Bulletin météo du 31 mars 2015

Les hautes pressions s'affaiblissent sur l'Espagne et le sud-ouest du bassin méditerranéen, incitant GAES Centros Auditivos à venir négocier des régimes de brise le long de la côte. La brise de mer devrait s'établir de SE cet après-midi. We Are Water et One Planet One Ocean & Pharmaton font route au nord-est dans le sud d'une dorsale anticyclonique. Ils vont devoir choisir entre des vents faibles le long de la dorsale et des vents plus soutenus mais une navigation au près plus au sud.Renault Captur avance toujours dans des vents relativement faibles mais plutôt stables de NE. Ils devraient bénéficier d'une adonnante qui leur permettrait de mettre un peu plus de nord dans leur route, mais ce en sera pas avant un jour ou deux.

Spirit of Hungary avance toujours à bonne vitesse vers le nord dans des alizés de SE. Mais ils devront bientôt affronter un Pot au noir  qui s'est étendu. Les vents devraient mollir dès ce soir.

*** SYNOPSIS ***
00Z TUESDAY (31-MAR-2015)
1)    Moderate E/SE trade winds from 16S to 04S, where the southern doldrums boundary will be present.
2)    The doldrums will be wide ñ especially east of 30W. There, extremely light and variable winds from 04S to about 01N. West of 30W, some E winds will persist within the doldrums.
3)    The North Atlantic trade winds will be backed NNE west of 30W and mainly moderate in strength from 03N to 18N. East of 30W, N/NNE winds much lighter south of 08N. Then NE moderate trades north of 08N to 22N.
4)    High pressure (1035mb) near 40N/18W. Stronger N winds along the Portuguese coast veering NE from Madeira to the Canary Islands.
5)    In the med, a strong NW mistral out of the Gulf of Lyon, but winds well west of the sailing area. Closer to spain, mainly easing W winds through the Gibraltar Strait, extending to Ibiza. A transition zone across the Gulf of Valencia to Palma, then developing NW winds along the Spanish coast south of Barcelona.
00Z WEDNESDAY (01-APR-2015)
1)    The Trade wind zone of the South Atlantic between 16S and 04S along 30W. E/ESE winds at 16S veer to SE at 04S and the southern doldrums boundary. Strongest winds within the doldrums will be between about 14S and 08S.
2)    Doldrums narrow to 04S to 02S, but Níly winds on the north side are light for some distance N. The doldrums will be wider east of 30W and a narrower west of 30W.
3)    East of 30W, Níly winds veer to more typical NE trade winds and increase. West of 30W, NNE trade winds are more persistent from the Equator to 07N.
4)    From 07N, NE trade winds moderate but somewhat unstable north to 27N. Winds more left-shifted to NNE and stronger off the African coast and between the Canary Islands and Cape Verde Islands.
5)    High pressure (1036mb) near 43S/17W, with a ridge extending southwest to 30N/30W. Generally N winds off Portuguese coast veering to NE/E across Madeira and to 30N.
6)    Light and variable conditions Gibraltar Strait and across the Alboran Sea and much of the southwestern Mediterranean Sea. Local overnight drainage winds and daytime coastal sea breezes.
7)    A NW mistral will be blowing across the Gulf of Lyon, but this breeze is not expected to extend to the Balearic Sea or Gulf of Valencia. Here, coastal drainage winds will dominate overnight and morning hours, with afternoon sea breeze developing along much of the coast.

00Z THURSDAY (02-APR-2015)
1)    The doldrums lying between 05S and 02S at 30W. But even north of the doldrums, there will be some anomalously light and left-shifted winds. Very light and headed conditions are likely even north of the doldrums north to 05N and east of 32W. NNE trades will fill better to the northern doldrums boundary/equator west of about 32W.
2)    North of 05N, NE trades, stronger west of 30W. By 14N, the emphasis for stronger trades shifts to east of 30W, all the way north to near 30N.
3)    High pressure (1029mb) near 32N/31W with a ridge extending northeast to another high (1033mb) over the southern Bay of Biscay. Moderate NW flow from off the Iberian coast to Madeira  and the Canary Islands.
4)    A trough of low pressure will be along the Moroccan coast.
5)    High pressure (1028mb) will be near Palma. Between the high and trough, a moderate to fresh Eíly is expected south of Spain to the Gibraltar Strait. West of the Strait, a strong Eíly outflow into the Gulf of Cadiz.
6)    Along the eastern Spanish coast, from Ibiza to Barcelona, diurnal winds prevail with coastal land breezes overnight and morning, transitioning to SE sea breezes in the afternoon.
