2020 Global ACE: NATL - 179.8 - EPAC - 76.5 - WPAC - 148.5 - NIO - 19.2

Looks like the WPAC may be in the lead after Maysak and Haishen even in a slow year.

2016: 15 named storms, 141 ACE
2020: 15 named storms, 44 ACE


Almost 100 ACE difference. Goes to show how storm intensity and longevity counts. Bring it on September 2020!

Above average ACE is expected by CSU in the NAtl over the next two weeks.

The WPac is trying to get a lead before those long-tracking Atlantic hurricanes finally form, and if the models are right, they’re coming within the next week.

Yes but that was the whole 2016 season. We haven't even hit the peak day yet. Still a lot of time left to get long trackers

The Western Pacific is now the global leader in ACE, PDI, and TIKE.

Yes, I am aware that it has not passed September 10 haha I was just giving PERSPECTIVE on ACE values vs Intensity and Longevity. I knew it wasn't a fair comparison because 2020 has yet to explode and 2016 had 4 majors and Matthew's 50 ACE which more than 2020's ACE to date for 15 storms. Super cool.

Wonder how close the Atlantic will get to below average ACE before the next storms form...

[euro6208]

From 7.7 on August 1, Wpac now up to 64.8.

Pretty big increase and takes the lead globally again.

I'd hate to think what would happen next year.

At least one of the current TD’s needs to become a hurricane in order to keep the Atlantic’s ACE above normal.

Yes this season has been record breaking in breaking 2005’s earliest storm naming records, but that is all.

Is possible that the North Atlantic reach and surpasses 100 ACE units if what the models are showing pans out especially with Paulette being a strong hurricane and future Sally. Now at 50.4 per CSU.

Does anyone have reliable 850-to-200-mb VWS data for the past thirty days? I would like to know why Atlantic ACE has been so subpar vs. overall activity.

[gfsperpendicular]

For what it's worth, Klotzbach's numbers have 2020 still above climo.

Dry Saharan air was a factor in August, and I think there has been a persistent TUTT in the MDR which has resulted in MDR storms struggling to intensify.

[TheStormExpert]

Looks like the Atlantic will take the lead in ACE this week with Paulette and Teddy likely to become majors and rack up ACE.

Sally will also help as it gets stronger.

Dry Saharan air was a factor in August, and I think there has been a persistent TUTT in the MDR which has resulted in MDR storms struggling to intensify.

TUTT and location--Paulette, Rene, and Vicky all came off too far north which, on top of putting them in an area where the shear would normally be higher to start with, the waters are cooler in that part of the ocean (especially Rene and Vicky.) Paulette didn't really start taking off until it was completely out of the MDR, and Teddy is far enough south that it's avoiding the shear and cooler waters.

Vicky and Rene would've had a better shot had they been about 5 or so degrees further south at splashdown--and Paulette would've likely been a hurricane much earlier.

North Atlantic begins to acelerate in the count to 100 units.

North Atlantic begins to acelerate in the count to 100 units.

Yeah these low ACE talks are going to become obsolete within the next few days. The Atlantic will be dealing with it's most substantial ACE increase by far in the coming days. Wouldn't be surprised if we had 100-120 ACE by the end of this week.
