I used to wonder where these people came from. But that was before the Days of the Interwebs. They were hiding in the ether, mumbling to themselves. This guy is an incredible genius!!

Does it count that my kitchen and bathroom sink drains also make the water spin when it goes down the drain? That should be taken into account, shouldn’t it?

The idea might have some merit if the tornados always correspond with the direction of the traffic flow, but alas they do not.
But it is a good reason to get rid of roundabouts.

The only problem with roundabouts, is that most people aren’t smart enough to figure out how to use them.
My average commute has dropped by over 20% thanks to the addition of roundabouts.

I think it all started when LP records were discontinued.
This left a massive vacuum in the centripetal momentum of the universe, all centered on the surface of the Earth.
Tornadoes were the obvious outlet for all of that rotational potential energy left with nowhere to go.

Years ago at the prompting of one from the northern hemisphere I did a survey of drains in our southern hemisphere lab complex. Of the 25 there 12 went one way and 13 the other. The conclusion was that the hand of the plumber over-ruled.

This kind of sloppy thinking starts with the allocation of coriolis effects to swirling in effluent water – was never right:

Does water always drain counterclockwise?

It is a commonly held misconception that toilet water always drains counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere because of the Coriolis force an acceleration imparted by the Earth’s rotation.

The coriolis effect is much too weak to influence the direction when water from a pressure piping system falls to the drain and disappears into it – be it a toilet, bathtub or sink.

I recall a tv program a while back showing tourists in an equatorial African country (possibly Kenya) being treated to a demonstration of the coriolis effect (for a small remuneration, of course). A tin bowl with a hole in the bottom was shown with water swirling in one direction as it drained, then no more than a dozen steps south into the other hemisphere, the water was shown to rotate in the opposite direction.

Of course, the angle of the jug pouring the water into the bowl had absolutely no influence on the outcome.

This article says, “The United States sees the most tornadoes in the world, with an average of more than 1,000 tornadoes each year. Canada is second, with around 100 per year, and all other countries combined experience another 100 to 200 tornadoes annually. Measuring by land area, the United Kingdom has a higher rate than any other country, but most of the twisters there are relatively weak.”

The Great Plains region of the US is uniquely arranged so as to make tornado production common, a situation which does not occur anywhere else in the world – at least not on that scale, certainly. Tornado’s become likely whenever a large rapidly moving cold air mass from the north collides with a very moist, warm air mass coming up from the south. In Europe, for example, movements of this kind are blocked by the Alps, in Asia, by the Himalaya, and Africa and South America generally don’t get swept by large coldfronts.

But in North America, powerful fronts from the arctic can sweep down the plains, moving down behind the Rocky Mountains, where they collide with large tropical air masses coming up from the Gulf of Mexico. The places where these two forces collide with each other are where tornado’s happen – it is also why they predominantly happen in fall and spring, and almost never happen in summer or winter months.

WWS “almost never happen in summer ” That is not correct for the far north of the great plains Fargo in particular an F5 occurred on June 20th here and what Wikipedia said it ” is what Fujita reportedly called this more intense than the 1965 Palm Sunday tornadoes he surveyed, some of which he rated F5 in the Chicago Damage Area Per Path Length” Fargo season peaks around July 4. I will admit most were in late June but I have seen lesser ones occur in July and August. Here is what Minnesota DNR says about tornados in Minnesota “Minnesota have occurred during the three months of May (15%), June (37%), and July (25%).” The list for May through September in Minnesota from 1950 to 2018 is May 298, June 662, July 488, August 237 September 117, the only months in that time period Minnesota has not had tornados were December, January and February.

New England gets more tornadic storms than a lot of people realize. In our case, trees generally block the view, something that causes a bit of angst within visitors from the plains.

Here some people point out we have a similar situation with the Atlantic south of us, a decent feed from the Gulf Stream and GoM, and mountains from the Birkshires and Green Mountains of VT to help bring Canadian air down.

Yesterday was the anniversary of the biggest of them all, the 1953 F-4 (some claim F-5) tornado in Worcester, Massachusetts.

It had a number of firsts, including it was the first storm seen injecting water vapor into the stratosphere. A hook echo seen on radar provided confirmation of the hook echo described a couple months before in Ohio as a potential tornado signature

Driving on the left comes from walking and riding on the left, with (if present) your lady on the left. This meant that your right arm was free to draw your sword and defend. Driving on the right removes this advantage. It is clearly much more dangerous.

The problem with proving this concept is that so few cars go all the way around. Most go only halfway, which is roughly equivalent to parking, which also takes a car ten feet or so from the right-hand lane. If more cars actually went all the way around (i.e., performed a 360), we could set up anemometers at strategic places around the roundabout to check on induced winds. As it is, I can’t imagine that an actual circulation would be set up by cars slowing down to enter the roundabout, hunching over a bit to the right, sliding back the same distance left to the straight-ahead lane, and proceeding in the original direction. Just a thought, for the sciency types.

John M. Ware: “The problem with proving this concept is that so few cars go all the way around. “

Well, if you’re going to get all scientificky about it, cars are entering and leaving at all points of the roundabout. Although none but the rare, totally confused driver goes all the way around, the sum of the cars entering and leaving is what creates the vortices that create the tornadoes.

Let’s get our science right, shall we?

Roundabouts are creating more problems than tornadoes by itself. Who in sane mind would voluntarily reduce capacity of 4 crossing roads from 5000 cars/hour to 1200 cars/hour.
And suddenly on main road you have T section…
Not last roundabouts are very ecological.
Average passenger car need around 0,05l – 5 deciliters of fuel to slow down in front of roundabout and speed up after.
20 tonnes truck needs 1 liter of fuel to slow down and accelerate. And it is doing that so slowly, that if passenger car is behind truck, it loses around 1km of distance.

Well, on my drive to/from work, there is a particular intersection. It’s only a three-way intersection, and it’s in a “rural” area, but it got a lot of traffic. With the traffic lights, it got regularly backed up. There were times it took me ten minutes to get through it in the evenings.

They put in a two-lane roundabout instead, with one through lane going from east to west. Now, the most I have to wait when going through there is maybe ten seconds, most of the time I don’t have to wait at all. So I’d say that roundabout has increased traffic flow tremendously in all directions. But you occasionally get the odd A-hole that doesn’t feel he needs to yield to traffic in the roundabout, or the idiot who stops when there is no traffic in the roundabout.

Every place I’ve seen a traffic circle installed, traffic capacity has gone up.

Peter
Reply to  MarkW
June 12, 2019 1:18 am

Maximum capacity of single double lane road is around 6000 cars/h. 1.2 second between cars in each lane.
Maximum capacity of 4 way stop is around 900 cars/h (one car each 4 seconds when it is fully clogged). Each incoming lane capped at 900 cars/h.
Maximum capacity of single lane roundabout is around 1200-1600 cars/h. Each lane capped at 1800 cars/h. But after yielding collapses to 900 cars/h from lane with creation of congestion. Over 1600 cars/h from any direction it collapses.
Maximum capacity of single line traffic light X intersection is around 1800 cars/h. 4 seconds/car from 2 directions in average.
Maximum capacity of traffic light X intersection where single lane changes to double lane in intersection is around 3600 cars/h.
Maximum capacity of X intersection without lights main/side road is up to 6000 cars/h. Only disadvantage for side road.

From capacity point of view double lane traffic light intersection is better option than roundabout. It needs basically same area as roundabout but it is 3 times more effective than roundabout.
Roundabouts works only in narrow window of capacity 500 – 1600 cars/h. Less than 1000 cars/h main/side road intersection performs better. More than 1600 main/side still works, or double lane light intersection is better.
Double lane roundabouts are better than single lane but not two times better. They can be somewhere around 2700 cars/h, they are huge and not pleasant to drive, confusing too.

with traffic light you still have 50% chance not to stop. With roundabout not. You are still slowing even without traffic. I’m usually slowing from 100km/h to 20km/h. Losing 96% of my kinetic energy 1/2mv2. Kinetic energy equals to second power of speed, this is why it is harder to slow from 140km /h to 100 than from 40 to 0.

No. Vertical axis. Rotation is counterclockwise in Northern hemisphere.

I thought tornadoes started as a mass of air spinning on a horizontal axis.

There is a little more to it than that.

Just, stay away from the “Solving Tornadoes” fiction written by James McGinn.

John Isaacs, a renown oceanographer at UC San Diego, thought something similar–that cars passing one another on the right were putting cyclonic vorticity into the atmosphere. Published a note on the topic back in the 1960s. Even smart people have a few loopy ideas.

Yes, I recall a similar publication where they showed that more tornadoes occur near interstate highways. Of course, there are more people to see tornadoes on interstate highways, so it’s probably an observational bias. Even if cars passing each other generate positive vorticity between them, they generate negative vorticity on the outside, and the net effect over, say, a couple hundred yards is zero, I believe.

Yes, averaged over a hundred yards it has to be near zero. Thus Feynman’s dictum that if you don’t take an argument to completion you can prove all sorts of things that aren’t so.

jmorpuss will chime in here shortly with a recommendation to see the “Solving Tornadoes” self-published book by the nitwit (James McGinn) who fails to understand how the ‘water cycle’ enters into the picture in combination with clashing air masses …

N.B. water cycle – the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

If Americans drove on the proper and natural (Left) side of the road the effect would obviously be to counteract any incipient Tornadoes and render them inert!

Yes, but if you look at the Benz vehicle you can see the driver’s position is on the vehicle centreline.

Ergo Benz was either a fence sitter or deeply concerned about massive tornadoes ripping through the Black Forrest, and hence refused to set a left/right precedence for safety reasons.

Also, I am lead to believe that the worlds first legal definition on the left/right issue was made in London in regards to traffic crossing London Bridge. It is from this historical declaration that the folk song ‘London Bridge is Falling Down’ clearly springs, for if one reads deep into the lyrics there are clear indications of the grave risks of right side of the bridge created vortexes producing catastrophic failure. The British were clearly not going to stand for a constant cycle of vortex and repair and as a result made a grand effort to ensure their children understood the bally dangers from a ripe young age.

By extension it can then be clearly shown that this early cultural training has lead to a state of affairs in modern Britain where tornadoes simply are not a problem, although the fact it now rains constantly is usually swept under the carpet.

And that, Ladies and Gentlemen, is how SCIENCE! is done.

Probably… 🙂

In the “Failed to Explain” category (by the ’roundabout theory’, or the “Solving Tornadoes” theory as well) – we have dust devils, and where I saw the most dust devils were out in the western US, under clear, sunny skies over the desert landscape.

Can’t be. Tornadoes rotate clockwise, traffic circles (roundabouts) go counter-clockwise (in the USA).

There are a couple of roundabouts in the UK consisting of 7 small roundabouts linked together…

I think these are causing interdimensional vortexes…

First, I need to restore the correct terminology of “traffic circles”, which everyone wants to call “roundabouts”. Second, traffic circles are closely related to crop circles, except they can’t form over unpaved fields, but generally require asphalt. I have personally seen strange vehicles on the traffic circles, which must be the ones creating them. 😉

Reminds me, in a back to front way, of the alien reporting back to his superiors after a visit to earth;
“Yes, sir, they enjoy the smell of their oceans so much that they have vast arrays of propellers blowing the sea air around their world.”

What other logical reason would a member of an advanced civilisation possibly think of for these constructions.

In the USA, I think the term has always been “traffic circle.” But my TomTom (European company) calls it a “roundabout,” and I’m not sure but I think Garmin (U.S./Swiss company) does the same, which probably means the Brits are going to win this argument.

Oops! Correcting myself: TomTom calls it a “rotary.”
Thank you, Juan, for reminding me.

We invented roundabouts and we named them. There’s a regrettable tendency amongst Americans to rename things according to what they are used for, rather than what they are.

Well, it’s not the stupidest thing I ever heard, but it’s close. First prize goes to a young lad (21) and his girl friend (19) that I hired to help me move some furniture out of a storage locker near Edwards AFB to a new apartment in Arizona. Passing through the wind farm at Banning pass he asked what all those big propellers on towers were for. Unable to suppress my natural tendency to be a smart-a$$, I replied that it was an experiment and when the smog in LA got too bad they would turn them on and suck the smog out into the high desert where it wouldn’t bother anybody. Their only question was, “Does it get all of it out, or only a little?” They actually BELIEVED it! And I learned a valuable lesson about the dangers of being a smart-a$$.

I have a corollary social theory here. The reason that the UK is so much more socialist than the US is that your traffic engineers make it very easy to make a Left turn, and devilishly difficult to make a turn to the Right.

Here in the Rebel Territories, it is the opposite. Very difficult to make a left turn. Case in point is my city.

For a while, we had “suicide left turn lanes” – they reversed the direction and banned left turns depending on whether it was morning or evening rush hour. Then we have the mix of preceding and following signals, that seem to have very little reasoning as to where they put them. NOW they are busy remodeling intersections to make it so you have to go through the light, then make a U-turn, get across three lanes of oncoming traffic, and then make a Right turn if you want to go Left.

Not all that many traffic circles, though; a few on residential streets (mostly around the University, where they really don’t know which way they’re supposed to go on any one day, especially when they don’t get copied with the appropriate ideological memo).

In NZ, if turning left, you have to give way to traffic turning right in the opposite lane. Then there are 3 turning rules at an intersection depending on the road markings.

Interesting article. Unfortunately the author has conflated by use of the word denier the “flat earthers” with climate sceptics. The implication being that both should be treated with equal ridicule and that his own opinions on climate change are elevated because our world is so obviously a spheroid.

The coriolis effect is much too weak to influence the direction when water from a pressure piping system falls to the drain and disappears into it – be it a toilet, bathtub or sink:
