more relations between grid system and atmospheric discharges

Other than direct discharges from lightning, fluctuations in the magnetic field can generate currents in the electrical grid.  This happens as a result of solar activity such as solar wind and flares bombarding the Earth's magnetic field causing it to flex.\n\nLong distance transmission lines are especially vulnerable to this as their length is enough to act as a generator from the magnetic changes.  Grids can shut down and transformers have been melted  due to power surges generated by strong solar storms.

Maybe it has something to do with grounding. If a ship is in the ocean and not touch anything then there is no reason for the current to go up right?

Negative x value, because its a two dimensional grid so theres no third value. Y value will be unknowns since you dont give any info with respect to the y value. I believe this is correct.

I normally hate referring people to wikipedia articles, since it is so often inaccurate, but this one is quite good (link is below).  If you scroll down, there is a table that gives just what you're looking for.\n\n2x2 grid: 288 possible solutions\n3x3 grid: 6.7*10^21 possible solutions!

What has that to do with chemistry at all?  Try asking a meterologist.

Numerical calculation of unsteady flow is now a days very much possible through CFD( computational fluid dynamics) based softwares.The power of computation is so much enhanced that any fluid problem right from generalised Navier- Stokes equation can be solved easily. The various atmospheric and oceanic activity are observed and solved continuosly.

In a storm cloud, the moving air makes tiny water droplets and ice rub together so they become charged with static electricity. The positive electrical charges float up near the top of the cloud and the larger ones, with negative charges, stay near the bottom. This separation of electrical charges is very unstable and lightning is the way the charges are equalized or become balanced. \n\n\nWhat you need?\n\nA large iron or steel pot (not aluminum) with a plastic handle. \nRubber gloves. \nAn iron or steel fork. \nA plastic sheet (a dry-cleaner garment bag is good source). \n\nWhat to do..\n\nTape the plastic sheet to a table top.\n\nPut on the rubber gloves.\n\nDarken the room as much as possible.\n\nHold the large iron pot or pan by its insulating handle and rub the pan vigorously to and fro on the plastic sheet. \n\nHolding the fork firmly in the other hand, bring its prongs slowly near the rim. When the gap between pot and fork is small, a tiny spark should jump across (A darker room will help you see the spark more clearly).\n \nWhat you will Discover\nIt is as though the pan is the thundercloud, the fork is the lighting rod and you are the Earth's surface.\n\nPlease note: The humidity in the air can affect static electricity. If the air is damp, such as during the winter, then this experiment may not work.

It could be the grid of the earth, (latitude and longitude) the equator is the x-axis. and so on

There is a formula; I won't try to reproduce it here, but will instead include a link to the chart (which includes the formula) on the web site for the National Weather Service.  They have a good explanation of how it works.

i would think that the radiation from the freqs listed above should all cause excite the water molecules in the same way but to differing extents. that's a very good question; i think i'll research it.

San Francisco is not really a grid based city, although parts do conform to the grid system.\n\nBut to my knowledge most other US cities are in a grid pattern

A lot of wind current is caused by temperature differentials between two or more areas.  The earth's rotation is also responsible for currents and jet streams.  I had a porfessor tell me that the same wind that is blowing now is the same wind that has been blowing for 4 billion years.

I don't know if this what you are looking for, but here is a page which gives many types of meteorological equations.\n\nhttp://members.aol.com/Accustiver/wxworld_calc.html

air naturally comes from high pressure fronts to low pressure fronts\n\nalso if you look at weather maps those wierd looking squiggly lines \nthe closer together they are the higher wind speed you'll have

C\nTotal discharge of a (river) system is determined by its  total volume dividd by a time constant.  Just as a car has a speed (miles per hour), the discharge of a river has a volume per second (or day, or year, etc.), which measured in scientific units is cubic meters per second (m^3*s^-1). Thus, C is the closest answer, although it omits the needed time interval to describe a total flow.

D\nThe grid initiall attracts electrons from the anode because it it psitively charged in relation to the anode. By varying the charge on the grid you can control the electron flow. As the electrons near the approach the grid they are attracted to the more positive charge on the cathode and most continue through the grid to the cathode. A small number flow through the grid. The number attracted by the cathode divided by the number attracted by the grid gives you the gain of the triode it is when used as amplifier. It operates like a bipolar junction transistor

Let me answer this way:  The static charge built up between the clouds and earth (ground) cause the air between to become ionized (lightening) causing a discharge of (usually) millions of amperes of current, neutralizing (minimizing) the charge.\n   And as you know, an efficient arrestor is designed to prevent any great voltage rise during the discharge.
