LOCAL VIEW –Hurricane Heights Demonstrated–

Schooner 1 03_1

Last week I talked about the old captains of coastal schooners, and the way they studied the sky for signs of “Hurricane Heights”.

Before railways were built in the mid 1800’s the main way to ship things was by boat, (which is why we speak of “shipping” things, even when we use trucks.) New York City was so big and growing so fast it had an insatiable appetite for lumber, and not all could be supplied by barging it down the Hudson River. Good money could be made “schooning” lumber down from Maine, but, before the Cape Cod Canal was built in 1914 (and widened to its current size 1935-1940)  the route south was nearly 150 miles longer, and involved going outside Cape Cod, which was that much closer to the hurricanes people on shore hardly noticed because they had “gone out to sea.” Even when the hurricanes’s winds were to the east huge waves traveled outwards, and when they reached the shoals off the elbow of Cape Cod they could turn waters a ship could ordinarily navigate over into a landscape of breaking waves, huge combers far from a beach,  with troughs so deep a keel could hit sand. Therefore a wise captain kept “an eye to the sky”.

This was done in a manner we can’t imagine. If we tried to force ourselves to study the sky we would soon start to fidget. Our minds would wander, and before long we’d get up and go to see what was happening elsewhere. However the old captains were stuck at the tiller or helm, and couldn’t go anywhere any faster than the boat was going. They studied the sky for hours upon hours.

One thing was very important to know, and that was whether the wind was going to back or veer. This was especially important when heading upwind. Without engines a ship had to tack to and fro, and (for example) a north-bound ship’s course could be made shorter if you knew beforehand whether the the headwind was going to shift to the northeast (veer) or to the northwest (back).

A rough idea where the nearest storm was located was to face the wind and stick out your right arm and point. You were pointing at the storm. But what direction was it moving? To guess at that you would look up at the high clouds, which moved with upper air winds that “steered” the storms. Then, by having a rough idea of whether the storm was approaching or departing or moving parallel to the ship, the captain would have a rough idea whether the winds would pick up or die down, and how they might back or veer.  On dull days this merely shortened the route and number of tacks necessary, and on more exciting voyages it might be the difference between successfully reaching safe haven, or shipwreck and death.

Few would bother study the sky to this degree now. What would be the point? Now, if a captain wants to go upwind, he just takes down the sails and turns on the engine. There are a lot fewer shipwrecks now, but modern captains are dimwits compared to the captains of yore, when it comes to eyeing the sky with understanding. The need is no longer there to sharpen wits to that degree, and in fact if anyone now spent that much time studying the sky we might call them “obsessive”.

Personally I feel a certain amount of obsession is necessary, if you want to ever be really good at something. One person who seems really good, concerning the understanding and prediction of hurricanes, is Joe Bastardi, and he quite freely confesses he obsessed on weather maps so much when young that he was in some ways a nerd. But it paid off in terms of genius. Some years ago he looked at a tropical depression off the coast of Africa and said, “Houston, we have a problem”, which some say is one of the best long-range forecasts ever made.

Last Monday he said it looked like we could have frontal remnants becoming a storm like Brenda in 1960. I said, “La-la-la! I’m not listening”. Why? Because I want to pretend I’m an old schooner captain, and trying to see signs of storm only using my eyes and a barometer. (Of course I did hear Bastardi, but I can pretend I didn’t.)

Friday the skies were as blue as they get, and the air refreshing and cool, which is a reprieve but also a reason to be on guard.

The passage of a Canadian high-pressure is often a prelude to trouble brewing to the south. (Bastardi calls high-pressure to the north “A ridge over troubled waters.”[Hat tip, Simon and Garfunkle.]) Not that you want to spoil your summer by worrying every time it’s sunny, but you watch for the return of clouds and the southerly flow behind the high pressure. And sure enough, when I awoke Saturday morning the newspaper had arrived, not on my doorstep, but in the sky straight overhead.

What would such a newspaper tell an old schooner captain? I see two clues he’d see in the scene below, plus a clue he wouldn’t see.

High clouds 2 IMG_7003

First, just over the pines to the lower left is a bit of low cumulus, so low you could almost call it scud.

Right off the bat, his farsighted eyes squint to determine what direction those low clouds are moving. If they are moving to the right and approaching then the wind is southwest. That would be a benign wind, as the storm would be to the northwest, and likely a summertime Alberta Clipper. At worst, if it was hot and muggy, a Clipper might swing down a cold front and bring thunder,  but the air is still refreshing and the sky is still deep blue and Canadian, so thunder is unlikely. But, because the captain has time to watch the sky, he notes the low clouds are not approaching; they are moving to the right and retreating. The wind is not from the southwest, but from the southeast.

A southeast wind is a whole different kettle of fish. It means a storm is to the southwest. Something may be coming up the coast. A certain wariness awakes. (I should note more than eyes were used by schooner captains. Like a dog (whose morning newspaper may be a fire hydrant) he sniffs the air, as a southwest land breeze has a completely different smell from a southeast sea breeze. He also likely runs his fingers through his hair, for hair tells you a lot about humidity. All his senses are involved; the sea is a sensual experience.)

Lastly he is very aware if the wind is backing or veering, and this southeast wind has veered all the way from the northwest through the northeast . For reasons I don’t understand, this is different from a wind that backs 180 degrees the other way, although it winds up blowing from the same direction.

Then his eyes lift a bit higher to the left, over the cherry tree, to the cirrus (which he would call a “mare’s tail”).

Cirrus is high clouds snowing into slower wind beneath. To the captain this is more reassuring than cirrocumulus, which is indicative of warmer air aloft and more inclined to be associated with hurricanes. Also the cirrus is still approaching from north of due west, which should “steer” a storm out to sea. However a rumple of concern appears on his brow, for he notices the high cloud’s movement is not as much from the north as it was. Indeed the high clouds are backing, even as the low clouds veer. Knowing nothing of upper air maps,  heedless of upper air ridges or trofs, the wheels in his head start whirring. If the high clouds back, and especially if they back with speed, look out.

However I have one clue he doesn’t.  There were no jets back then, and I can squint at contrails, and spot one over the trees in the center.

When contrails quickly evaporate behind a jet, it is a sign of descending and drying air aloft, and a sign of fair weather. When, as is the case with the contrail above, the contrail expands into a cloud, as if part of a cloud-seeding experiment, it is a sign of moisture aloft and rising air, and a sign of increasing clouds and approaching storms. (It doesn’t say what kind of storm: Gentle rain or hurricane or the squalls of a thundering front.)

Even without contrails the old schooner captains were likely observing whether high clouds were growing or evaporating. Where modern yachtsmen can set a “self-sailor” and be buried in a book, the skippers of yore would only “lash the helm” when there was a lot of other work to do. They liked the feel of the helm, and likely, by making subtle responses to each passing swell, could shave an hour or two off the length of a cruise.

When I was young I attempted to have spiritual experiences by closing my eyes, sitting cross-legged, and gazing up at the inside of my forehead.  I never lasted very long. Rather than sacred subjects my my mind gravitated towards how divine pizza or a woman’s body was. But at the helm of a sailboat without a self-sailor I was forced to pay attention or the boat might luff or jibe, and paying-attention became a sort of yoga leading to an altered state of consciousness. This divine intoxication is the reason some people are fanatics about sailing, while those who haven’t imbibed the wine cannot see the good of it, or why anyone in their right mind would willingly suffer seasickness.

How many modern people, with their short attention spans and craving for constant stimulation, can sit and watch a cloud as it passes from one side of the sky to the other? The so-called boredom would drive many nuts, and perhaps there is an element of craziness in being at sea. However it has its own constant stimulation, in the rocking of the waves and passing of the swells, the ruffling of sails and the ringing of rigging, the hypnotic slosh and thud and gurgling of waters, and it all combines to enter one into a different dimension, a different relationship with reality, with sea and sky. Call it “obsessive” if you will, but it includes the wisdom of the weather-wise.

Just looking at the clouds I’ve pictured above, the old schooner captains would have known “something was brewing” to the south. Would they have set sail?  Well, that was up to them to decide, and they did know how to handle a moderate storm. All business involves an element called “risk”.

And how do they compare with modern computers? Well, the billion dollar GFS Model never caught onto the coastal development until Saturday morning, right about the time an old captain would have tasted the first hints of a wind-shift to the southeast.

Others models did better, but how is one to chose? Even a single model can have fifty “runs” that all differ. Which one is right?

The answer seems to be obsessive, like Joe Bastardi. In order to be good at anything you need to in some ways over-do it. But Mr. Bastardi does amaze me. Last Monday he said that by Saturday a storm “like Brenda in 1960” could appear on the coast.  He also forecast that the weather bureau likely wouldn’t call it a hurricane, despite tropical characteristics. Then, on Saturday , there it was, looking all the world like a dying hurricane, though it had never officially been a hurricane and therefore could not officially be a dying one.

The weather bureau can bicker all it wants about whether things are “official”. I think they may be jealous if Joe’s ability, even to the mean level of not calling an event “tropical” because to do so might make Joe look better than they. But we are not suppose to become irrational, and envy is irrational. The simple fact of the matter is that Mr. Bastardi kicked their butts. And, when faced with superiority, the smart thing to do is sit at the feet of the master, and inquire, “How the heck did you do it?”

Let’s face it: If you had plans on the water off the coast of New Jersey or Long Island on Saturday, wouldn’t you like a heads-up that storm-force gusts like the feeder-bands of a hurricane could be coming north?

 

 

A final clue that this storm was “tropical” was shown by how quickly it is weakened once it cut inland.

What are we to conclude from all this? Perhaps we should conclude this: The next time we are called “obsessive”, we should respond, “Thank you very much.”

  1. It is amazing that the same people at the National Hurricane Center that rush to name phantom storms in the middle of nowhere, will inexplicably not name storms of tropical origin that are significant and dangerous for millions of people. Their incompetence knows no bounds!

    • What is amazing is that such people are unaware they look like complete jerks to all those who witness their vanity. You would think that vanity would make a person not want to look like a jerk.
