Abstract. This paper shows the first volume-imaging radar that can run in any
weather, revealing the turbulent three-dimensional structure and airflow
of convective cells, rain clouds, breaking waves and deep convection
as they evolve and move. Precipitation
and clear air can be volume-imaged independently.
Birds are detected as small high-power echoes moving near horizontal, at
different speeds and directions from background wind. The volume-imaging
method could be used to create a real-time virtual-reality view of the
atmosphere, in effect making the invisible atmosphere visible in any
weather.
Key words. Meteorology and atmospheric dynamics (convective
processes, turbulence) – Radio science (instruments
and techniques)
