Interannual variability and annual cycle: mechanisms of circulation and climate in the tropical Atlantic sector

Auteur :
HASTENRATH, S.

Description :
General circulation mechanisms instrumental in both annual cycle and interannual variability of rainfall are studied with reference to key regions of the tropical Americas and Africa. For most of these regions, rainfall anomalies tend to be associated with departures in the large-scale atmospheric and oceanic fields that correspond to the pattern changes in the annual alternation of dry and rainy seasons. The interannual variability of circulation and climate thus appears in large part as enhancement and reduction of the annual cycle. (JPB).
