In '79 I was in the south part of Cheyenne wy in a garage with the door open to the south I was working on cb radios The weather turned nasty and hail was blowing every direction possible I walked out and looked to gthe north the whole sky was black with 3 tunnels (big tunnels) whipping about all the way to the ground They were about a half a mile away A 1/4 mile away was our house where i left my minature dachsund I jumped into my old pickup and rushed home finally found him hiding in the water bed. I scooped him up and went out parked on a south ridge and turned the radio on. It is a sight and sound that one never forgets.. Later in Sterling I did see lightening fireballs walking up and down the tv tower guy cables.

And I have been at sea with violent weather including the north sea ne of Scotland Above the circle we hit waves that moved the forward 6" gun turret 6 inches. The seas can be the most calming and spiritual in the world but let you know how vulnerable you are when they get violent and in 120 degree weather like in the carribean you can have 10 -20 foot swells. At sea you go parrallel to the swells not across them then change the course and tack the other way..Salt water can damage and corrode electronic or any mechanical apparatus. In Norfolk one time the moon and tides were in phase which caused major flooding of inland fresh waterways..

I replaced a wiring harness under the dash of an auto trying to get it operable again we got it running but it never was right.. a nephew of mine has spent a year in  New Orleans replacing sheet rock and dry walling

The only difference between a tsumai and a nuclear blast is the nuke has radiation They are both totally devastating

If you look at a globe the outline of africa and south america matches the theory is that at one time they were one continent and separated with a shelf twist and  our continent gradually moving west..

Red sky at night sailors delight Red sky in morning sailors take warning.

Ahhhh, but do you know the explanation of that saying?

I had to google it to remember the whole theory..

Ollie,

    I suppose we are all quite small and vulnerable when up against a cataclysmic event such as a Tsunami, but ANY of these events are deadly whether it's a super-volcano, mega-tsunami, Category 5 hurricane, or hypercane, F-4,5, or the phantom 6 Tornado, Giant mudslide, wild fire out've control...Significant seismic activity such as an earthquake that measures 8 on the richter scale occuring in a densely populated area such as the CT. River valley (expected).

Anyone know the latest thought on the Bermuda Triangle "sudden storm" events ?  Has this been logically explained yet ?  Or is it just that this is a heavily navigated and flown area and events are likely ?

Here's an update on the late February sinkhole in Guatamala City.

Two concepts I don't understand are how "wind force" and "water force" are measured. IE...  We all know roughly what 80 mph means, however how a wind traveling at such a speed affects an average male trying to walk in such an occurance depends on surface area, mass, and a tiny chipmunk with less surface area will have an easier time navigating thru such a wind, etc...   Similarly what does water force mean ?  An object was attached to a Helicopter and dipped down into the cresting water over Niagra falls, the water depth was 15 inches,  and perhaps traveling at 20 mph.. the force of the water took out the helicopter..  (I think this is so, might be an urban legend for all I know),  So water speed, when discussing rapids, Tsunami, and windspeed when discussing tornadic activity, or ANY strong gust isn't just how fast a piece of paper will travel in such a gust, it's how it affects physical objects with it's force..


What are the highest winds an average sized adult male can walk in ?   stand in ?  similar could a person stand in a 6 inch deep stream of water taveling at 50 mph without getting knocked off their feet and carried off ?   These are physics concepts I have no clue of...  This is also what must be understood to know the power of such elements.

Here is some fury for you guys.. This is a hailstone from my front yard from yesterdays storms.. We had hail the size of Baseballs at my house.. I can't see that I saw that but I can tell you that when me and the kids came out of the bathroom 30 minutes after the hail fell this is what was on my front porch.. Keep in mind it had already been melting in 70 degrees for 30 minutes......

We went on umpteen dozen carribean cruises and never noticed any electronic abnormalties with radar or telemetry in that area and we did fire several missles at Rosie roads which is by Puerto Rico.. Not in the triangle.

One annomily I never could figure out our tracking radar wasnt even doppler yet we could track subs fathoms down and verify the co-ordinates with sonar. That much water plus atmospheric and weather conditions have weird effects on alot of stuff. Sea gulls have hollow bones and the cavities are small enough to be resonant with super high freqs and we could actually lock on and track birds.. We were home ported out of Villafrance which is over the hill from Nice one year We anchored out in a small harbor and I think the nearby hills were filled with iron pyrite because we couldnt lock on to weather balloons until they were at a 1000 ft or so..

At sea or in violent weather conditions can wear out the body until one has no strength left.. One of my favorite books was Hemmingways The Old Man And The Sea. And once when I was marlin fishing out of Mazatlan and sitting on the fantail and drinking Cruz Blanca beer that whole story flashed back..  The skippers mate did not speak engles yet we bonded as sailors for he knew that I was accustomed to the sea..

Wow Sharon,   We don't ever get anything the size of THAT hailstone up around here.  That must've been from quite a storm !   Bill will likely let us know what hit you folks.   I assume there was a tornado watch too that accompanied that sized hail, That was likely  considerably larger 1/2 hour prior when it fell (naturally), can you imagine what that would do to a car, or person who was out and hit by that ?    Even a house,   put a nice sized dent in the siding, or wood, smash a window, etc.  Very dangerous

Hey Ollie, Murray, and Bill-

    I think I just figured out why I have a relatively tough time grasping the concept of "wind force"...  Sometimes these principles one would hope are reasonably simple, just aren't.   Thermodynamics laws aren't something I ever learned.  Is this considered physics ?   If it is,  I've just once again had confirmed why I have a "block" in this area of science.  I can proudly say that I failed materials science the first time around, and mechanical enginerring IS NOT something I can grasp.  Not sure why, maybe I just don't like it <shrug>. Sad thing is, I love structural and civil areas of engineering.  This requires physics ability.

IE..
The Force of the Wind
The wind exerts a force on bodies moving relatively to it, and we may want to estimate the force. To find the force on a plane surface normal to the wind, we can use the impulse-momentum principle mÄv = FÄt. The amount of momentum transferred to the surface in a time interval dt is (ñV)(Vdt) per unit area, which must be equal to the pressure P times dt, or P = ñV2. This actually overestimates the pressure, so it is a useful formula for engineering purposes. The density of air at STP is ñ = 1.293 x 10-3 g/cc. For a wind of 10 m/s (33 ft/s) P = 1293 dyne/cm2 or 2.7 lb/ft2. The pressure is easily calculated for any wind velocity you wish. If the air strikes the surface at an angle è with the normal, the pressure is multiplied by cos2è.

The force on a body of projected area A is expressed as F = CAV2/2, where C is the coefficient of drag. If, as is the usual case, the flow is turbulent (Reynolds number Re = 2rV/í > 1, where 2r is the diameter of a spherical body), the body creates a turbulent wake behind it, and the force is due to the difference in pressures on front and back. This is called form drag. C is a function of the Reynolds number, and is different for bodies of different shapes. For laminar flow, at small Reynolds numbers, C = 24/Re. For a sphere at moderate Reynolds numbers, C = 0.5, approximately, and for a disc, C = 1.0. A streamlined body makes only a thin turbulent wake, and C can be as low as 0.04. These figures are good enough for estimates, but for accurate values the aerodynamical literature should be consulted.

When a nonspherical body falls freely, it orients itself for maximum C. This is easily tested by dropping light objects, such as leaves. A disc, therefore, falls so that its plane is horizontal. For such bodies, C can be taken as 1 for the purpose of estimates. This applies particularly to ice crystals in the form of plates, which is very common. The crystals falling from cirrus clouds will all have the same orientation, facilitating the creation of halos, which are the cooperative effect of many crystals (as the rainbow is of many drops). An ice crystal should fall more slowly than a droplet of the same weight, jointly due to the increased area and the orientation.

The terminal velocity of falling spheres is of some interest in meteorology, so it will be discussed here. At the terminal velocity, the drag is equal to the weight of the body, and can be found in this way. The drag is F = C(ñV2/2)A, while the weight is (ñ' - ñ)gv, where v is the volume of the body and g is the acceleration of gravity. ñ' is the density of the body, which for water is 1. This gives V2 = 2F/ñCA = (16/3)(ñ' - ñ)gr/ñ, where we have used C = 0.5, v = 4ðr3/3 and A = ðr2. The terminal velocity is V = 6.36r1/2 m/s, where r is in mm.

The Reynolds number is Re = 133r(mm)V(m/s). When this is less than about 10, the drag coefficient rises when the flow changes from turbulent to laminar, and is equal to 24/Re. With this value of C, we find a terminal velocity of V = 112.3r2 m/s, again with r in mm. The two formulas give the same terminal velocity when r = 0.147 mm, when V = 2.44 m/s and Re = 47.7. This is a reasonable choice for a dividing line between turbulent flow for larger spheres, and turbulent flow for smaller spheres. The terminal velocity does not vary smoothly through this region; when laminar flow occurs, the drag increases abruptly and the terminal velocity abruptly decreases. In turbulent flow, the terminal velocity does not vary rapidly with r, but for laminar flow it does.

(I think I'll forget about measuring water force for now)  :shock:

(This stuff is humbling, and dang,  sure can make a person feel stupid)
I'll need to stick to the basic qualitative areas of the physical sciences.  This quantitative stuff is for you "technical" folk.

Yeah there was a tornado warning and they believe that one touched down about 3 miles from my house.. It was pretty scary...It caused a lot of damage.. One of my son's was at work and his bosses car had a couple of wondows broken out by the hail...

Speaking of very large hail back in 1980 I was in a storm that had softball sized hail.. I was in a car and all the window got broken out.. I got a sprained arm from a hail stone...It was not a fun experience....

Insurance Journal;





Sharon,

    Depending on the surface that hail stone fell on, (assuming it was lawn, or a non-paved area) there likely would be a depression/indentation (or crater ) left outlining its size where & when it landed.  That ice-rock had considerable mass.

Ummm... actually, no.

That's sad. Maybe he'll pop in here and say something soon.... Yikes.

Steven, I have a new "natures fury" story for ya. Here it is April- in Oregon- and the sun is shining brightly. Not a cloud in the sky. I'm about to start throwing windows and doors open, it's so nice outside. Now WHAT kind of "freak of nature" do you think THIS is?  :no:  What has happened to our gray clouds and our daily downpour? It's just plain wierd, I tell ya:)

Charmin,

    Likely the EXACT same phenom we are experiencing here in the Atlantic Northeast.   Three days ago, 20's.

Two days ago,  65 degrees

Yesterday 75 degrees


Today,  mid-80's... (Air conditioner went on late morning in fact for the first time)


Now whether this means tomorrow will be close to 100 degrees, or a blizzard, this of course remains to be seen.   Very weird weather pattern.  While it's not uncommon to have heat on nights while AC might be turned on for awhile during a day, the nights the past few days have stayed quite warm too.

Here,   we didn't have winter until late February,  and it lasted untill Spring two days ago, and today Summer....

We are having a strange weather pattern.   This is probably fun for meteorologists, but in terms of accuracy of their forecasts, perhaps nightmarish.  When things jump around this much,  Lord only knows what's in store.

I recall years back we used to follow "The Farmers Almanac" for rough ideas as to what's to come.  I wonder if that's still around.

I don't recall whether or not the Pacific Northwest commonly get's similar and simultaneous climate conditions as we do here across the country (Atlantic NE).   We usually get very different conditions don't we ?  Due to the dip south of the Jetstream that swoops down south carrying canadian air, but doesn't dip into the states until it's closer to mid-states ?   Not sure.   I suppose this has to do with Jetstream shift.  Not sure.  This is an area I have no knowledge of.

I don't know. You'd think..... living here a big portion of my life, that I would know. Heck, I just always put on a jacket when mom said put on a jacket, and knew I could wear shorts starting the last day of school:) I never paid much mind to the weather.

It does seem to be swapping extremes awful quickly. I mean, it usually is that nice weather starts "working it's way in".... or you hear a "rainy spell" is headed our way. And it eventually changes temps little by little. But yeah, a few weeks ago, we had near 80 on a friday. Saturday morning was freezing and we got a huge amount of rain that weekend and a windstorm, it just changed drastically over night. (i know 80 degrees isn't overly hot... but here, in March, it is)
Now again, we've had a rainy spell, and yesterday and today are pretty nice outside again. I don't mind it, it's better than same o' all the time.... but I hate when it's such an EXTREME change all at once.

(go shopping for shorts and tanktops, store my sweatshirts and flannels... here comes the rain and low temps back...... dig those sweatshirts and flannels all back out, wake up to sunshine and need to throw the windows open to get a breeze going in the house)  :no:

My parents used to SWEAR by Farmers Almanac. My dad would say "Well, how do you think farmers know when to plant and when to prepare for harvest and all that, of course it's accurate". But I've never went by it myself. I think maybe I'll get one and see. It sure can't be any more off track than the local weathermen usually are, Lolll.
