The purpose of this study is to explore the relationships between the MJO and atmospheric conditions in the months of winter and summer in the Arctic. Here preliminary results will be presented to show the variability of four key atmospheric variables, 10-m surface winds, 500-mb geopotential height, mean sea level pressure, and 2-m air temperature, by phase of the MJO from 1979 to 2011. Atmospheric fields from NCEP/NCAR reanalysis version 2 and MJO phases from the commonly used Real-time Multivariate MJO (RMM) index will be used. Focus will be given to summer months of August, September, and October and winter months of December, January, and February, during which sea ice reaches its minimum and maximum extent respectively. Future work will then use these composite anomalies as the basis for a physical interpretation of observed intraseasonal variability in Arctic sea ice and snow cover.
