Troughs are amplifying way sooner than I ever remember...I've literally seen 15 straight cutters on the gfs since mid dec
1997-98. It happens. We have these stretches...decades at times. 80s sucked. Big chunks of the 90s sucked. We had a pretty amazing stretch for a while before 2016. Nina DOES have alot to do with it. Especially when you get one for years in a row this stuff happens. It likely wont change until we get out of this enso phase or something flukey happens to counter the Nina canonical base. Long term enso phase locks tend to strengthen the base state tendencies to suck ass. Once we get a major shakeup in the equatorial PAC ssts I'm willing to bet things change. Would love to have the time and energy to dig as deeply as PSU likes to, and I know this is somewhat simplistic, but this string of several Nina years in succession isn't common....and neither are the pattern analogs so methinks there is a correlation between the 2. Until Nina wanes, we are fucked imho.
