Abstract: Cold-air outbreaks from the polar ice caps or winterly continents over the open ocean lead to organized convection that typically starts as longitudinal roll patterns and changes to cellular patterns in downstream direction. ...

Abstract: Eleven cold-air outbreaks from the Arctic sea ice to the open water of the Fram Strait and the Norwegian Sea have been monitored by aircraft during the field campaigns ARKTIS 1991 and ARKTIS 1993. Budgets of mass, water ...

Abstract: Using vertical wind, temperature and humidity profiles in the C-scale triangle during GATE from 2?5 September 1974, the budgets of mass, latent heat and dry and moist static energy are calculated in the lowest kilometer ...

Abstract: A case study of convective patterns observed within a field of stratocumulus is presented. Measurements were made by two aircraft over the North Sea in August 1984 during the KONTROL experiment. The slightly tilted boundary ...

Abstract: During the Lofotes cyclone experiment (LOFZY 2005), two polar lows developed one behind the other inside a cold-air outbreak from the north in the lee of Spitsbergen on 7 March 2005. Buoys, ship, and aircraft measurements ...

Abstract: Atmospheric roll convection within an Arctic cold-air outbreak was observed over the Greenland Sea during the ARKTIS 1993 experiment on 24 March 1993 by in situ aircraft measurements and synthetic aperture radar (SAR) ...

Abstract: A fair weather boundary layer (BL) with light winds and scattered cumulus to 1100 m is examined in the GATE C-scale triangle using data from tethered balloons, surface measurements from the booms of the ships, structure ...
