A Diagnosis of a Long-Lasting Blocking Event over the Southeast Pacific Ocean

A long-lasting blocking event occurred over the southeast Pacific Ocean near the west coast of South America from 29 July through 14 August 1986. This blocking happened in a recently found new region of blocking in the southeast Pacific. During the blocking event the transient eddies were forced to move to the north and south of the blocking. This caused precipitation over South America to increase to the north of the blocking high and diminish over southern South America.
