Atlantic Sea Surface Temperatures and Anomalies

[Kingarabian]

Why are the waters in the GOM so cool? O_o?

[LSU2001]

I don't know where you are seeing the "cool" water in the Gulf of Mexico. I was fishing in the gulf last week and I can tell you the water is bath water hot. According to the maps it is hot enough to support a major hurricane right now and will only continue to heat up as we head into the heart of the season.

The anomalies are simply in the negatives at the moment. That does not mean the water is cool.

Sorry man, I just thought that since the map shows blue it means cold/cool. I was just thinking since the waters are supposedly very warm it should be an orange/brownish color.

So do the negative anomalies indicate that cooling will take place or..?

[SouthFloridawx]

I think they meant above or below normal. So blue being below. Though I could be wrong about term anomaly.

Is that normal from a current weather standpoint (ie temps from the last month), or weather from a seasonal standpoint (say, July's over the years)?

It's an anomaly based on a 1982-2010 (20 year) climatology. If you guys have any further questions about it, you could e-mail Levi. I am sure he wouldn't mind you asking.

Here is the latest maps showing the minimum central pressures supported throughout the atlantic, as well as maximum winds supported throughout the atlantic. Notice how basically 95%> of the gulf can support a Cat. 5 hurricane as of now as well as the MDR. So water temps. should not be a problem throughout the remainder of the season.

[RL3AO]

Water temps are never a problem in the Atlantic. Its always dry air and those low level easterlies.

[cycloneye]

Can you imagine the MDR being like this now? Well,is not today but from March 27 when the MDR really warmed a lot. But right now is not so warm but let's see if it warms again in the next few weeks to give fuel to those CV systems. or it stays as it s at this time and have less fuel. Also to note is the tripole is very weak right now compared to March 27.


March 27



July 17

Remember that the above is a temperature anomaly graphic, not a temperature graphic. Temps in the MDR were a good bit warmer than normal for March, but just a little above normal for July. Temps haven't cooled there, they're continuing to warm.

Latest atlantic sst anomalies. Lets see if this continues into August and more importantly if the environment will become more conducive for tropical systems to take advantage of this warmer then normal water.

What's causing the waters east of Nova Scotia to be 5 degrees Celsius above normal? That's quite a bit.

For me I would say an improved Hadley Circulation could account for warmer "or" wetter northern temperate zone. Then there is the problem of the ground truth of satellite derived products. Just by looking I can not tell if the above product has been adjusted to the buoy data.

There has been persistent ridging on that part of Atlantic off the coast Nova Scotia since at least June, light winds and more sunlight reaching the waters equals warmer than average surface waters.

Also is related to the warm +AMO and global increase in ocean heat content caused by global warming.

Request please, can you ping me the address?

I wouldn't go that far with the global warming to explain something that has occurred over such a short time frame...however, I agree with the +AMO reasoning to some degree...would also agree with the previous poster who quoted the lack of cloudiness, light winds (reduces upwelling).

I have lived by the water my entire life, the annual average changes have been sustained for many years. This graph is not exclusive to the Atlantic Basin but shows that the deep ocean is absorbing most of the incoming radiation. Last year I recall, an offshore buoy measured temps around 27c (80.6) in NJ coastal waters, this is almost unheard of and never occurred before the 2000's. It is not certain if the AMO is more influential than climate change in affecting Atlantic ocean temperatures.

Clearly you have not been monitoring that general area, sea surface anomalies have been steadily above 1c for years.

['CaneFreak]

A few years of data is hardly enough to say that warmer than normal ssts in the north Atlantic are due to GW. Sorry but this is just not sound science. There are MANY factors at work here.
