Abstract

The time series of 500 mb heights and 1,000‐500 mb thickness at a network of points over the Northern Hemisphere are filtered in a way which extracts those disturbances with periods in the range 15 to 60 days. Such disturbances are shown to have a maximum amplitude in latitudes 60 to 70 degrees north and be strongly influenced geographically. They are closely linked to the phenomenon of blocking.
