Teleconnections Teleconnections means that weather changes at one location might be related to weather changes at other remote locations. People have been fascinated since at least the latter part of the nineteenth century by the prospect of identifying linkages among weather changes in various parts of the globe. The relationship between El Ni�o events and climatic variations in the Equatorial Pacific region is extremely strong and well-documented. The relationship outside this area is harder to prove. Weather anomalies occur all over the globe every year, but some do tend to recur with most or all El Nino events and are referred to as teleconnections. The Pacific weather system covers about 25% of the world's surface area, therefore it shouldn't be surprising that this system can affect weather in all parts of the world. The Effects of El Ni�o around the world, also known as Teleconnections.
Recent studies have confirmed that ther are correlations in many othe areas of the world between changes in rainfall and El Ni�o events. Correlations are strong in the following areas: the central Pacific and the south-east of South America have above-average rainfall during El Ni�o months, as does Equatorial eastern Africa. Rainfall is well below average during El Ni�o over Papua New Guinea, northern, eastern, and central Australia; north-eastern South America; and India and south-eastern Africa. Clearly, the potential payoff to societies of research that identifies robust teleconnections far outweighs the costs associated with searching for them. |
