Scientists link California droughts and floods to distinctive atmospheric waves

The crippling wintertime droughts that struck California from 2013 to 2015, as well as this year’s unusually wet California winter, appear to be associated with the same phenomenon: a distinctive wave pattern that emerges in the upper atmosphere and circles the globe.

Planetary Wave Resonance may cause Heat Waves to last longer

“The idea is that climate change doesn’t merely increase the overall likelihood of heat waves, say, or the volume of rainfall — it also changes the flow of weather itself. By altering massive planet-scale air patterns like the jet stream (pictured above), which flows in waves from west to east in the Northern Hemisphere, a warming planet causes our weather to become more stuck in place. This means that a given weather pattern, whatever it may be, may persist for longer, thus driving extreme droughts, heat waves, downpours and more.”

Atmospheric rivers more frequent and intense during certain phases of ENSO, study says

A new study by Hye-Mi Kim (Stony Brook University) and other researchers has found that the El Niño-Southern Oscillation, which changes slowly and is usually predictable many months in advance, affects how frequently atmospheric rivers make landfall along the western U.S. coast.
