Abstract: Sequential analyses of data from a network of eight special rawinsonde stations 100 km apart demonstrate the important effects of mesoscale disturbances in a 2½-hr episode of light-to-moderate clear air turbulence (CAT). ...

Abstract: Seventeen thunderstorm complexes, observed by TIROS satellite over the United States, were investigated. The diameter of the conspicuously bright storm cloud shield, composed of integrated thunderstorm anvils, has been ...

Abstract: More than 1000 hr of radar records taken with the APS-34 1.25-cm vertical-beam radar during a four-year period have been readily classified into four clearly recognizable types. A limited number of precipitation growth ...

Abstract: Sinusoidal variations in the longitudinal speed of the wind in the planetary boundary layer are observed with a C-band multiple-gate Doppler radar using snow as a wind tracer. These undulations in the horizontal wind are ...

Abstract: Analysis of radar film from New England and the midwest has shed additional light on the relation of precipitation-line motion to upper winds, the direction of motion, the line lifetimes and the regious of appearance and ...

Abstract: Twenty-one vortex cloud patterns from TIROS I wide angle photographs were related to the pertinent features of the corresponding synoptic analyses. A five-stage model depicting the evolution of a cyclonic vortex pattern ...

Abstract: A unique method that provides for relating radar-measured reflectivity factors to snowfall rates at the ground is presented. Data were provided by a CPS-9, 3.2 cm radar from six 1978 Massachusetts snowstorms A best-fit ...

Abstract: Doppler wind soundings were taken in the lower 4.5 km of the atmosphere at 12 minute intervals during a seven hour period in a snowstorm over eastern Massachusetts. A time-height cross section of the wind revealed numerous ...

Abstract: The results of simultaneous studies of clear air turbulence (CAT) in the lower 15 km of the atmosphere by multi-wavelength radar, jet aircraft and special rawinsondes at the JAFNA radar facility at Wallops Island, Va., are ...
