About this Research Topic
We aim to reach a better understanding about the South American climatic patterns associated with multi-decadal variability, particularly the Pacific Decadal Oscillation (PDO). The increasing availability of observational datasets, reanalysis products, and large ensemble climate model simulations allows us to explore the mechanisms of sea surface temperature variability in the Pacific, Atlantic and Indian oceans and their influences on South American climate. The growing number of statistical techniques, machine learning applications, and increasing model resolution provide us with a wide range of new approaches to help advance in this knowledge.
This Research Topic welcomes studies on the impacts of tropical ocean variability on South America in the past, present and future climates, using observations, reanalysis, models, theories, or new methodologies. We would like to receive studies on, but not limited to:
• Atmospheric teleconnections to South America from tropical and extratropical climate drivers;
• Internal variability versus climatic change signals;
• Climate impacts from the Pacific Decadal Oscillation; and
• Influence from the El Niño-Southern Oscillation diversity on South American circulation and rainfall.
We welcome contributions of Original Research articles and Review articles to this Research Topic.
