Radar Investigations of Convective Patterns in the Clear Atmosphere

Observational Study on the Atmospheric Mixed Layer and Transition Layer Structures Using a Mie Lidar

“…The doughnut structure found here is very similar to those found by Hardy and Ottersten (1969) and Konrad (1970) through microwave radar measurements.…”

“…Recently active remote sensing techniques such as solar, radar, lidar and FM-CW radar have been utilized for the researches of the atmospheric boundary layer (Nater and Richner, 1967;Hardy and Ottersten, 1969;Konrad, 1970;Richter et al, 1973;Russell et al, 1974;Noonkester, 1976;Kunkel et al, 1977;Sasano et al, 1980). These techniques can reveal the mixed layer development and the organized structures of plumes, convective cells and internal gravity waves in the form of image displays, which the conventional point-sampling instruments can hardly obtain.…”

Observational Evidence of Cell Flatness as a Function of Convective Depth and Eddy Anisotropy

“…This phenomenon was most appropriate to consider since cell diameters were appreciably smaller than those for MCC. Aspect ratios and convective depths for six cases of clear air echo returns were extracted from the case studies reported on by Hardy and Ottersten (1969) and Konrad (1970). These results as shown in Fig.…”

Lidar Measurement of Boundary Layer Winds and Convective Structure.

“…These models are supported by few observations , sinc e i t h as b een d i ff ic ul t to o b tain a co n t in uous data set of the growing boundary layer (Willis and Deardorff , 1974;K ato and Phillips;1969) Li dar , the optical equivalent of radar , has been used for a more detailed analysis of the inversion rise mechanism. In clear air conditions , the mo st i m p o rt a n t so urce f o r li gh t r e f l ectio ns to the receiver is aerosol .…”
