Я вроде достаточно ясно написал что турбулентность (сильная, слабая бывает постоянно, но это - ерунда) в ясном небе при отсутствии частиц которые видит метеорадар - штука редкая.И "видеть" ее можно заранее, глядя на метеокарты.
How does a weather radar differ from other radars
The weather radars
use microwaves with a wavelenghts usually from 3 to 10 centimeters so they can detect particles of clouds and precipitation, i.e. from small drops to large hail particles. Other reflections are removed by special algorithms as unwanted targets. The effective radius of measurement varies from 40 km to 300 km from radar site.
Marshall and, the student of doctorate, Walter Palmer well are met by their work on the size drops and its distribution in average latitudes rain that determine the relation rain - Reflectivity to the radar (relation Z-R)
*En Great Britain: they continued the studies of landlords of " echoes of radar and tiempo" (rains estratiformas, convective clouds, etc.) and experiments evaluating the potential of different 10 wavelengths from 1 from cm
The wavelengths from 1 to 10 cm are approximately ten times the diameter of gotitas of water or interest ice particles, due to Dispersion of Rayleigh that happens to those frequencies. This means that it leaves from the energy of each pulse bounces in those small particles, returning in the direction of the radar station.
The shorter wavelengths are used even tinier particles usefully, but the signal more quickly is attenuated. Thus the radar of 1 DM in Band S is preferred but C band is more expensive than the system of 5 cm in . The radar of 3 cm in X band r is only used for intentions in very short distances, and the meteo radar of 1 cm in Ka Band is only used for studies in phenomena of small particles like fog.
Unlike the flight radar, the meteo radar has a numerous target in volume, beam of the radar: \, {h r2 \ theta2} (wide h of the pulse, r distances to the radar and \ wide Theta of beam).
