What technology can be used to predict hurricanes?

Answer 1

Cyclones are measured almost entirely by satellites (although at times, especially near the United States, they are sampled directly by planes that fly into them), which look down at the earth and detect different types of radiation. They are also measured by networks of automated buoys in the ocean, where available. Most of these sensors simply measure the radiation they receive (called "passive sensors") while some "active" sensors send a beam of radiation at a particular wavelength down towards the earth and wait for a response.

Passive sensors include infrared, visible, and microwave. Infrared generally measures heat, often of the cloud tops of the cyclone (which indicates how high the clouds are reaching and is an indication of its strength), while visible sensors are essentially like taking a picture from space, which serve a variety of uses. Microwave sensors can be used to take profiles of the atmosphere at some wavelengths, infer wind speed, heat, and several other variables.

Note: Satellites are the platforms on which sensors are mounted. There are often many sensors mounted on each satellite that is launched. It is not the satellite itself that takes measurements but its sensors, which are often designed to do very different things. However, the satellite is not simply a static platform, but a complex machine that needs to be able to do a variety of things as well as communicate with scientists in order to keep it properly calibrated, troubleshoot problems, and otherwise keep it well maintained and in good working condition.

Answer 2

Cyclones are detected by various means. Most often they are detected by satellites. When they occur over land as mid latitude cyclones they can be detected by ground based instruments such as anemometers, barometers, and radar.

Answer 3

Satellite imagery and readings from buoys at sea report the present weather conditions. This information is entered into computerized forecast models, which try to predict that the weather, including the hurricane, will do.

Answer 4

Different technologies are used for different disasters. Hurricanes are monitored primarily with satellites. Tornadoes are tracked with Doppler radar. Earthquakes are detected with seismometers.

Answer 5

Hurricanes are usually studied and detected by satellites.

Answer 6

They use the hurricane tracker otherwise they use satellites
