Additional weather satellites are operated by the European Space Agency. Some U.S. weather satellites are "polar orbiting", maintaining orbits roughly between the north and south poles about a14 times a day. But the satellites that capture the images you see on TV every day are called "Geostationary Operational Environmental Satellites" (GOES). These satellites maintain a fixed position above certain points on the globe, so that their sensors always watch over the same portion of the earth's surface. In this way, they can repeatedly gather images from the same area, and those images can later be played back in sequence, like a movie. In this way, the development and movement of clouds and storms can be easily monitored. Satellites don't last forever and are replaced periodically, with each new satellite carrying more and more sophisticated sensors. One reason weather forecasting has improved and continues to improve is because of the increased ability of satellites to analyze the earth's atmosphere.
