Southern Annular Mode, Foehn Wind, and Larsen C Ice Shelf
The Antarctica Peninsula (AP) has undergone a rapid increase of temperature within the recent decade. One of the leading factors that causes the warming is known as Southern Annular Mode (SAM). SAM is described as the north to south movement of a westerly wind belt that circles the Antarctica. Force...
