Atmosphere observation sensor applies in the technology in the plane
[introduction] at present, the foundation that involves in public atmosphere observation, sky radical, day radical in this 3 big fields, the method of atmosphere observation is complex and diversiform, wait to be able to get relevant weather data through rocket of ground weather station, radar, sounding, sounding balloon, meteorological satellite. Major business uses a plane to also be collected of atmosphere sensor and automatic data with processing system, this system can survey the scene in the flight data transmits a ground automatically, complete the main process of plane atmosphere observation thereby.
The advantage of plane observation depends on climb, cruise, drop level all can collect data.
A lot of research make clear, plane observation data conduces to the accuracy rate that raises numeric weather forecast. Current, the advantage of plane observation depends on climb, cruise, drop level all can collect data, and frequency second tall, density is big, what can raise large scale is short-term with ability of metaphase weather forecast, make up for already atmosphere explores a method to be in in the sky get ocean to mix the inadequacy of side of high-level air data.
Our country forecasts medium application to study the work in numerical value about data of plane atmosphere observation only then 2002 bottom, civil aviation undertook between Chinese atmosphere bureau and civil aviaton branch implement the collection of exploration weather data transmits an experiment, finished a data arrange decipher job, built a data to receive platform.
Current, the aerostat of 97.6 ％ above already installed our country airline automatic sensor and clearing count weather data to transport fixture as it is said, company of communication of civil aviaton data already built 170 many earth stations in the 110 many airports inside countrywide limits, use at receiving the atmosphere observation data that transmits below the plane.
The atmosphere letter in plane observation system is collected and transmit processing
We know, the flight plans to need accurate weather forecast, so that pass computation,understanding head and caudal wind are mixed the specific fuel consumption that air temperature causes. Because plane big density is in the airport to take off,descend, the atmosphere observation data that the sensor that its carry explores automatically, already became the airport to reach its the data of real time sounding of around airspace. The data of these high density, the member that make forecast can monitor the airport and element of circumjacent area atmosphere and spatio-temporal change characteristic continuously, what catch observation of a few groovy sounding to be hard to discover then is medium system of small measure weather reachs his to evolve into a trend, for accurate make draw near and short when forecast provided accurate forecast basis.
In realizing process of plane atmosphere observation, the automatic data that the plane of airline distributes stock to mature quite normally is collected and processing system, can gather the atmosphere information such as field of wind direction, wind speed, temperature, baric, wind.
For example, use navigation system of civil aviaton aircraft and airspeed system, can calculate plane photograph is mixed to the speed of the ground the air vector difference relative to the speed at the plane, obtain wind field data thereby; Measure lukewarm sensor component through platinic resistor, can obtain air temperature data; Use lade explore in cloud physics, operation of artificial influence weather is special the particle on the plane measures systematic etc airborne cloud physics explores an instrument, the diagnostic measure of the liquid state that can explore all sorts of measure in the cloud and solid state particle and chart distributing.
