I always grew up wondering what exactly caused lightning, thunderstorms and rains. High school physics later explained and taught me the reasons, facts and theories behind this exciting part of many wonders that nature has created. In fact it so happens that there is an Indian legend which explains the fact that every thunder and lightning caused is in fact a chariot move of the great Pandava warrior Arjuna who is refered to as Falguna when it comes to sky. 



Coming to the aspect of Ball lightning, scientific data is of limited availability to explain fully about this interesting phenomenon. Its occurrence being irregular and of considerably less frequency to have data in place is a great challenge for the scientific fraternity to come to fully conclusive study. Though a lot of information and data available so far has been greatly derived from public reporting of the occurrence, there has been some studies that have produced meaningful insights into this.


How is  Ball lightning formed?

Scientists have long attempted to produce ball lightning in laboratory experiments. While some experiments have produced effects that are visually similar to reports of natural ball lightning, it has not yet been determined whether there is any relationNikola Tesla was reportedly able to produce artificially 1.5" (3.8 cm) balls and conducted some demonstrations of his ability, but he was really interested in higher voltages and powers, and remote transmission of power, so the balls he made were just a curiosity. In summary, Ball lightning is a natural phenomenon, or debatably, a pseudoscientific theory. It is sometimes associated with thunderstorms. It takes the form of a long-lived, glowing, floating object, as opposed to the short-lived arcing between two points commonly associated with  lightning.


A popular hypothesis is that ball lightning is a highly ionized plasma contained by self-generated magnetic fields,  a plasmoid. This hypothesis is not initially credible. If the gas is highly ionized, and if it is near thermodynamic equilibrium, then it must be very hot. Since it must be in pressure equilibrium with the surrounding air, it will be much lighter and hence float up rapidly. Magnetic fields, if present, might provide the plasmoid's coherence, but will not reduce this buoyancy. In addition a hot plasma cannot persist for long, because of recombination and heat conduction.


There are a few more set of theories and hypothesis surrounding this interesting phenomena that surely makes it an interesting area. But it might take  more research to exactly pinpoint the reason behind the ball lightning phenomenon. I definitely would like to experience ball lightning to know more and see what ball lightning looks like.


Austin and Kelly each threw punches in the ensuing philadelphia phillies jersers blue ervin santana authentic jersers fracas, prompting their ejections.
Yankees third-base coach Phil Nevin and reliever Tommy Kahnle were also tossed; Nevin said that he had been jawing at the Red Sox's dugout, while Kahnle blue ervin santana authentic jersers said he was incensed after having been pushed by an umpire.
Kelly claimed the pitch had been an inside fastball that got away.
He left the field with his uniform jersey torn and spots of blood on his neck, while Austin sported a bloody lip.
"I was ready to defend myself," said Kelly.wholesale baseball jersers
"Someone comes in my property in my backyard? I have two dogs.
Ready to come on my property and I'm being attacked, then I'm ready to defend myself."
Aaron Judge had sprinted to the center of the pile, where he attempted to play peacemaker, pulling Kelly off Austin.
"I saw Kelly was on top of Tyler after he tried to tackle him, so my job was just to get Kelly up atlanta braves jersers and get him off," Judge said.
"No one ever likes getting hit with 98 to the back.
Everybody was pretty upset about it."
Cameras also captured Austin landing a punch on the head of Red Sox third-base coach Carlos Febles.
Austin acknowledged that he had thrown punches.
"I'm just trying to defend myself, man.
That's all that was," Austin said.
Tempers initially flared in the third inning, when Austin slid hard into second washington nationals jersers base on a Tyler Wade fielder's choice, his spikes connecting with Boston shortstop los angeles angels oakland athletics jersers of anaheim jersers Brock Holt.
Words were exchanged between Austin and Holt, which prompted the bullpens and miami marlins jersers benches to empty.
"I probably said something I shouldn't have to start the whole thing," Holt said.
"I'm sorry for that.
I just wanted him to know it was a bad slide.
I think everyone on the field knows that it was."
Replays showed that Austin miami marlins jersers had his left foot pointing up as he slid into Holt's right foot, with third baseman Rafael Devers having fielded Wade's bunt swiftly.
Holt said that his right calf was sliced by Austin's spikes, but Austin maintained that it was a fine play.
"I felt like my slide into second base was a clean slide," Austin said.
"I play the chicago white sox jersers los angeles angels of anaheim jersers game hard.
I thought there was absolutely nothing wrong with that slide.
I had no thought that they were going to throw at me."
That situation was diffused quickly.
Heath Hembree struck out Austin in the fifth inning, and with the Yankees leading by four runs, Kelly opened their seventh-inning showdown with a slider that went for a chicago white sox jersers swinging strike.
"You don't need to drill him for that [slide]," Giancarlo Stanton said, "and if you're going to do it, do it on the first pitch."
The next pitch was a high and inside fastball, and Austin said he considered that it had been a purpose pitch.
"After that pitch, it had crossed my mind, but I thought it was over after that," Austin said.
"He missed with the first one.
Once that happens, it's kind of over."
Kelly followed with a slider that missed the strike zone, and Austin was plunked by the 2-1 offering, discarding his batting helmet and tumbling toward Kelly onto the infield grass.
"The kid that charged the mound, he had his reasons," Red Sox manager Alex Cora said.
"But if you take a look at the game, we're coming back and we're short on pitching.
I don't know.
You've just got to kansas city royals jersers pay attention to the game and you judge by yourself."

I was a witness to a "ball lightning" on July 25, 2011. Two days ago I was on my couch leaning agaist the window looking outside, it had been raining finally all day, while talking on the phone. I had just hung up the phone when I saw a flash of yellow out the corner of my eye. Hovering over our grill on the deck was a yellow/white glowing circle- hoola hoop in size.....solid, I could not see through it. It disappeared and another ball appeared and then disappeared. Less than 5 seconds later I heard 2 large booms....more like an explosion or a loud fire craker sound. I looked up in the sky and thought to my self that is some storm. Later I attempted to tell my husband what I had seen and he said it sounded like a BL, he saw a show about them on the weather channel. It was something I could barely get my mind around, totally out of my realm of understanding!!! Amazing! My house is 2 stories and I am pretty close to the deck, I could almost jump to it, it was that close!! I will never forget this1

Very interesting.. thanks for the info. Never heard about it until the recent Earthquake and Tsumnai in Japan
