By the time it reaches the coast, hurricane - force winds, known as katabatic winds, result.

Not exact matches

Katabatic winds, caused by cold air accelerating as it slides off the polar plateau, have battered us for 36 hours.

«Below 60 ° S winds are largely katabatic, this is a result of cold air forming over the pole and falling (as cold air is heavier).

Strong katabatic winds related to the ice sheets (shown tentatively as stippled black arrows), were probably responsible for ice - free polynya - type conditions off the major ice sheets, causing phytoplankton and sea - ice algae productivity recorded in cores PS2138 - 3 and PS2757 - 8 (for the region off the Greenland - Laurentide Ice Sheet no proof from sediment cores are available.

Such an extended ice sheet associated with strong katabatic winds should have caused polynya - like open - water conditions in front of the ice sheet (Fig. 5a), resulting in increased fluxes of phytoplankton, ice algae and terrigenous matter as observed in the PS2757 - 8 record (Fig. 2c and Fig. 6, Scenario 2), i.e., a situation similar to that proposed for the Barents Sea continental margin (Fig. 5a) 57, 58.

Over the coastal escarpment, the regression coefficients of temperature anomalies with the SAM are an indication that the SAM is tied with the surface energy balance and modulation of the thermally direct circulation as described by Parish and Bromwich (2007); the katabatic winds mix sensible heat towards the surface to balance longwave cooling (van den Broeke et al. 2006).

It is not as windy in the Arctic as near the Antarctic coast, in part because the pressure gradients are weaker, and because katabatic winds do not exist over most of the Arctic.

Known as a Katabatic flow, it generates remarkable winds.
