dear sir,     we could not understand the artificial raining ., which method they will be used ?

G'day Siva K,\n\nThank you for your question.\n\nIt is commonly called cloud seeding. It is normally done by using aircraft to place silver iodide or dry ice into potential rain clouds to increase the amount of rain. There are two types of suitable clouds for the process - cumulus and stratus.\n\nIt is widely used in China and Australia.\n\nI have attached sources for your reference.\n\nRegards

you should always run. (that is to minimize the water that hits you.)\n\ni actually did a mathematical derivation of this problem. you can check it out at this address:\n\nhttp://www.xanga.com/phenol/332054232/item.html\n\nTo put it in a way that's more easily understood. let's assume that there are always a certain number of rain drops right infront of you. these are the rain drops that'll hit you from the front. so whether you run or walk, the total number of rain drops that'll hit you from the front is always the same. however, you're alway recieving rain from the top, and the longer you stay in the rain the more water will hit you from top. so running reduces the water you recieve from top and will minimize the total amount of water you recieve.\n\nnote that this derivation is done on idealized conditions and may not apply to all situations. (i,e. wind, umbrella, puddles...)

Overcast with a chance of rain.

nothing good, radioactive rain spread over millions of acres of land and water. waste of time and energy.\n\na class 3 hurricane has the force of 10 hiroshima bombs going off every second, one more would not matter in the disruption of the wind and rain field. \n\nbut just as an experiment it is a bad idea. in the 1960's they tried cloud seeding in the edge of hurricanes, it made them stronger and rain more.

What the heck are they doin to weather??

If you mean how can we forecast the weather, it's largely a matter of  measuring teh movement or change of wind currents, humidity, and a number of other factors.  Now, most of that is fed into a computer, and it gives aprediciton of what the weather will be over a short period of time.  Or, you could use an ancient Indian weather rock:  If it's hot, the sun is out; if it's wet, it's raining; if it's swinging, the wind is blowing...

You obviously have no concept of the energy involved in even a simple thunderstorm. Short of multiple thermo-nuclear bombs, there is no feasible way to deliver the energy necessary to match even a strong tropical depression. Oh, and then there is the problem of controlling the result. \n\nUntil scientists can predict the weather accurately, there is no way they can control it.\n\nAs to Tsunami's, these are not a weather event but rather the result of a earthquake. In the realm of large energy releases, this type of event makes the biggest hurricane seems like a hiccup.

No, it means that you should take your umbrella with you, because the humidity in the air, and the pressure system suggest it could rain.  Weather prediction isn't exact science, so basically... they never KNOW for a fact if it is raining or not... no matter what percent they give.

Woah!  Stay inside, try to have your car in an elevated area or a garage, and put sandbags near your doors if water leaks under them.  We're supposed to get crazy thunderstorms and hail this afternoon, with tons of rain, too.  Good luck!

ASOS The Automated Surface Observing Systems  uses an array of sensors to detect weather phenomena I.E.  Rain, Wind, Tempature, Lightning and other weather related information\n   Available technologies of the present day lightning detectors include: \n\na. Radio Frequency (RF) Detectors. These measure energy discharges from lightning.  They can determine the approximate distance and direction of the threat.  \n\nb. Inferometers. These are multi-station devices, much more costly than RF detectors. They measure lightning strike data more precisely. Usually they require a skilled operator.\n\n\nd. Atmospheric Field  Mill Monitors. These measure the potential gradient (voltage) changes of the earth's electric field and report changes as thresholds build to lightning breakdown values.  \n\ne. e. Optical Monitors. These can provide earlier warning as they detect cloud-to-     cloud lightning that typically precedes cloud-to-ground lightning.

I'm not completely sure, but I do know that the ring signals that the next day will be rainy. Perhaps it has something to do with an incoming front. Or a rise in humidity.

Thundershowers. It doesnt mean it will be raining thunder! It means that there will be little thunder with more rain.

No, I can't because I don't have psychic power, but I can take a guess: lots and lots of buildings on land and under the sea; electricity comes from current of the ocean; using a oxygen filter, people can swim without getting drowned; some of the animals will probably extinct; the weather is hotter, less rainy, which is assuaged by artificial rain.\nThat's all I can think of for now.

Looks Like Rain.  \n\nthe link in the source is to david dodd's online version of his book.

Actually, no one has quite gotten into the reality.  Rain is almost all rain.  But something like 99% of all precipation drops form around something called condensation nuclei.  Basically that's a fancy term to say some small particle in the air.\nThis can be dust, clay, sea salt, pollutants (leading to smog, acid rain, etc), even tiny insects... whatever's available.  Water actually takes advantage of the particle's curvature, allowing water to condense even though the air isn't 100% saturated.\nCloud seeding is an attempt to induce additional rainfall by adding more particles.  It is only marginally useful in most places.\n\nThere are also small amounts of mixed in gases (nitrogen and oxygen mainly) and any other pollutants the raindrop comes into contact with while falling through the atmosphere.\n\nBut mainly rain is just water.  Awesome stuff, too!\n\nHope I helped,\nGod bless,\nShane

Do you perhaps mean DETECTS precipitation??\n\nRADAR
