Wind is a dominant factor in the climate of Terra Nova Bay, it experiences katabatic winds from the west, barrier winds from the south and eastern flows. The katabatic winds are particularly strong in Terra Nova Bay and originate from the SW if from the Priestly glacier and NW if from the Reeves glacier, forming a polynya event. In summer 30% of the winds are katabatic and 50% in winter and are often paired with Lee wave
In meteorology, lee waves are atmospheric stationary waves. The most common form is mountain waves, which are atmospheric internal gravity waves. These were discovered in 1933 by two German glider pilots, Hans Deutschmann and Wolf Hirth, abov ...

Gerlache Inlet

Evans Cove
.
A cove in Terra Nova Bay, entered between Inexpressible Island and Cape Russell.
First charted by the BrAE, 1907–09.
Probably named by Shackleton for Captain P.P. Evans, master of the ship ''Koonya'', which towed the Nimrod south in 1907, and later master of the Nimrod during the last year of the expedition.
Inexpressible Island
.
An island, long, in Terra Nova Bay, lying close south of the Northern Foothills at the outer edge of the Nansen Ice Sheet.
First explored by the Northern Party of the BrAE, 1910–13, and called "Southern Foothills" in contradistinction to the Northern Foothills.
The name was changed to Inexpressible Island by the party after spending a very unpleasant winter on half rations in a cave in a snowdrift on the island.
Relief Inlet
.
A narrow inlet at the southwest corner of Terra Nova Bay.
The feature is formed along a shear plane caused by differential ice movement near the coast of Victoria Land involving the north edge of Drygalski Ice Tongue and south extremities of the Nansen Ice Sheet.
So named by the South Magnetic Polar Party, led by T.W.E. David, of the BrAE, 1907–09, because, after almost giving up hope of rescue, the Nimrod picked up the party here.
