Use of satelite technology for weather

History[ edit ] The first television image of Earth from space from the TIROS-1 weather satellite in A mosaic of photographs of the United States from the ESSA-9 weather satellite, taken on June 26, As early asthe idea of cameras in orbit to observe the weather was being developed. This was due to sparse data observation coverage and the expense of using cloud cameras on rockets. Some of these channels include: Even wind can be determined by cloud patterns, alignments and movement from successive photos.

July 08 Different methods include using satellites and radar, and reconnaissance aircraft. Observations from across the Caribbean also greatly assist in tracking tropical cyclones.

Satellites Prior to the technology used to develop and launch satellites, it was difficult for meteorologists to determine just where tropical cyclones were forming.


They relied on ship and tropical island weather observations and coastal radars. Satellite images are very important to forecasters because by putting into motion several hours of satellite pictures, they can gather information about the track and development of the tropical cyclone.

Doppler Radar Doppler radar can detect rain associated with tropical cyclones. The newest generation of Doppler radar provides forecasters with improved data about rainfall intensity, the movement of tropical cyclones, tornado activity that can accompany a tropical cyclone, and estimates of wind speed within a tropical cyclone.

Reconnaissance Aircraft Development of both radar and technologically advanced military aircraft made it possible to gather data in a new way. Today, reconnaissance aircraft are still actively used to gather tropical cyclone information, including pressure, the eye location, wind speeds within a nautical mile radius of the eye, and storm size.

They fly into a storm as low as possible to observe conditions that would affect the coastline when the storm hits, between 1, to 10, feet. Some information is received from dropsondes dropped into a tropical cyclone. A dropsonde is a radio-like instrument that records wind speed and direction, air pressure, air temperature, and altitude of these qualities.

AOC also provides aerial support of coastal and aeronautical charting, as well as aerial surveys for hydrologic research and marine mammal population prediction.

Observations Before technology provided meteorologists with radar and satellite imagery to track hurricanes, sketchy information made it difficult to know where tropical cyclones would make landfall, increasing the probability that the public would be poorly warned or unwarned altogether.

Formal installation of a national hurricane warning system was initiated by the U. Weather Bureau just before the turn of the 20th century. Early information was provided through manned weather stations in the West Indies, Cuba, and Mexico. These stations relayed local tropical weather information throughout hurricane season.

Although data gathered at these locations provided useful information about tropical cyclone intensity, stations did not provide enough information to determine where storms might head. As ships became equipped with radios, they became actively involved in providing the U.

Weather Bureau with tropical cyclone observations. Although data buoys are used for more than just predicting and monitoring tropical cyclones, they do provide very valuable information during hurricane season.

A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.

Communications satellites are used for television, telephone, radio, internet, and military applications. There are over 2, communications satellites. penetrate fog, rain, snow, dust, and inclement weather.

The satellite orbit is arranged in six orbital planes so that at any given time, from any vantage point on the earth, a minimum of five satellites are visible in the sky to any use r, anywhere in the world.
