Other unique analysis is shown, such as the relationship of the Madden Julian Oscillation (MJO) and associated tropical OLR patterns to anomalous events. Connections of sudden stratospheric warming episodes to major hemispheric pattern changes during winter, and their effects on wintertime temperatures are also examined.
Results show that there is a lot of variance in the seasonal indicators and the occurrence of anomalous hot or cold episodes on monthly time scales. However, composite and case study analysis reveals that common synoptic precursor patterns, such as OLR, are identified prior to the occurrence of anomalous heat or cold over the east coast consuming region. These studies collectively show that there are distinct connections between midlatitude synoptic weather patterns over North America and seasonal and subseasonal processes.
