Butlletí del 20/03/2015

El Cheminées Poujoulat ha estat navegant cap a l'est amb vents frescos del nord entre l'alta pressió al seu nord-oest i la baixa pressió sobre el golf de Cadis. Aquest flux es moderará mentre naveguin més a l'est, cap a la baixa. Probablement buscaran una franja estreta de vent del SW al voltant del costat sud de la baixa per pujar cap a l'estret de Gibraltar.
El Neutrogena i el GAES Centros Auditivos, segueixen navegant rumb nord amb alisis del NE moderats. Tenen un parell de dies més d'aquestes condicions abans de navegar en una dorsal i virar cap a l'est.
Els vents estan minvant per al We Are Water i el One Planet, One Ocean & Pharmaton en entrar en les calmes equatorials. Els doldrums s'estan movent cap al sud i els seus vents disminuint, de manera que es preveu una travessia lenta.
Encara navegant davant la costa sud-est del Brasil, el Renault Captur segueix avançant gradualment al nord-est en un patró de vents lleugers i amb mar més plana. Els vents inestables han de millorar en el proper dia o dos al entrar en els vents alisis.
L'Spirit of Hungary segueixen beneficiant-se de vents frescos del N / NW al quadrant nord-est de l'alta pressió al seu sud-oest.

5)    Doldrums generally between 05S and the Equator. Light and variable winds within the doldrums, with scattered showers and a few thunderstorms.
6)    North of the Equator, NNE/NE trade winds hold moderate to near 30N. Winds do veer NE with distance north.

00Z SUNDAY (22-MAR-2015)
1)    High (1022mb) near 43S/62W. Low (972mb) near 47S/37W with a  cold front wrapping from 45S/30W to 36S/34W to 30S/44W. A broad flow of S/SW wind extending from the Falkland Islands north to near 30S behind the front.
