In such situation, errors might occur when predicting the weather in Europe upon the cyclone moving eastward or a blocking anticyclone appears in front of it, which blocks the way.
The interactions between a mid-latitude blocking anticyclone and synoptic scale cyclones that occurred during the summer season, Monthly Weather Review 126(2): 502-515.
Previous studies of blocking anticyclone lifecycles have shown that boundary layer friction was one of the primary forcing mechanisms in the decay process.
In order to thoroughly understand global season and inter-annual variations of blocking anticyclone occurrences and characteristics, as well as long-term climate trends, a study of adequate length for both hemispheres must be conducted.
Even fewer studies have examined seasonal and inter-annual variations of blocking anticyclone
occurrences and characteristics, as well as long-term climate trends in the Southern Hemisphere.
