Dipole. It’s a word often used among meteorologists and climate scientists. But what does it mean?
In weather terms we can simply think of it as this: one side hot, one side cold. So, as a basic principle, it’s pretty direct. But in a world where extremes between hot and cold are becoming more intense, in North America which has just experienced its most extreme dipole anomaly since record keeping began in 1960, it’s also something that’s important to understand as it relates to ongoing human-caused climate change.
For a recent blockbuster scientific paper by Dr. Simon Wang and associates and published in Geophysical Research Letters has now linked this extreme temperature differential, related polar vortex collapse events, and the California drought with both ongoing physical changes to the Earth System due to human caused climate change and to the first rumblings of a monster El Nino in the Pacific
