“…Typically in the British Isles these bands are preceded by a strong low-level jet stream, with winds of 25 m s-1 or more within a kilometre or so of the surface. Figure 7(c) shows an almost two-dimensional example of what we refer to as line convection; more often, this kind of convection is broken into line elements (James and Browning 1978).…”

Radar has been used by meteorologists for 30 years or so but it is only during the latter half of this period that the full measure of its versatility has come to be recognised. Operationally important techniques have been or are being developed to identify and track severe storms, to provide warning of tornadoes, to measure and forecast rainfall quantitatively, and to measure winds, turbulence and wind shear. At the same time research meteorologists are using specialised radar techniques to investigate many poorly understood aspects of atmospheric behaviour : to identify the physics of clear air turbulence, the dynamics of fronts, the structure of the atmospheric boundary layer, the three-dimensional airflow and trajectories of hailstones in thunderstorms, and the patterns of precipitation within mid-latitude depressions. Studies such as these are giving fresh impetus to a branch of meteorology, mesoscale meteorology, which largely because of the difficulty of obtaining definitive observations has hitherto been a neglected field. This review highlights the strengths and limitations of radar as a tool for observing the atmosphere and attempts to provide a balanced view of its many applications in meteorology.

It is now 15 years since radars were first used intensively to probe the atmosphere in clear‐air conditions. The first experiments were concerned with the nature of the targets and accounting for the intensity of the measured echoes. It was found that inhomogeneities in the refractive index field were responsible for a large proportion of clear‐air returns. Such returns were detected in characteristic patterns in association with sheared statically stable layers, convective thermals, air mass boundaries, and a variety of wave structures. More sensitive Doppler radars have been developed in recent years which are able to obtain usable signals from all heights in the troposphere. Such radars, as well as providing additional information about the clear‐air patterns observed previously, enable continuous measurements of wind profiles to be made. This paper describes the phenomena which have been observed and the measurements which have been made with radars under clear‐air conditions. A summary is given of the types of targets observed, and the kinds of radars used in clear‐air studies are briefly described.
