a relationship between two distant weather events. The weather phenomenon El Niño, for example, has been linked to a wide variety of events, including wildfires in the Australian Outback, flooding in the Peruvian Andes, and above-normal rainfall in the Greater Horn of Africa.
a correlation between contemporaneous meteorological features at widely separated points over the surface of the Earth
A strong statistical relationship between weather in different parts of the globe. For example, there appears to be a teleconnection between the tropics and North America during El Niño.
Ripples of change that occur far away from the source; wildfires in the Australian Outback and flooding in the Peruvian Andes are teleconnections caused by El Niño.
A statistical relationship between weather in different parts of the globe. More specifically, "teleconnection pattern" refers to a recurring and persistent, large scale pattern of pressure and circulation anomalies that spans vast geographical areas (planetary-scale B greater than 10,000 km). Algebraic signs are often assigned to teleconnections. For simplicity, a positive (negative) phase suggests stronger (weaker) westerly flow in regions of normal climatological westerlies across the extratropics.
A linkage between different meteorological features separated by great distances. For example, statistics show that the rainfall in the southern Sahara (Sahel) varies with the phase of the El Niño Southern Oscillation (ENSO) in the Pacific.
1. A linkage between weather changes occurring in widely separated regions of the globe. 2. A significant positive or negative correlation in the fluctuations of a field at widely separated points. Most commonly applied to variability on monthly and longer timescales, the name refers to the fact that such correlations suggest that information is propagating between the distant points through the atmosphere.
