Any or all forms of water particles, whether liquid or solid, that fall from the atmosphere and reach the surface. Precipitation is a major class of hydrometeor and is distinguished from cloud and virga in that it reaches the surface.
Industry:Aviation
Any process which reduces power density in radar signals. Precipitation attenuation reduces the power density because of absorption or reflection of energy by precipitation. Range attenuation is the reduction in radar power density because of distance from the antenna. Range attenuation occurs in the outgoing beam at a rate that is proportional to 1/range2. The return signal is also attenuated at the same rate.
Industry:Aviation
Any runway or runways currently being used for takeoff or landing. When multiple runways are used, they are all considered to be active runways.
Industry:Aviation
Any stationary wave disturbance caused by a barrier in a fluid flow. In the atmosphere, when sufficient moisture is present, lee waves are evidenced by lenticular clouds on the lee side of mountain barriers. Lee waves are also called mountain waves or standing waves.
