Abstract: The term ?dipole? implies a seesaw, inverse variations of an element at the extremities of an oscillationsystem. The Southern Oscillation and North Atlantic Oscillation are examples of such mainly standing oscillations ...

Abstract: Expanding on earlier research, empirically based methods are developed for predicting March-September rainfall in northern Northeast Brazil. From a network of 27 raingage stations in Brazil's Nordeste, new rainfall index ...

Abstract: This study expands recent research into the predictability of Indian monsoon rainfall anomalies. In addition to the April latitude position of the 500 mb ridge over India, and Darwin pressure tendency, the May surface ...

Abstract: A complex of anomalies in the premonsoon large-scale circulation setting heralds the interannual variability of India summer monsoon rainfall. The most prominent precursors of precipitation anomalies are the latitude ...

Abstract: A substantial portion of the interannual variability of rainfall at Jakarta, Java, can be predicted from antecedent pressure anomalies at Darwin, northern Australia; the pressure persistence, the concurrent correlation of ...

Abstract: Heat budget estimates for the global tropics are derived from recent calculations of the oceanic heat budget and satellite measurements of net radiation at the top of the atmosphere. Annual mean heat export from the zone ...

Abstract: Climate-prediction research in the 1980s has shown particular promise for methods based on (a) general circulation and statistics, and (b) numerical modeling. Empirically based methods of predicting seasonal rainfall ...

Abstract: Climatic disasters are common in many tropical regions, and rainfall anomalies in particular have a severe human impact. Accordingly, both the World Climate Programme and the U.S. National Climate Program have identified ...

Abstract: 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, including the Central American?Caribbean ...

Abstract: Departure characteristics of the general circulation in the tropical Atlantic and eastern Pacific are studied in relation to extreme climatic events identified from collectives of long-term rainfall stations and other ...
