An investigation into Southern Hemisphere cyclone-sea ice links using long records of NCEP analyses and passive microwave data
Entry ID: ASAC_1080

Abstract: The sea ice data are the SMMR/SMMI data for the period 1978-96. These are in the form of daily (or bi-diurnal) concentration amounts on a regular grid. The data on the extratropical cyclones has been obtained using the automatic algorithm of Simmonds and Keay (2000, Journal of Climate, 873-885). This algorithm was applied to the NCEP reanalysis product for the period 1978-96.
