Since the boreal winters showed largest variability and clearest teleconnection patterns over the extratropical latitudes (e.g., Blackmon et al. 1984a; Kushnir and Wallace 1989), we choose to analyze the wintertime teleconnections only.

According to sampling theory (e.g., Morrison 1983), a z score statistic Z, at any given grid point, can be defined as follows: ...
