Satellites above the atmosphere can get a clear, big picture of Earth's cloud formations. By analysing these cloud patterns, meteorologists can forecast how these clouds will change and move, and predict the weather, be it rain or shine, for many areas. For example, hurricanes can be easily spotted from satellites but not easily spotted from ground due to its size, and thus satellites come in very helpful. Also, infra-red satellite forecasting can also determine the temperatures in different areas on Earth's surface, which aids meteorologists in finding out cloud heights, cloud types, water cycles and sea surface termperatures (an important factor in the formation of hurricanes).
Answer: It's not the satellites themselves that forecast the weather; but rather the instruments that are placed onto weather satellites. Weather satellites carry instruments that scan the Earth to form images. These instruments usually have a small telescope or antenna, a scanning mechanism, and one or more detectors that detect either visible, infrared, or microwave radiation. These measurements are in the form of electrical voltages that are digitized, and then transmitted to receiving stations on the ground.
Almost all weather satellites are put into one of two kinds of orbits around the Earth. One is called a "geostationary" orbit, with the satellite positioned at a very high altitude (about 22,500 miles) orbiting over the equator. This altitude is chosen so that it takes the satellite 24 hours to orbit the earth once, which is also the rotational rate of the earth itself. A geostationary orbit allows a satellite to appear to be fixed over a single and non-moveable position over the equator. This type of geostationary satellite is what produces the cloud animations that you see on TV, and can take images as frequently as every minute or so. It also provides Meteorologists with other data allowing them to predict short and long-term weather forecasts. The other orbit type is called "polar", where the satellite is put into a relatively low altitude orbit (around 500 miles) that carries the satellite near the North Pole and the South Pole. Unlike the geostationary orbit, the polar orbit allows complete Earth coverage as the Earth turns beneath it. These orbits are usually "sun-synchronous", allowing the satellite to measure the same location on the Earth twice each day, and at the same local solar time.
Radio waves prefer to travel straight ahead, which makes it difficult to get them across large distances because of the curvature of the Earth. With satellites you shoot the radio signal up in a straight line, but at an angle, and then have the satellite send it back down at another angle. That way you can get a radio signal to go beyond the horizon.
Weather forecast can also be helped by having a satellite looking down on the Earth, so you can see storms and clouds moving before they are overhead.
they can take highly accurate pictures and give us information that we might not be able to get while on earth
they tell the mapmakers where physical features are so they can make maps.
Satallite images tell you the temperature and the chance of rain ect...
Photographs of the earth and space and sky :)
weather satelite is used to monitor the weather
In 1707, the first satellite was built by Morgan Fisalt.
Many photographic images were taken from the edge of space as both the USSR and US launched captured German V-2 rockets after World War 2. One of the first, showing the curve of the Earth, was taken on October 24, 1946. The first photo taken by an orbital satellite was by Explorer VI in 1959, showing a section of the Pacific Ocean. It was a black-and-white image with very poor detail, but subsequent images (many of them classified) had considerably better enhancement.
The Soviet Union launched the Sputnik satellite.
The Explorer but it wasnt a rocket, it was a satellite
There are a number of these floating about above us. Many are country specific as they are set to maintain geometry above a given country. However, most countries use information from each others equipment to estimate potential weather changes from around the world.The key ones areNASAGHCCNOAA - USASAT24 - This is Europe'sMany of the meteorological services are also web based for those with greater interest

Satellite tell us if there is a natural disaster happening.
A weather geostation is a satellite that orbits around the Earth. These satellites observe cloud patterns that allow us to more accurately predict the weather.

to take images of the earth and send it to google earth to show us t.v shows
they can tell us the weather like if it will rain and you can tell what wiil probbally happen before it occurs.
Excellent question! It doesn't tell us much.
There are a large number of satellites' launched from a hand full of countries. If you could tell us which satellite you have in mind I sure you will get an answer.
The climate tells you what type of weather to expect, therefore how to fill your wardrobe. The weather tells you what you must wear each day.
It gives us information on how the meteorologists anticipate the weather to be like the following few days, weeks, even in some cases months.
a weather map shows the locations of the fronts and pressures and also their locations...
Google Earth is an application which allows us to see satellite and plane images of the Earth. It works like a high resolution virtual globus.
