La Niña is expected to continue through the Northern Hemisphere spring 2008.

I thought we had La nina last summer. Here in RI it was one of the worst summers I remember. Sprinkled only twice, and every damned day was 85 and sunny. Disgusting.

If I wanted to live in hell I’d move to California.

Matches up well with yours. Percent of normal precipitation year to date. Red is 10% of normal.

If La Nina’s historically occur at a certain point in the solar cycle, (typically begin around the low level of activity and continue during the rising solar activity), the current La Nina would mean that we are in the time frame normally considered the increasing solar activity period. If this is true, we are going to have a very weak Solar Cycle 24. Might be lucky to peak at 50 sunspots.

According to the charts above, La Nina began in March to April and really got going in the Fall to Winter of last year. Due to your location, the Atlantic probably has the greater influence on your temperatures. Apparently, what you want is that the Gulf Stream stops. That would give you some colder summer days.

La Nina is a convenient “weather god” used by the climate hoaxers to account for their missing warming. It was created for the same reason that all false gods are created, to account for that which they don’t have an answer for or to conveniently account for something that is inconvenient.

Good points. I think the Oscillations basically are the following. After Solar activity has been strong for 4 to 5 years, the Earths Oceans absorb all that extra energy. This then manifests itself as the El Nino (Warming Equatorial Pacific). The El Nino typically shows up as the Solar activity level is dropping due to ocean current lags (the Pacific is immense). After solar activity has been weak for a few years, the heat will have radiated out of the Ocean. The cool Equatorial Pacific then manifests itself as a La Nina. These typically occur during the rising solar activity part of the cycle. My guess would be it takes longer to heat the Equatorial Pacific Ocean, while it is able to radiate the heat quicker. Actually, the El Nino could be considered the radiating phase, not the warming phase. By the time El Nino radiates, the heat radiated will have been absorbed a few years prior. So basically, the La Nina phase needs increasing solar activity to start the warming cycle. So it should not stop until the sun increases its activity.

I really love thunderstorms and what everyone else calls harsh weather. Hurricanes, tornados, waterspouts, blizzards, howling winds and driving rain.

Reminds me of youth.

Sunshine is boring.

Just for fun I went and did a google news archive search for "el nino" and found this story from Time Magazine in 1925:

http://www.time.com/time/magazine/article/0,9171,720226,00.html

It's about a town in Ecuador called Santa Elena that is usually very dry and the story is about how El Nino came in and caused rains and flooding which wiped out the area.

So I did a google news ( current news ) search for that town and found an article posted three days ago about the heavy rains, floods and emergency situation that is happening down there at this very moment.

It seems that they need to keep insisting that la nina, not el nino, is happening right now to account for the cold temperatures which are undercutting their global warming hysteria, since back in 1925 they would be calling this a severe El Nino event on the "dry coast" of Ecuador.

La Nina does seem to breaking up a little

[justa-hairyape]

You are referring to the anomaly in the far Eastern pacific along the western coastlines of Central and South America ? How is the Anomaly calculated ? Is it calculating the real time trend of temperature change or is it calculating the degree of change based on past historic norms ?

It seems that they need to keep insisting that la nina, not el nino, is happening right now to account for the cold temperatures which are undercutting their global warming hysteria, since back in 1925 they would be calling this a severe El Nino event on the "dry coast" of Ecuador.

And its not just the fact that they are blaming their errors on an anomaly. What makes it worse is they do not even seem to care what may be causing the anomaly. IE - They know they are wrong and do not care about correcting their mistake. Easier to blame something or someone else. I believe this is diagnosed as projectionism. They are projecting their faults on the poor little El Nino and La Nina.

A link to an interesting paper was posted on another FreeRepublic thread today. The Sun Also Sets

Here is the paper link. Solar Activity Controls El Niño and La Niña

That author finds significant correlation with El Nino/La Nina periods and solar activity. This correlation is even more significant in the falling and rising area of the Solar Activity curve. IE - The correlation is not strongest with respect to the peak and the bottom parts of the curve. The paper is rather complex and I have just glanced through it at this point in time.

Also, anyone have any ideas what will happen with an extended La Niña after our historic 2007/2008 winter ?

Pardon my ignorance, but what is historic about this winter? It's seemed pretty uneventful in NC.

[justa-hairyape]

Up until the Historic Tornadic outbreak we just had, the southeast was fairly mild. Mainly due to the mild Atlantic. There was one time this winter when the La Nina/Arctic cold managed to penetrate the southeast. What is historic about this winter is the affects of La Nina. There are some lists documenting what has happened, but off the top of my head, here are the following Historic occurrences which seem to be related to the La Nina.

- Recent China Blizzard. Longest lasting in 100 years.
- Snow in Baghdad. First time ever for some old timers.
- Northwest US Blizzards. Numerous single day snow records being set and we are now seeing all time seasonal records being broken.
- Snow occurred in Argentina during their summer.

Those are the main ones I can remember. I am thinking about putting together a list with links, but others will probably get lists together before I get the time (very busy). There are a couple of interesting lists right now. Links below.

Events outside US

This Wikipedia page documents all major storm events this winter. Some of these may have been historic.

These figures demonstrate the progression of this current La Nina.

There is a good animation of the development of La Nina at this link. You can see a 2 month, 4 month or 6 month animation.

Had a chance to analyze the ONI (Oceanic Nino Index) anomaly data at the Climate Prediction Center in a little more detail. At least the past two cycles. There is definitely a correlation between El Nino Oscillations (warming) occurring during the falling solar activity curve and a correlation between La Nina Oscillations (cooling) occurring during the rising solar activity curve. This is a generalization that typically holds true. El Ninos begin at peak or right after the peak of activity and continue until the activity falls to minimum. La Ninas begin at minimum activity or right after and continue up until peak activity is reached. During the rising activity phases, El Ninos come and go. During the falling acitivty phases, La Ninas come and go. There are however exceptions to these general underlying principals. The 1997/1998 El Nino occurred at a time when it should not have. It was also sandwiched between La Ninas. The magnitude of that El Nino was very high and higher then we normally see for what we believe are solar induced Tropical Pacific Oscillations. My guess at this point is that the 1997/1998 El Nino was caused by underwater volcanic activity. The first underwater volcanic eruption was discovered and began in August 1996. The undersea Hawaiian Volcano Loiki erupted on the Hawaiian Pacific hotspot. Then in January of 1997 a warm anomaly occurred at depth in the Pacific and then rose to the surface in April of 1997. Very interesting coincidence. The Pacific hotspot might at times warm the deeper Pacific Ocean waters and could cause El Ninos to appear during rising solar activity phases (normal La Nina period). It is also possible that smaller volcanic activity could be affecting the Pacific anomaly data. We wont know with certainty until these underwater eruptions are monitored more precisely. Other researchers have proposed links between underwater volcanic activity and Ocean temps in the past.

[justa-hairyape]

Anyone want to bet that the warming anomaly occurring in the polar north which appears in the monthly anomaly images above from June to November 2007, was due to underwater volcanic activity ?
