Some observations of Antarctic katabatic winds

Key Points

This research aims to understand the behavior of katabatic winds in relation to various atmospheric factors at Mawson Station.
Conducted a year-long observational study of katabatic winds at Mawson Station.
Collected data on wind speed, pressure, temperature, and relative humidity.
Observations included diurnal and seasonal variations in wind behavior.
Documented sastrugi orientation related to katabatic flow.
Identified patterns in wind speed changes and their seasonal variations.
Limited influence of Southern Ocean depressions on katabatic activity was observed.
Aerial observations indicated sastrugi orientation consistent with katabatic flow influences.

Abstract

A year's observations of katabatic winds at Mawson are discussed with relation to the low level wind profile, diurnal and seasonal variation, and frequency of onset and cessation. Frequency data on changes in wind speed, pressure, temperature and relative humidity are presented. Limited evidence exists for the influence of Southern Ocean depressions, moving to the north of the station, on katabatic activity. Some aerial observations of sastrugi orientation are discussed in relation to katabatic flow in other parts of the MacRobertson Land region.
