Geostationary Satellites
GOES satellites provide the kind
of continuous monitoring necessary for intensive data analysis.
They circle the Earth in a geosynchronous orbit, which means
they orbit the equatorial plane of the Earth at a speed matching
the Earth's rotation. This allows them to hover continuously
over one position on the surface. The geosynchronous plane is
about 35,800 km (22,300 miles) above the Earth, high enough
to allow the satellites a full-disc view of the Earth. Because
they stay above a fixed spot on the surface, they provide a
constant vigil for the atmospheric "triggers" for severe weather
conditions such as tornadoes, flash floods, hail storms, and
hurricanes. When these conditions develop the GOES satellites
are able to monitor storm development and track their movements.
GOES satellite imagery is also used to estimate rainfall during
the thunderstorms and hurricanes for flash flood warnings, as
well as estimates snowfall accumulations and overall extent
of snow cover. Such data help meteorologists issue winter storm
warnings and spring snow melt advisories. Satellite sensors
also detect ice fields and map the movements of sea and lake
ice.
