| Summary: | This dissertation examines the relationship between polar cyclones and sea ice cover. Through this research, an archive of polar cyclones is created. The archive contains storms for the time period 01 January 1979 through 31 August 2014 for the Weddell Sea, a region east of the Antarctic Peninsula extending to where the Southern Ocean and Indian Ocean meet. The four defined properties of polar cyclones used in this work are: high wind speeds, low pressures, short duration, and small spatial scales. The storm strength is expressed specifically through the maximum wind speed and minimum sea level pressure. The archive additionally includes characteristics of individual storms including the storm date, duration, strength, and size which are analyzed and compared to changes in sea ice cover during each storm. Subsequently, this research quantifies linkages between polar cyclones and sea ice by computing each storm's integrated kinetic energy as a measure of the size, duration, and wind speeds. Specific linkages ... |
