how satellite can be used in weather forecasting?

A weather satellite takes pictures of the earth and the clouds.  Forecasters use these pictures to see where there are clouds, what type of clouds, and how they move.\n\nSatellite images are also used as in-data for numerical weather predictions (= computers simulate what will happen in the atmosphere in terms of temperature, humidity, wind, etc).\n\nSatellite pictures are not sufficient to predict the weather, no matter how often you would receive them.  Forecasters also use (for instance) radar images, surface observations, soundings, and numerical weather predictions.

Google earth works really well...just have to download it....but it wont be in real time everytime you use it..it sounds like you want it for security purposes...that I guess you would need a keyhole satellite for!!!

Weather radios on the market. What kind of weather station are you looking for ?

1) We don't know the precise state of the atmosphere and oceans everywhere at a given time.\n\n2) The mathematical equations used to forecast the weather are imperfect; approximations are made.\n\n3) The forecasts are run on a grid of points, at distinct time intervals, while the atmosphere operates smoothly at all time and space scales. That means that some processes occurring in the real atmosphere "get missed" by the forecast model and have to be approximated.\n\n4) The atmosphere is a chaotic, non-linear system, so small errors at the beginning of a forecast get larger and larger, until the forecast barely resembles what the atmosphere will be like in the future at all.

Hey buddy, try out Google Desktop Search! That includes a Weather update software also.. It's really very good..

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.....................

Here is one of the best computer satellite cards. http://www.hauppauge.com/pages/products/data_nexus.html\nHere is some software to use with it.\nhttp://www.progdvb.com\nhttp://www.dvbcore.com/

I'm pretty sure there's not for live satellite feeds.   The closest you can get for free is Google Earth - software you can download for free.  Also you can go to http://maps.google.com for satellite images, or http://maps.yahoo.com.  There's an even better one that costs money, but I forgot the address.  It's something like earth view or planet view or something like that

Analysts looks for groups of storms and evidence of a low-level circulation using satellite images - especially near any preexisting Lows or easterly waves they've been tracking. Several things can be used to help them determine the strength of the circulation:\n\n* Surface and radiosonde data that happen to be nearby (not often much over the ocean).\n\n* The Dvorak techinique is used to estimate the storm's strength using satellite images alone.\n\n* Scatterometer winds using satellites.\n\n* Reconnaissance flights and dropsondes used in them (normally after a storm has formed and is named).\n\nOnce the maximum sustained wind is measured (preferably) or estimated at 39 mph or greater, the tropical cyclone is named.

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

A lot of Science and Maths goes behind such predictions. Data collected from satellites, weather balloons, planes and land based instruments is analysed for numerical patterns. These patterns are then processed and compared with findings of a particular time span when a certain amount of known rainfall occurred. In the end a forecast is issued.\n\nNowadays, the job is done by Super Computers but there still remains a large room for errors.

This is a challenging question. There are weather ships that try to measure wind speed, but of course the presence of the ship itself can produce orographic effects and produce biases. Another estimate can be made from satellite and airplane observations of cloud movement. Another technique is to fly balloons (radiosondes) up into the air column and use anemometers on the balloons to measure wind speed, or track the balloons using radio methods and try to infer wind speed from that. Dropsondes can be dropped from airplanes as well to estimate windspeed. \n\nA technique that is used from satellites and airplanes is to measure the roughness of the sea surface by boucing microwaves off it (a "scatterometer"). The windier it is, the rougher the sea surface. \n\nThere are probably other techniques that are in use or have been tried or at least considered as well\n\nProbably there is room for improvement in all of these, if you are so inclined to think about it!
