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 ice-covered Beaufort Sea

In this phenomenological study we compare nearly simultaneous visible-wavelength advanced very high resolution radiometer (AVHRR) and synthetic aperture radar (SAR) images of a cold air outbreak that occurred off the ice pack in the Bering Sea. The v

With the use of time series of AVHRR imagery we examine a non-typical case of ice motion and lead pattern formation in the Beaufort Sea during a period of persistent southwesterly to southerly winds during 31 March-14 April 1991. Our goal is to sugge

A surface mean-square-slope parameter analysis is conducted for 14-GHz airborne radar altimeter near-nadir, quasi-specular backscatter data, which in raw form obtained by least-squares fitting of an optical scattering model to the return waveform sho

Motivated by the importance of quantifying the regional surface heat balance over Arctic sea ice in studying climate processes, Lindsay and Rothrock (1994) developed a methodology for computing regional surface sensible heat fluxes using readily avai

Hierarchy implies that the study of sea ice can be divided into analysis of subsets of processes based on scale and their interaction with adjacent scales. We apply these concepts to regional sea ice dynamics. The apparent self-similar property of ic

The NOAA P-3 research aircraft carried out measurements of the mean and turbulence structure of the planetary boundary layer on March 27 and 30, 1989, at 83°N, 10°E in the central Arctic. The ice motion was strongly decoupled from the atmosphere; s

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 flow in the lee of the Olym

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 (λ) changes with distance south of the edge of the ice pack. Radiosondes are utilized to obtain values o

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 orientations along the mean wind
