I just watched this beautiful video about resonance frequencies and saw a pattern (the pattern at 1:25) , that reminded me of the pole storms on jupiter: Image Credit: NASA/JPL-Caltech/SwRI/ASI/INAF/JIRA Could it be that some resonance frequencies on the pole of Jupiter are the reason why...

This is what I've been working on this summer; a storm shelter. To keep the deer off, I put two 10' dog kennels around it. front: back: electrical service with motion detector flood lights:

Hi, I’m looking for ideas and guidance (maybe even formulas?) on making an on-planet situation match a hypothetical solar system. It’s for a fantasy role-playing, but the sentient species must necessarily care (and believably calculate) aspects about their solar system. (However, because it’s...

Hi guys, not sure if anyone can help me but I'm having a bit of an issue with creating a storm hydrograph from a 60 min unit hydrograph that is in 5 minute intervals. I've lagged the unit hydrograph by 60 minutes each net rainfall block while multiplying the respective net rainfall to the...

This year's Alpha Monocerotid shower could produce a brief (15-45 minutes) burst of meteors at near storm levels. The burst is predicted to be centered around 4:50 UCT on November 22. Intense Meteor Outburst Expected from the Alpha Monocerotids Likely alpha Monocerotids (AMO#246) outburst on...

While The martian written by Andy Weir is a really hard stuff, but the effects of the storm at the beginning arent. But i wonder could a real solar/sandstorm actually help a prison break on Mars (from a remote penal colony)? Could it mask tracks in the dust? Could it create enough interference...

A traveler visits a location (or doesn't!) ##x## light years away at fractional [EDITED] speed ##v## and instantly returns at the same speed. After this her clock has progressed by ## \frac {2 x} {v} \sqrt {1 - v^2}## years. [EDITED] That really is all there is to be said. If the poster...

Oh well. Not working right for me.

Homework Statement If you were standing in a puddle. Would it be safer to spill sugar or salt in the puddle during an electrical storm? I know that salt water conducts electricity better than sugar water. 2. The attempt at a solution I understand that the salt puddle will conduct electricity...

Here is a scenario to further explain. Let's say I am traveling inside of a submarine. I travel within a depth of 100 to 600 feet deep or 4 to 19 atmospheres. How would I and my submarine be affected if there were a hurricane, tsunami, or hurricane above the ocean. Furthermore, does the...

I was surprised at the number of people thinking they should "ride out the storm" when Hurricane Mathew moved up the coast. They are assuming that because they've been in a cat 1 or 2 that a 3 or 4 is nothing to worry about. I was trying to explain to someone that force is not linier with...

Homework Statement During a thunder storm, movement of water molecules within clouds creates friction which causes the bottom of the clouds to become negatively charged. This means that the bottom of the cloud and the ground begin to act like parallel plates. Once the electric field between the...

Mid Saturday morning and the radar was telling the story, a large and long storm front line was stretching across SE Australia and was very lightning active. Said to my wife, Cindy, pack an overnite bag, we're going stormchasing and probably won't be home till Sunday nite. 300km or so of...

Would a water pump for pressure be required for a submarine outfall for storm water drainage ? Diameter of pipe 2 meters Gradient 50 Horizontal distance from shore to outfall 200 meters depth about 16 meters, sine 50 Or would the pressure from gravity gradient be sufficient to overcome...

Once during a severe hail storm (it lasted a few minutes and looked like it had snowed everywhere), my friend starting jumping around as if something was burning him, and he pulled 2 AA batteries out of his pocket and threw them outside. They were really hot and quickly melted a hole in the...

Hi all has a particularly nasty storm over the Sydney city area last nite trees down, building damaged, this morning still many homes without power a couple of lightning shots from home ... cheers Dave

Another big storm heading towards home yesterday this tiny 800x600 size doesn't do it justice Dave

hi guys and gals been a wild Monday and Tuesday here in the Sydney, Australia region 2 evenings of wild weather first on Monday was a large thunderstorm storm that came in from the west bringing intense lightning, rain and hail Tuesday nite saw an intense low form over the region. This brought...

A region of Venezuela has a high incidence of recurrent thunderstorm activity. It is apparently a unique set of conditions - a lake surrounded by mountains, where winds blow in from the ocean, and the warm moist air combined with moisture from evaporation from the lake interacts with cooler...

This question is a variation on another question I asked recently. Suppose you were in a box made from a perfectly insulating material, and a thunderstorm was raging all around you. Would the box offer you any protection from lightning strikes? I think it would, because there would be no...

A new meteor shower will light up the sky next week in the northern hemisphere. Comet 209P/Linear is forcast by some to produce 200+ events per hour hour overnight on May 23/24. Incoming will originate from Camelopardalis, a circumpolar constellation (so it will be "up all night!")...

I'm in a 10 year old apt building. I really want to take a shower, but it's a lightning show out there. Is it a myth that you can get electrocuted taking a shower during a thunder storm?

Hi! I'm really excited about recent APoD picture, which shows Cassini's photo of a gigantic storm on Saturn's north pole. They also have an animation! I can't wait for a colour picture and videos. Meanwhile, since I still didn't state the purpose of this thread, what are the inner vortex...

Hi all, I have a question regarding geomagnetic storms: --why always they affects the Northern Hemisphere? Or did i got this idea wrongly? Thanks

A large storm has been studied since December 2010. New research indicates the storm is stronger than first thought. Associated with the storm is a huge volume of ethylene, with an amount roughly 100 times through possible on Saturn. The source of the ethylene is unknown. NASA's...

Q1: What is the percent uncertainty in the volume of a spherical beach ball whose radius is r = 3.85 plus or minus 0.06 m? I found the volume of the original sphere, as well as one with a radius of 3.91. I then subtracted the volumes to find the difference between the two, divided that by the...

So i was walking along carefree as you like when i came to a sudden stop, i noted that my right foot had wedged in a storm drain cover, no matter how i tried i could not get it free, i decided the only option was to walk 3/4 mile to the industrial estate with the cover attached to my right foot...

A suburban street receives storm water runoff at rate of 2.0 L/m-s (on each side). The street has a slope of .8 percent and a cross slope of 2 percent; n = .013. If the street is 10 m wide and can be totally covered by water (depth = 0 at the midpoint), what is the max distance between inlets...

I am planning on building an above ground storm shelter that will be 16' x 16' by 8'. The footers will be 24" W by 12" D with 4-#4 rebar. Insulated Concrete Forms (ICFs) will be used for the walls then a 5" floor slab. Concrete space of the ICFs is 6.5" or 8" or 10" defending on someones...

How would the intense light from a massive thunderous lightning storm compare against regular daily sunshine in terms of the electrical current generated from a solar panel array? Just curious.

Easy question Have a 5ft x 5ft x 5ft structure made from 3/8 carbon steel AISI 1018 I think What is the max load this thing can take? What's the formula? Stress=F/A F=Stress*A? Do I use the Modulus of Rigidity? Elasticity? Where can I find these values? thanks

Did this affect any of our members? http://www.weather.com/outlook/videos/time-lapse-amazing-phoenix-dust-storm-21209

Maybe it's time I unplugged my laptop and went inside... [edit] Ooh. Here comes the lightning. And the wind. Shoulda knowd better than to light up a Churchill Wide. I'll be out here all night...

Here are a few pictures showing what the most recent storm did to the western area of Lake Tahoe: Below is a picture of the county-maintained road leading to my father's house. The next two are of the private road on which he lives. This is a picture of the front of his house. I grew-up...

Yo. As many of you know, the solar sunspot cycle is scheduled to peak again around 2012-2013. With it will come geomagnetic storms that will once again stress our electrical infrastructure. I was wondering: what sort of strategies do we have to mitigate against this threat? Do we just...

Hi all: I have been puzzled by a very simple experiment I did lately. I found there exists a temperature gradient in a cup of saturated salt water--the bottom is about 0.5 Celsius warmer than the top. That is after the solution has been left intact for more than 100 hours. There is no such...

I just discovered about solar storm named "Carrington Event"; I'd like to know how such a solar storm could affect my PC today. I found some publications: http://www.bu.edu/csp/EMMREM/papers/carrington.pdf...

We got some cool weather today along with some scattered showers. My wife was sitting there in deep concentration so I asked her what she was thinking. She said she was counting the seconds between the lighting flash and the thunder. She said that the light gets here much faster than the sound...

Hello, I've been trying to figure out the shape of the magnetic field that would accompany the movement of electrons in the ground moving towards the center of the thunderstorm. In a perfect world where the electron distribution is even in the ground and where the Earth consists of like...

Homework Statement The navigator of an airplane plans a flight from one airport to another 1200km away, in a direction 30 degrees east of north. The weather office informs him of a prevailing wind from the west, of 80km/h. The pilot wants to maintain an air speed of 300km/h. What heading...

I woke up this morning and the light was freaky! Everything seemed orange. Outside, the sky is pale orange, like fog but the wrong color. Trees a few houses across are fading into the orange ... we've got a dust storm. I live in Newcastle, a bit north of Sydney. This storm came up last night...

Homework Statement A certain storm cloud has a potential of 1.50 x 10^8 V relative to a tree. If, during a lightning storm, 50.0 C of charge is transferred through this potential difference and 1.00% of the energy is absorbed by the tree, how much sap in the tree can be boiled away? Model...

I need some help dealing with storm water. I'm trying to get a site plan approved and the township engineer wants to see "calculations in the form of a storm water management brief to indicate how post development floes will be managed such that they do not exceed pre development flows for a...

I am pretty sure ya'll heard about the Solar storm that is going to happen around the year 2012 and scientist predicts that its going to wipe out all communication sources like the satellites, gps etc...So if the prediction turns out to be true i wonder how we are going to rebuild all the...
