| dc.description.abstract | The climate in south Ecuadorian is characterized by the complex climatic variability
in the region, causing local hydroclimatic events that cannot be adequately prediction.
Certain global signals synthetize exactly the climatic variability in the planet, which
allow to identify important interactions between global and regional climate
(teleconnections). However, the methodologies employed in this document use
distinct thecniques for extraction of temporal features in global and precipitation
signals, which could entail the detection of connection different patterns. In this
sense, it turn important to analyze and contrast those methodologies in order of to
establish their advantages and complementarities. In this studio, are employed two
methodologies with ability to find characteristic information in different temporal
scales (interannual and interdecadal), codify in climatic signals. For this analysis are
used monthly signals of precipitation of two hydrographic basins, the first with Pacific
regimen (coast region) and the second with Amazonic regimen (Andean region), with
the finality to identify distinct process of action global climate. Among the results
obtained is determined that Trans-Niño Index (TNI) is the signal of mayor interannual
influence in the studio area, followed by Caribbean Index signal (CAR). On the other
hand, in interdecadal scale, the results show that CAR and North Atlantic Oscillation
signals (NAO) are the more important in the Andean and coast region respectively.
Both methodologies grant similar results; nevertheless, the evidence of connections
in distinct temporal scales and their differences in spatial analysis reveal
complementarity between them. | |
