Liquid Meccano 1

Sunday, June 27th, 2010

Buen dia  !!

Enclosed find this post with an update for 26th june 2010.
Figure 1 confirm that the last current disagreement stint has finished and Cook (ground true) is flying in a strong surface currents field flowing west, like these observed by the Global models.

Fig 1.- Current fields. 26th June 2010 (Geostrophic field, up and Total field, down).

The Figure 2 (SSHa field) confirms that Cook flies on the south border of a N warm eddy, a similar landscape to this observed the last segments (strong currents flowing west) BUT well reported (since 54 W) by the surface fields output of the global model forecasts..

Fig 2.- SSHa fields. 25th June 2010. Red colour represents currents >0.6 knots.

However, there is another (fascinant !) remark in the SSHa field. I have called it “LIQUID MECCANO”. Anticyclons and cyclone gires observed on the SSHa (figure 3), seems to “engage” like gears gyring in the same direction when contact of an immense clock. A cyclonic eddy located SW Cook is the centre of this successive circles of 4 warm anticyclonic, 6 cold cyclonic and 8 warm anticyclonics rings (figure 3).

This meccano was also observed the last year during the RU27 mission. Scarlet founded some “flower-like” structure of cyclonic and anticyclonic eddies that engaged (cold-warm) or separated (warm-warm, cold–cold). The most fanny is the 4 months after (april 2010), the same “flower – like” features standed in the NE Atlantic. This meccano would avoid lost in the gyring momentum of each particular eddy.

But we can deduce a new and useful finding !! That would also mean that future Atlantic crossing gliders could fly CONSERVATIVE ROUTES (in spite of submesoescalar oscillations).
It looks like the first rutes founded by ancient sailors like Antonio de ALAMINOS, pilot of Juan PONCE DE LEON. Not only were the first European of whom we are certain he visited the territory of what is now the United States 1493-1505, but also he had found the Bahama Channel, which gave a shorter route between Cuba and Europe. Alaminos, who had noticed the unusually strong contrary current at Florida's south coast, is now considered the first sailor who reported a “warm highway” to come back Europe..It was called The Gulf Stream some centuries later.

enjoy !
Force, wind, sea and honour to all of you
