occurring during the day and downslope and downvalley winds occurring at night. These flows are in the mesoscale (10–100 km) realm of the continuum of thermally driven flows on the earth, which span from convective turbulence in the atmospheric boundary layer (∼10 −1 km) to meridional deep convective (Hadley) cells (10 4 km). The downslope (or katabatic) wind, which is the focus of this paper, are driven by buoyancy forces that arise because of nocturnal radiational cooling of sloping surfaces. The

1. Introduction Katabatic winds are thermally driven downslope flows commonly observed in mountainous regions ( Atkinson 1981 ; Whiteman 1990 ; Zardi and Whiteman 2012 ). These flows occur when radiative cooling of the air adjacent to an inclined surface gives rise to a negative buoyancy along the slope. One of the most prominent slope-flow models was formulated by Prandtl (1942) , who obtained the analytical expressions for wind speed and potential temperature from the local equilibriums in

1. Introduction Katabatic winds are airflows that occur above a cold sloped surface. They are driven by gravity that causes colder and more dense air masses to move downhill. As velocity increases, the Coriolis force declines the flow from the downhill direction. As was done in Vihma et al. (2011) , we define the katabatic wind as a downslope wind initially generated by surface cooling. The katabatic winds occur near a surface in the stably stratified atmospheric boundary layer (ABL) and have

1. Introduction Coastal Adélie Land, East Antarctica, lies to the west of an intense climatological katabatic jet that is centered near Cape Denison in Commonwealth Bay ( Parish and Wendler 1991 ) and immortalized in Douglas Mawson’s 1915 book The Home of the Blizzard . The topographic channeling of the gravity-driven near-surface flow gives this region the most intense sustained surface winds on Earth ( Wendler et al. 1993 ; Parish and Walker 2006 ). Katabatic winds can become particularly

1. Introduction Katabatic winds are slope winds that occur over ice sheets and glaciers, and which arise due to the radiative cooling of the surface, which forms a layer of dense, cold air that flows down the ice slope under its own weight ( Davolio and Buzzi 2002 ). These winds are remarkably unidirectional, and can be very persistent and strong ( Parish and Waight 1987 ; King and Turner 1997 ). Typical depths of the katabatic wind layer are of the order of tens to hundreds of meters and

relatively frequent development of strong nocturnal cold pools in the local, shallow depression at the base of the hill. We investigated the climatology—frequency, strength, and temporal evolution of the CP events—for different seasons. Although seasonal effects exist, CP events are not limited to the winter months. The wind data were used to investigate the near-surface conditions along the slope during CP events. As mentioned earlier, the role of katabatic flow in CP production remains controversial
