Fujiwhara?? When two hurricanes interact, they can sometimes pivot around one another. Next week there will likely be 2 tropical cyclones (perhaps 2 hurricanes) offshore. If they are strong enough, and are close enough, a #Fujiwhara may happen. Here’s how it works. Between the 2 storms is a pivot...

An incredibly rare situation as Imelda and Humberto *merge* in the Northwest Atlantic – two active hurricanes combining into one larger, more powerful hurricane! On Tuesday morning, Humberto and Imelda were separated by just 476.4 miles – second place to the record for closest Atlantic hurricanes. (Two hurricanes in 1853 made it to within 428 miles of one another). When hurricanes pass within 800 or 900 miles of each other, they interact in a rare dance called the "Fujiwhara." Basically, they dance around each other. Humberto was initially a much stronger hurricane. Over the weekend, it yanked Imelda eastward. That technically means that a hurricane helped spare the U.S. a strike from another hurricane! How ironic and bizarre is that!? But now Imelda is the stronger hurricane. It has winds of 90 mph, and Humberto's winds are at 80 mph. In the next couple days, Imelda will ingest Humberto's vorticity, or spin, and the two low pressure systems will fold into one larger, more powerful low over the northwest Atlantic. It will probably retain hurricane-strength winds, and it's likely the Hurricane Center will allow Imelda to keep its name! The Fujiwhara effect has happened before – iconic examples of the Fujiwhara dance were observed with Odette and Seroja in the Indian Ocean in 2021, or Hilary and Irwin in the eastern Pacific in 2017. The Fujiwhara effect happens with atmospheric vortices of all scales. For nontropical (midlatitude) cyclones to be influenced by each other’s presence and interact, they need to be within about 1,500 to 2,000 miles. Their interaction becomes more intense once they’re within about 1,200 miles. Hurricanes are smaller, so that threshold is smaller. But even tornadoes orbit one another in Fujiwhara-like interactions! When a storm spawns multiple tornadoes simultaneously, the twisters tend to swirl around each other in a counterclockwise fashion. In fact, that happens regularly with what’s called cyclical tornadogenesis, or the process by which rotating supercells produce successive tornadoes. A dying twister is tugged ahead of its successor, then swirled left (north) into the rain and hail where it’s stretched into oblivion. As its predecessor dissipates, the new, stout tornado matures and begins tracing its large counterclockwise path. These handoffs can happen every 15 or 20 minutes in powerhouse thunderstorms. The Fujiwhara effect can even manifest within individual tornadoes. Most tornadoes contain smaller whirlwinds called subvortices. They last a few seconds each, and whip around the parent funnel. Individual subvortices can locally enhance the parent tornado’s wind field, leading to narrow swaths of extreme destruction. That’s why one home might be obliterated while a neighboring structure escapes unscathed

What happens when a child learns that bad behavior rarely has any real consequences? 👀👀👀 All parents want well behaved children, but how many actually want to be strict and discipline them when they start crossing the lines? It can be easier to give in, ignore the behavior, or hope the child eventually grows out of it. The problem is that children are constantly learning where the boundaries are. If they discover that screaming, throwing a fit, talking back, refusing to listen, or deliberately breaking rules gets them what they want, there is very little reason for them to stop. Young children need boundaries because they are still learning self control. They need to know that when a parent says no, it actually means no. They need consistent consequences when they knowingly cross a line. That does not mean being harsh or losing your temper. Good discipline can be calm, reasonable, and firm. The goal is not to make a child afraid of their parents. It is to teach them that their choices have consequences and that other people deserve respect. There is also a difference between discipline and simply punishing a child. Discipline is about teaching. Sometimes that means taking away a privilege. Sometimes it means making a child correct what they did. Sometimes it means simply refusing to reward bad behavior with attention or a change of rules. Children who grow up with clear expectations often have a better understanding of how to behave when their parents are not around. Children who learn that every boundary can be negotiated may keep pushing until they find the limit. Parents don't have to be perfect, but they have to be willing to lead. If children are never taught where the boundaries are, how can we expect them to know when they've crossed them?

Universities and High Schools have not moved rapidly enough to guide students to have skills for the next decade. THEY HAVE FAILED. It is a massive crisis that can be averted by understanding what AI and Robotics will bring about. Solutions are knowing how to use these tools and new industries that will rise. But this situation is also on ALL OF US. No “job” is safe from founder to entry level in most industries. You and I, by what we do, will be “replaced” ultimately. What to do? AI and Robotics are tools, the next decade is owned by those who know how to use them expertly, but this is also temporary. We have to understand that what we do for “work” will change giving ultimately a greater value to those that are: Creative Flexible Always learning Willing to be wrong Love being human Love being alive Know history Covet wisdom Knowing all tech has downsides Building strong family and friends Realize many institutions have failed The first four are required for you to be able to live through this period with your sanity intact. The rest will allow you to thrive. There are no true careers at this point anymore. There are advocation and vocations which will either earn you money or give life meaning. We will learn that we are not “what we do”, just like we knew for 99% of human existence. Let that sink in. — You and I are far, far ahead of knowing this and we can do two things: 1) Laugh at the “clueless” 2) Help people understand with grace Go to Reddit if you are 1, in fact don’t follow me because you will not like this next decade and what I post. You are 2 and thank you. Even if you and I have not solved this issue, we can help people understand what is ahead and with determination and creativity bound together to solve it locally. Or human family has done this millions of times. The evidence is: you are here. The Neo Luddite movement has not even begun and it will potentially rip apart society even more than all the fashionable moment in the recent past has. These Luddites will have a good point with the wrong answers cooked up by dying academics that cling to labels, “virtues” and victim hood. It will be readymade for some governments to enter in as “big daddy” to “help us”. You will not like what they do, but you will only know when it is too late. It will include YOU “volunteering” to “leave” by 60, to “help out” CanadaPod style. “Brian, I’m 24 what do I do?”. I hope to do much more here to help. But I do know this: 1) Learn a trade or vocation because it’s valuable. It may also be free to low cost if you do it right. 2) Learn everything you can about USING AI and TRAINING YOUR AI. Your expertise will be in the top 1% for a decade. But not forever. 3) Understand Bitcoin and how it will rise while other things sink. This is a short list for now. We will know more moving forward. When you see videos like this posted below, know one thing: Many of these folks had no real family of mental and physical support. Maybe no parent or one parent. Maybe only a broke system to prepare them for—nothing. This was not their doing. Now it is not your “job” to help them, it is your survival to help them if that is what you need. See some day after the dust settles these 20 year olds will be 40 year olds and running YOUR world. And at some point you may need them more than you think you do. You will need them, as they need you now. THIS IS WHAT PAST WISDOM KNEW. The elders of the past never found the need to piss on the youth and hope for the best. THE YOUTH ARE OUR BEST, let us all find ways to change it, even if every aspect of “the system” wants us to berate them into the ground.
