Abstract: NOAA-4 satellite photos of roll clouds over the Bering Sea are used to derive quantitative information as to how the interval between the clouds (?) changes with distance south of the edge of the ice pack. Radiosondes are ...

Abstract: The NOAA P-3 aircraft was used to collect data in a genesis region for mesoscale comma clouds over the Gulf of Alaska. Aircraft measurements in the genesis region showed that rainbands with spacings of 65?75 km and ...

Abstract: The existence of synoptically distributed, coherent, linear mesoscale features with wavelengths of 12?18 km in a shallow (zl ≈ 150 m) atmospheric boundary layer is documented. These were observed north of Alaska over the ...

Abstract: Aircraft and satellite data an used to study the structure of longitudinal roll vortices in a nearly neutral (zi/L=-1.2, where zi is the inversion height and L is the Monin-Obukhov length) boundary layer over the ice-covered ...

Abstract: Gap winds can be defined as a flow of air in a sea level channel which accelerates under the influence of a pressure gradient parallel to the axis of the channel. In February 1980 two distinct cases of gap winds were ...

Abstract: The behavior of stratified air flowing around an isolated mountain is dependent on an internal Froude number (F), which indicates the relative importance of upstream velocity and vertical stratification. Three cases of the ...

Abstract: A NOAA P-3 research aircraft collected measurements in a storm off of the U.S. West Coast that featured a low-level jet with wind speeds approaching 50 m s?1. These measurements have been used to document mean and turbulent ...

Abstract: The combination of vertical lidar and in situ meteorological observations from two aircraft provide an unprecedented view of the marine atmospheric boundary layer (MABL) during a cold air outbreak. To a first approximation, ...
