@MattiHuu_YLE @NinaLith Tästä teoriasta (lämpimämpi Arktis -> heikompi ja mutkikkaampi suihkuvirtaus) on ollut paljon tutkimuksia. Osa puoltaa teoriaa (esim. https://t.co/Cu1C7aFC70), mutta suurempi konsensus taitaa olla hyvin vähäisen vaikutuksen kanna

@hausfath @MichaelEMann @Newsweek The high pressure ridge over northern California produces an easterly flow over the Sierra Nevada and the "Diablo" winds are created. This is also seen as an effect of arctic warming. This a good paper https://t.co/IEQDY
@ArgonneForest If you want to learn more about possible links between sea-ice loss and summer weather in midlatitudes, then you could look up work on so-called 'resonance' by @DimCoumou @KKornhuber @MichaelEMann @rahmstorf et al. This review paper is good

@joerainey4 @cnnbrk Same thing, Joe. The slow warming, and fast warming in the Arctic, observably alters the poleward temp gradient & disrupts global circulation patterns in ways scientists are currently trying to define by debate in the peer-reviewed
@agwatertech @BernieSanders The observed increase of global avg temp increases the likelyhood of flooding & drought. The observed increase of quasi-stationary patterns owing to rapid Arctic warming also produces increased risk of flooding & drought
@Jason16615458 @cathmckenna It's both. The warming, especially rapid Arctic warming, disrupts atmospheric circulation patterns and produces planetary waves with greater meridional characteristics on average. https://t.co/GmgXrH7Ukw

@ThomasPecoraro7 @SenFeinstein It's both. The slow warming causes not only thermodynamic change, but dynamic change of the typical atmospheric patterns themselves. https://t.co/GmgXrH7Ukw
@doilookwasted @sasktrevor @cathmckenna These very anomalous heat extremes at high latitudes are intensifying as global circulation continues to become more disrupted by rapid Arctic warming that produces quasi-stationary characteristics of upper level low
@jckanold @cathmckenna In fact, we're now seeing extreme anomalies in several measured parameters that are 5 to 7 standard deviations beyond the mean. You're not paying attention. https://t.co/GmgXrH7Ukw
