    @Gawx Here comes the +AAM surge

    Deep -OLR between 170E and 120W indicates El Niño standing wave convection in the central Pacific, convection is way more intense than normal, this also shows upper level divergence in that area, while the +OLR over Indonesia, indicates upper level convergence and suppression/subsidence. This is all consistent with a flip of the Walker circulation and very strong El Niño coupling (ocean-atmosphere); Bjerknes feedback

    Bjerknes feedback in full force. And yea, the EPAC is about to be off to the races with TC’s this month too

    Yea, not a surprise since the EPAC tropical season doesn’t normally get going in full force until July, normal climo. All indications are that this is going to be a huge EPAC TC season

    Here comes the EPAC TC parade…..

    My guess is that the EURO’s July update on Sunday is also off the charts @Stormchaserchuck1 The equatorial subsurface in the EPAC is ridiculous

    The WPAC is already extremely active with TC’s for sure, but it looks like the EPAC is about to explode with TC’s. In addition to the trade wind reversal and MJO activity, this is going to cause relentless WWBs/westerlies in the weeks and months to come…and with another huge DWKW getting ready to load up, there is no more doubt at this point, this El Niño is going historic ^ “As we enter July, models anticipate the Atlantic to remain generally quiet hurricane-wise. El Niño is dominating the current and forecast conditions in the tropical Atlantic, manifesting as high shear in the Caribbean and less thunderstorm activity than normal. By contrast, the eastern Pacific is expected to spring to life, supported by the El Niño background state. Watch the continuous cyclone activity (orange blobs) in this 35-day GEFS forecast, versus the rather docile Atlantic.”

    ^ “The timing of the last downwelling wave in the loop in 1998 makes that event stronger subsurface, but not across much of the surface. The present event will also grow its own oceanic Kelvin wave response over the next few weeks, thereby probably catching up to the subsurface signal.”

But there is a 30C isotherm this year, and the 28 degree isotherm is farther east than in 1997. Strong recent westerlies and westerlies over the next couple of weeks will continue to advance conditions. The different timings between 1997 subseasonal signals and those this year may explain some of the differences.”

    No coincidence that we saw the twin/triplet tropical cyclones back in April with this super El Niño. A whole parade of them are expected to form this month, keeping the WWBs/westerlies going in their wake as far as the eye can see….

    ^ “El Niño continues to mature, with ongoing and persistent westerly wind anomalies across the Central Pacific. It looks like trades will slacken over the East Pacific in the next couple weeks, allowing warmth to continue propagating east. This is a rather east-based event so far, with Niño 1+2 up over 3.5C already! Models continue to show an impressive peak, with even the relative index (RONI) from CFS forecast to peak over 3C.” Up to +2.3C: Massive WWB in progress:
