How do  weather satellites help predict  and if  control or change  the weathers?
602607
Weather satellites are used to collect basic data, such as temperature and moisture levels, which allows experts to predict weather to a reasonable extent. Past attempts to control weather have been largely unsuccessful and have centered mainly in trying to create rain.

There are a lot of great sites that give basic weather predicting information.\n\nDifferences in air pressure are what causes the fronts--high and low pressure. High pressure areas generally have dry, good weather and areas of low pressure have precipitation.

Types of satellites? Well there are many ways of classifying satellites:\n\nStabilisation\nSatellites have to be stabilised so that they can always point in the direction they want to be pointed in and so that they can thrust in the right direction etc. You can have 3 axis stabilised or rotational stabilisation (where one bit spins, like the solar panels, and one bit is de-spun, like the dishes)\n\nFunction:\nMilitary, earth observation, solar observation, deep space exploration, communication (Satellite TV & cell phones) are some examples of different satellite functions\n\nOrbit:\nYou can have satellites in many different orbits. Near Earth Orbit, where it orbits at a low altitude (e.g. 200miles, time to complete 1 orbit = 90 minutes), Geostationary orbit (orbit period = 24 hours), Highly Eliptical orbit (for communications in high latitudes). Lagrange orbit (satellite stays in the same place relative to the sun&earth)\n\nYou can find out more on any of these with a simple google search on their names

HI \n      \n              YOUR QUESTION IS PLACEMENT OF SATELLITE AROUND THE EARTH. BEFORE GOING IN DETAIL YOU NEED TO UNDERSTAND GRAVITY. GRAVITY IS THE MAGNETISM OF EARTH THAT TRY TO ATTRACT ANY OBJECT NEAR THE EARTH WEATHER IT IS ON THE EARTH OR IN THE SPACE.\n       BECAUSE OF GRAVITY ONLY MOON KEEPS CIRCULATING THE EARTH.\n       \n            IN NORMAL PHYSICS RULES SAYS ANY OBJECT IN SPACE HAS ATTRACTION TOWARDS EACH OTHER, AND IT IS INVERSELY PROPORTIONAL TO THE SQUARE OF DISTANCE BETWEEN THEM.AND EQUALLY  PROPORTIONAL TO THE MASS OF THEM     \n      \n             SO NOW WHEN ANY SATELLITE IS READY TO BE LAUNCHED THEN IT WILL BE CALCULATED ACCORDING TO THEIR MASS SO THEY GET PERFECT DISTANCE. SO WITH SPACE CRAFT NOT THIS SATELLITE WOULD BEEN TAKEN TO SUITABLE DISTANCE AND BY USE OF ROBOTIC HAND IT WILL BE LAUNCHED IN IN SPACE, ONCE IT GETS IN ORBIT OPEN UPS ITS WINGS WHICH TAKES SOLAR ENERGY FOR MAKE THEIR PARTS TO BE WORKED.\n         \n           NOW OTHER RULE OF PHYSICS WILL WORK HERE THAT UNLESS AND UNTIL ANY EXTERNAL FORCE INTERACT WITH ITS MOTION NONE OF THE BODY WILL CHANGE ITS DIRECTION. SO SATELLITE KEEPS ON CIRCULATING AROUND EARTH LIKE MOON AND WORKS ON SOLAR ENERGY.

Anyone who thinks man can control the weather has no concept of the energy involved in a simple thunderstorm not to mention a tornado or hurricane. \n\nBut before you can control the weather, you need to be able to predict it. So when the weather forecasts become accurate, I'll start worrying about the government controlling.

Well, weather forcasters are much better at predicting the weather since they were 20 years ago, but even with high technology, weather is hard to predict because the atmosphere is changing every minute, tha'ts why forcasters update their forcast that often through the day.

'in real time'\nNope, not for the general public.\n\n[modified below for clarification]\nI'm guessing that you want real-time visual imagery. \n\nBut..\n\nIf you want real-time weather images, then \nhttp://www.ssec.wisc.edu/datacenter/\nhttp://wwwghcc.msfc.nasa.gov/cgi-bin/get-goes?satellite=GOES-8%20HURRICANE&overview&info=ir\n\nand, here's additional source from a google \nhttp://www.google.com/search?hl=en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=%22real+time%22+%22satellite+image%22&spell=1

The world's space programmes have paid for themselves many times over in communications satellites, resource satellites to give advance warning of environmental disasters, weather satellites and they're about to pay off with manufacturing in microgravity.  And now the pure scientific research element of the space programmes has given us a more plausible account of how we came to be here than any religious fairy stories, there's a real chance that the world's religions will lose their appeal, and we'll have less reason to kill each other.  Before weather satellites, the first you knew of a tropical storm was when it hit you.

chek out the source for more info\n\nMETSAT/Kalpana series\nMETSAT or Meteorological Satellite, is the first satellite built by ISRO to provide meteorological information and data. In 2003, METSAT was renamed as Kalpana in honour of the late astronaut Kalpana Chawla. METSAT 2/Kalpana 2 is expected to be launched by 2007.\n\nIRS series\n\nThe IRS series provide remote sensing services and are composed of the 1 (A, B,C, D). The future versions are named based on their area of application including OceanSat, CartoSat, ResourceSat. Some of the satellites have alternate designations based on the launch number and vehicle (P series for PSLV). ISRO and the Department of Space (India) have jointly formed Antrix Corp Ltd, for promoting and marketing IRS satellites\n\n\nINSAT series\n\nThe Insat series of satellites include the 1 (A, B,C, D), 2 (A, B,C, D/DT), 3 (A, B,C, D,E) and 4 (A) series. They provide Communication and Television relay services all over India. Most of these satellites were launched by the Arianespace for ISRO, the latest being INSAT 4A. ISRO also plans to launch the next generation of INSAT satellities, INSAT 4B and 4C, by 2005-06.[

satellites.\n\nfor sure

I guess it might depend on what makes a satellite important.  The GOES (Geosynchronous Orbiting Earth Satellite) series of satellites continuously monitor our weather and take various pictures of clouds for weather forecasters to use.   The GPS constellation of satellites provides useful (perhaps even critical) positioning information to millions of users.  SARSAT is used to pick up distress beacons from mariners and aviators.   Galaxy 5 is a very widely used telecommunications satellite for the mainstream media.\n\nMany "important" satellites already have back-ups in orbit, ready to be moved into position should its predecessor fail.  Also in the case of DirecTV and XM radio, they have a spare or two in orbit as well since they would stand to lose a very large portion of their subscribers should they have an extended outage...sort of an insurance policy.\n\nSatellites are used for many different purposes, virtually all of them important since it costs so much money to launch them into orbit.

I think you are talking about the 'Butterfly Effect' in weather forecasting.   With all the wonderful computers they have to help to forecast the weater, one of the staff was sitting in his garden when a butterfly flew past him.  He suddenly realised that the air movement caused by the wings can cause air movement which can increase over time, enough to cause a major storm in another part of the world.....................

Barometers measure air pressure. \n\nAt a given location a storm is generally anticipated when the barometer is falling rapidly; when the barometer is rising, fair weather may usually be expected.\n\nYou would expect the desert to have the highest reading.

There is an interactive satellite weather map at www.weather.com.

There are many, many types of weather instruments. A complete list would be very extensive, but here are a few instruments to investigate:\n\nAnemoscope, anemometer, hygrometer, barometer,rain gauge, thermometer, sling psychometer, radiosonde, rocketsonde, theodolite, weather satellites, doppler radar, various lightning instruments like time of arrival and magnetic direction sensors, lightning imaging sensor (space-based), electric field mills, Gerdien conductivity probes, pyranometer (actinometer), evaporimeter (atmometer), and so on.

Weather is a chaotic system; predicting it is difficult and only as accurate as the input data. Most TV and newspaper weather is very generalized - mass media is just entertainment and advertising, so you really shouldn't expect more than that. Military and agricultural forecasts are much more accurate but aren't free. It's been mathematically demonstrated that, even with the very best data possible, weather forecasts will never, ever be able to predict much more than 14 days out. Beyond that, things are just too chaotic.\n\nFor an example of truly accurate non-media weather forecasts, checkout SkyBit:\nhttp://www.skybit.com/cgi-bin/nav.cgi

Not sure about forecast, but Kestrel makes some amazing anemometers (wind meters), some with barometers and altimeters built in.
