La Nina trying to wake up?

Temps haved cooled down (Seen by the blue colors) in the Eastern Pacific equatorial region in recent weeks and also in part of the Central Pacific in the El Nino 1-2 and El Nino 3 areas.Is this a sign that la nina pattern soon will wake up or neutral ENSO conditions will prevail during the next 6 months? This will be very interesting to follow in the next few weeks.

Question: Does La Nina mean more Atlantic Hurricanes? IIRC during the last major El Nino there were few hurricanes something about wihd shear in the Atlantic caused by warmer Pacific waters. Please correct me if I'm wrong on this.

When La Nina is in the Pacific it enhances hurricane activity in the Atlantic.

When El nino is in the Pacific it supresses Hurricane Activity in the Atlantic.

But at link below you can see in detail how the whole el nino/la nina patterns work to change the climate patterns in the world not only in hurricane seasons.

If and is still a big if La nina develops fully the effects would be felt in early 2006.

Oh, interesting. What does it affect on North America? More tornadoes, or winter storms or something?

This cool phase was expected weeks ago and I touched base with ..I think Derek Ortt about this upcoming cool phase...warm below in western Pacifc ...move east later..

Will post a ENSO discussion in near future....A strong SOI phase is on the horizon.

Yes it was strongest in 1998' and 1999 but it lingered on into 2000 but it was not as strong...SST wise. 1998 had a strong positive SOI phase go hand and hand with it while both the summer's of 1999 and 2000 had negative SOI trends show up in June.

North Carolina does tend to be on the receiving end of storms during La Nina years but this is just mother natures way of bringing you rains after the dry times/drought.

We got beneficial rains from your storm, Floyd , during 1999 in the Washington DC area. We were in a very bad situation before his precipitation came our way. I know he was not all that plesant from NC's perspective.

Floyds flooding in NC was obviously helped by Dennis stalling for a week 2 weeks before
