount and distance. Light disperses in proportion to the area it spreads out to; as you will have seen if you put a flashlamp or torch up against a wall on a dark night.

And energy once released will dissipate as fast as it can.

So a wave holding its course and height must contain some sort of devilish device to enable it to hang in there.

Say it is 2 feet high and stretches halfway along the beach a mile or so. It is roughly semicircular.
So you can work out how much water there is in it.

And there's more.

Since I am no good at maths I will leave that to you.
If you are a clever bugger you can write and tell me the dimensions of an huge Hawaiian surfer's tunnel.

Note:The Beaufort scale had been known for thousands of years. It is based on the winds and sea states that cause ships to alter sail and change course. Designated by the needs of a frigate in the Royal Navy, the Beaufort scale turned out to be logarithmic, its intensities are on a “sliding scale”.This sliding scale is met with throughout earth science. The impacts of earthquakes on buildings for instance is given as a sliding scale.Pun not intended.Whilst I am fascinated by earthquakes and find them an exciting challenge, I am perfectly well aware they can be tragic. The same is true for storms and all other geo-phenomena.Until recently I attempted to align the impact of an hurricane with the subsequent earthquakes. It was comparatively recently (following the MegaQuake in Japan in 2011) that I realised it was a combination of weather systems and their relative centres around the earth that set the parameters for an epicentre and its magnitude.Have I lost you?To some I am going to seem patronising and to others just boring but to some it is a way into an interesting hobby so:By sayin I was aligning the two phenomena; I wished to compare them. I wanted them to fit together.I thought that when a storm hit the shore, it splattered like a bullet hitting a stone. And the force was equal in every way to a place in the earth where it back out as an earthquake.It seemed reasonable to suppose that an F1 hurricane could provide an >M6 earthquake.I still don't have much trouble with that idea -except of course for their timing.Their "first cause" is the same.Therefore they have to happen at the same time.And of course the power involved means all the hurricane has to arrive at the epicentre and the earthquake must wait and build up.But power dissipates immediately if it can. So what is causing the hold up?Sometimes it can be many days after the hurricane dissipates before the earthquake strikes. How do I explain that?Sometime it takes weeks, an impossible connection.

Saffir-Simpson Hurricane ScaleCategory Wind Speed; Pressure1 65 to 83 knots; 74 to 95 mph; 119 to 153 kph ; > 980 mb Storm surge generally 4-5 ft above normal. No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Some damage to poorly constructed signs. Also, some coastal road flooding and minor pier damage. Hurricanes Allison of 1995 and Danny of 1997 were Category One hurricanes at peak intensity.2 84 to 95 knots; 96 to 110 mph; 154 to 177 kph ; 980 – 965 mbStorm surge generally 6-8 feet above normal. Some roofing material, door, and window damage of buildings. Considerable damage to shrubbery and trees with some trees blown down. Considerable damage to mobile homes, poorly constructed signs, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of the hurricane centre. Small craft in unprotected anchorages break moorings. Hurricane Bertha of 1996 was a Category Two hurricane when it hit the North Carolina coast, while Hurricane Marilyn of 1995 was a Category Two Hurricane when it passed through the Virgin Islands.3 96 to 113 knots; 111 to 130 mph; 178 to 209 kph; 964 – 945 mbStorm surge generally 9-12 ft above normal. Some structural damage to small residences and utility buildings with a minor amount of curtain-wall failures. Damage to shrubbery and trees with foliage blown off trees and large tress blown down. Mobile homes and poorly constructed signs are destroyed. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane centre. Flooding near the coast destroys smaller structures with larger structures damaged by battering of floating debris. Terrain continuously lower than 5 ft above mean sea level may be flooded inland 8 miles (13 km) or more. Evacuation of low-lying residences with several blocks of the shoreline may be required. Hurricanes Roxanne of 1995 and Fran of 1996 were Category Three hurricanes at landfall on the Yucatan Peninsula of Mexico and in North Carolina, respectively.4 114 to 134 knots 131 to 155 mph 210 to 249 kph 944- 920 mbStorm surge generally 13-18 ft above normal. More extensive curtain-wall failures with some complete roof structure failures on small residences. Shrubs, trees, and all signs are blown down. Complete destruction of mobile homes. Extensive damage to doors and windows. Low-lying escape routes may be cut by rising water 3-5 hours before arrival of the hurricane centre. Major damage to lower floors of structures near the shore. Terrain lower than 10 ft above sea level may be flooded requiring massive evacuation of residential reas as far inland as 6 miles (10 km). Hurricane Luis of 1995 was a Category Four hurricane while moving over the Leeward Islands. Hurricanes Felix and Opal of 1995 also reached Category Four status at peak intensity.5 135+ knots 155+ mph 249+ kph < 920 mbStorm surge generally greater than 18 ft above normal. Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. All shrubs, trees, and signs blown down. Complete destruction of mobile homes. Severe and extensive window and door damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane centre. Major damage to lower floors of all structures located less than 15 ft above sea level and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5-10 miles (8-16 km) of the shoreline may be required. There were no Category Five hurricanes in 1995, 1996, or 1997. Hurricane Gilbert of 1988 was a Category Five hurricane at peak intensity and is the strongest Atlantic tropical cyclone of record.
