O. Roswintiarti et al., TELECONNECTIONS BETWEEN TROPICAL PACIFIC SEA-SURFACE TEMPERATURE ANOMALIES AND NORTH-CAROLINA PRECIPITATION ANOMALIES DURING EL-NINO EVENTS, Geophysical research letters, 25(22), 1998, pp. 4201-4204
Linear teleconnections of El Nino events and precipitation over a regi
onal coastal land mass were analyzed. Two statistical techniques were
used. First, the Empirical Orthogonal Function extracted major varianc
es of the monthly tropical Pacific sea surface temperature anomalies a
nd coastal North Carolina precipitation anomalies. Second, the Canonic
al Correlation Analysis calculated the linear combinations of the anom
aly data sets that were highly correlated. The results show that El Ni
no-related precipitation anomalies along the North Carolina coast were
positive from November to May and negative between June and October c
onsistent with large-scale studies. Results indicate simple, linear st
atistical techniques can be effectively adopted to determine teleconne
ctions on a local scale.
