Brake Story and Other Car Adventures

When i went to Jiffy Lube (Wednesday, Lake Oswego) they also checked the brakes. 8 mm left in rear (which i done myself this spring) and 0.3 mm in front which i was expecting. So i planned to go today and do those ((bought the OEM plates in the same time with the rear ones) also a very nice and worm fall day). I went to the car to check the e-brake and ready to start when i saw the yard was full of smoke. Mole mounds, holes and galleries everywhere. Kids on bikes playing next to my cars ignoring the traffic in the 300 apartment complex (we're at the bottom of the cul de sac but still). Something i wanted to tell for sometimes and keep forgetting. I go outside, the light makes my eyes itch (yes, didn't wash my face this morning). I was coming from the yard after stepping on a number of mole features, smoke was reduced a lot, my eyes started to itch, i started to rub them with my fingers and Victoria Lugosi popped from around the corner. And i hear one low flying plane approaching.

  • It took me a while to take apart left front wheel. Bolts where over torqued (by me?). The three kids passed back and forth a dozen of times.
    There are some adults watching them at the end of the alley. But now they came and stare right at me.

How Weather Works

It's been a while since i wrote a blog post with the same title. But that post was not comprehensive and certainly not exhaustive on the subject. In the public's confusion surrounding this area of knowledge i missed something very important or about half of the picture. Don't know if i could do it right now but i'll try since there is nothing better to cling to when trying to explain things (or build a good conspiracy theory). As in many sciences, during the IT era or 3rd industrial revolution there is much confusion in meteorology as well and the reason could be some at the top of the world are gaining from it. Simply put, there is not enough convergence of interests or focus from the general public to push for the humble truth in this area.

As then, i'll start with a picture - just finished getting accustomed with the new blogger interface so now i could do it but not easier and certainly more complicated than with the old one.

What keeps the planet spinning? The force from the beginning. Quoting from a very popular song though moving out of playlsts at the time of this post. (Got to go in html mode to insert the picture, otherwise it get inserted at the beginning of the post as per (new) blogger interface, see you guys later).

Back in compose mode. Earth. Round, not flat model. It's a sphere but it spins like a whirligig. (The gyroscope effect keeps it on the same 23 degrees angle with the plane of trajectory around Sun).

Obviously, its surface speed is different at equator where it's bigger than at any other latitude including at poles where it's is zero.

Now imagine you're in a plane that flies from equator to pole. After taking off, you will have to navigate in such a way to loose that part (component) of the speed. Your trajectory will be not a straight line but i think part of a parable. The deceleration of that component (parallel with equator) of your speed will not be felt though. From 1000 mph to 0 in 10 hours or so? Nuh - hu. Nothing.

The space travelers where always interested in that speed. For this reason they build their launchers as close to the equator as possible. To freely get that 1000 mph and add it to their launch speed, to escape earth gravity cheaper before maneuvering for reaching final orbit.

Got your head spinning already? No? Than imagine you're one of those guys in the picture on a much smaller Earth or you're a much taller guy, like 10 miles tall and try to walk from equator to pole in about 10 minutes. You'd have to walk at an angle because you'd have to loose (beat) that momentum of the equatorial speed. In mechanics, it's called  the Coriolis effect.

Now imagine you're a wind, like Ann Wilson's' lover in that song and try to blow from equator to north.

Cause this is what happens actually. Air is getting warmed up near equator, looses density, gets lighter and goes up and then in the upper side of the atmosphere, not having where to go it splits north and south as it's being pushed by more air going up that attracts fresh air from north and south on the lower side, like in a vertical convection cell (or two, one one both sides of equator).

But what happens to the equatorial speed component of that wind going north? At higher latitudes it turns into jet streams. Fast flowing high altitude air currents that go from west to east, meandering in the sky. Airline pilots have already learned how to ride those, and save fuel and time, if available in their path.

And that somewhere is right back on top of equator. And when things really heat up, like during summer in northern hemisphere, those cells are being broken and between those two air currents, the jet stream and equatorial flow, you have guessed. A tropical cyclone will take place of the cell. And when that cyclone meets a jet stream meander, it will follow it up north. Back to html.
Back to compose. This image is simplified. To show the cells, they neglected the meandering of the jet streams which are shown as pink straight lines. In reality jet streams are meandering and cells are irregular and sometimes interrupted, this is just to show the general image. I think everybody who read this so far have got it.
 
Tropical storms are formed between jet streams and opposite equatorial flow (i guess i'll call it like  this for now). Equatorial flow is more stable while jet streams are meandering and determine weather swings in temperate regions (warm south of jet stream, cold north and rain right in it when there's enough moisture) and even the path up north of tropical storms. But i think they both contribute to the formation of tropical cyclones since those are always caught in between jet streams and equatorial flow and their direction of rotation is determined by the opposite flow of those two.
In this image that shows jet streams meandering, westward (opposite to jet stream) equatorial flow is not shown.
In the image above it is shown the current (post time) jet stream situation over US. South of the most southern meander there is a cyclone, shown on this map with isobars (lines showing same atmospheric pressure) circling each other. Due to centripetal force, pressure is lowest in the middle of the cyclone.

Not shown, south of that cyclone there is the westward equatorial flow that together with the jet-stream create that cyclone.

Now why is it raining only in areas where there is enough moisture and high speed winds upper in the atmosphere (inside jet streams and cyclones). Simply because of Bernoulli's law, that is where there is high air speed, there is low air pressure and condensation occurs and droplets and then bigger drops form in the atmosphere wherever there's low pressure.

But where is that promised juicy conspiracy theory? Jet streams flow at the point of balance of massive amounts of air being exchanged between equator and tropics, "venting"  the rotation momentum of those masses of air when going north. Their meanders are changing quasi randomly and are highly unstable.

My idea is where there's randomness and balance and instability, there is always the possibility to tip that balance using relatively low amounts of energy and that could be done with devices that have their declared purpose of punctually heating the ionosphere (HAARP) or simply with very tall and mechanically strong antennas that can electrostatically raise or lower the ionosphere. On the surface, winds can be created or reversed with thousands miles long electrostatic fans, similar to those used in some home air purifiers.

About the verses from that song. Yes, energy from Earth's rotation momentum is being lost in friction of air moving due to Coriolis effect (like it's lost in friction created by flow because of tides due to Sun and Moon gravity).

Don't know how much and if it's enough to change temperatures and if it's gonna stop the Earth after a billion years or so but still.

Fire and Rain

This is the fire situation in western states as of today (post time). You can see fires grew back since after last rain that i managed to catch in a different blog post. (That post is done through a different method, screenshots in a slideshow, that is very time consuming. Much easier with gifs, but there is no easy way to pause them when playing in html).

Since, the jet stream moved way up north leaving an area of high pressure, high temperature, low winds and especially no rain. Time shown on the map is PDT+7.

The reason i came up with this again is frustration with the smoke. But when i looked today again on the visible and infrared satellite images i saw the situation is much worse in central California. And it looks like it's going to stay that way unless it doesn't rain. Maybe for months. And  then my frustration grew bigger. And i remember something i wrote several times in different posts and wanted to put them together once and for all.

Here is a very comprehensive explanation of what jet stream are. Rivers of high speed air way above surface winds, flowing always west to east (except for meandering).
They are mainly caused by the difference in speed of surface of Earth between equator and pole. They are important because in temperate regions they are determining the weather. Above or at higher latitudes is cold, below is hot and right under is where the precipitations generally occur (except for cyclones but those are also formed within the meanders of the jet stream).


Here is by example the current jet stream situation over Europe

And the powerful cyclone it formed.

However, i think there is a possibility to alter the direction of jet stream. Imagine you have a huge microwave antenna (similar to radar but much more powerful) pointed to the sky that can punctually heat up the ionosphere. If you heat it up let's say, left of the jet stream, it's gonna steer left, etc.. Now you also have some supercomputers with real time global weather models that can calculate where exactly you should hit it to get most of the effects all the way to thousands of miles downstream.

This of course can not be done with huge electrostatic high voltage DC fans like the Pacific Intertie. You will need something else, which needs to be located also at the most western point or entry area for jet stream in the US. Alaska.

This is the current situation of jet stream over northern US. After staying for about a week, beginning two weeks ago, on top of Oregon and California, last week it moved the way it is right now and it looks it's going to stay like this for a while which is kinda unusual because it should change direction more often. This configuration promotes unchanged weather and winds over Oregon and California at least until the end of next week when there's 50% chance of rain in forecast in northern Oregon. Unlike normal atmosphere, ionosphere is conductive. And you know what happens if you put by mistake a piece of aluminum foil in the MW. It heats up and melts.

"The High-frequency Active Auroral Research Program (HAARP) was initiated as an ionospheric research program"

"This is a high-power, high-frequency phased array radio transmitter with a set of 180 antennas, disposed in an array of 12x15 units that occupy a rectangle of about 30–40 acres [12-16 ha]."

How much power and what frequency? It can peak in GW and MHz range.

Many people don't understand what a phased array antenna is. They are used mostly for modern radars and have no moving parts.
Instead, the beam is steered electronically, by shifting phase at each element (in this 2D theoretical desmos example you can simulate shifting phase and steering the beam by moving the second slider and front propagation by moving the first). For a radar it means you can steer the beam hundreds of times a second to cover a wide cone (smaller than 180 degrees) in front of the antenna, like the electron ray in an old CRT TV. For HAARP antenna it means the beam can be steered in almost all directions above horizon, covering a radius of hundreds of miles at the ionosphere level. So you can heat precisely one point of the ionosphere in the area where jet-stream enters most of the times the American continent.
"HAARP is a target of conspiracy theorists, who claim that it is capable of "weaponizing" weather. Commentators and scientists say that advocates of this theory are uninformed, as claims made fall well outside the abilities of the facility, if not the scope of natural science."

If you think in terms of heating the air, of course, it is outside its abilities and scope. However, you don't need to heat the air to change the weather, you only need to steer the jet stream by punctually heating the ionosphere which falls well within those two categories.

"In May 2014, it was announced that the HAARP program would be permanently shut down later in the year. After discussions between the parties, ownership of the facility and its equipment was transferred to the University of Alaska Fairbanks in August 2015."

I first wrote about the possibility of weather manipulation by steering the jet stream in November 2012.

https://georgesblogforfriends.blogspot.com/2012/11/how-weather-works.html

I think besides these two described above (HAARP, Pacific Intertie) there are other ways in which you can mess with the weather, like using huge antennas (Eiffel tower, other unusually high towers with multiple purposes) to electrostatically raise or lower the ionosphere, influencing the pressure in the atmosphere and ultimately the jet stream, or my favorite, simple and elegant catching clouds antennas in areas with low and slow clouds like the one in front of GSR resort in Reno.

Here is this image you can see the "legs" of Eiffel tower sit on a foundation made of limestone.

"This cement was used for the base of the foundation piers. After, large limestone blocks were placed on top of the cement and covered by layers of cut stone."
