Manche - English Channel

Manche - English Channel

Characteristics

Description

The English Channel (French: La Manche, "the sleeve") is an arm of the Atlantic Ocean that separates the island of Great Britain from northern France.
A number of major islands are situated in the Channel, as the Isle of Wight off the English coast and the British crown dependencies the Channel Islands off the coast of France. The coastline, particularly on the French shore, is deeply indented; the Cotentin Peninsula in France juts out into the Channel, and the Isle of Wight creates a small parallel channel known as the Solent.

 Currents

As the English Channel is entered, and the fairway narrows, the rotatory currents of the approach become gradually more and more rectilinear. The rates of the currents in the fairway vary with the width, and are greatest in the narrowest parts.
In the middle of the fairway, between Bill of Portland and Saint Catherine’s Point, on the English coast, and Cap de la Hague and Pointe de Barfleur, on the French coast, currents attain rates up to about 3.5 knots at springs. In the widest parts, currents seldom attain rates  exceeding 2.5 knots at springs.


Although the surface current has a dominant NE and E directional set, it is influenced significantly by the wind, which is variable in direction during all seasons, although W winds predominate.
The prevailing direction of the North Atlantic current is therefore likely to be most in evidence after strong and long continued SW or W winds.


The time of HW changes rapidly along the French coast, and is about 6 hours later at Le Havre than at lle d’Ouessant. The time at which the tide turns usually differs considerably from the time of local HW. The flows, therefore, cannot be described as “flood” and “ebb”, and are usually termed E and W. However, it must be understood that the E current is that which runs up the Channel, from the Atlantic towards Dover Strait, and the W current that which runs down the Channel, from Dover
Strait towards the Atlantic.

The actual directions of the currents are reported to differ considerably from E or W. In the estuaries and rivers, currents are usually called the “incoming” and “outgoing” but may be referred to as flood and ebb. Among the Channel Islands, the times and directions of the flow differ greatly from those in the fairway of the English Channel. Therefore, care is required when approaching the above localities. The tidal flows at locations to the W and NW of Ile d’Ouessant are significantly affected by current due to the prevailing wind.

La Manche  est une branche de l'océan Atlantique qui sépare la Grande-Bretagne du nord de la France. De grandes îles sont situées dans la Manche comme l'île de Wight au large de la côte anglaise  les Îles anglo-normandes au large des côtes de la France.  Le littoral, en particulier sur la rive française, est profondément échancrée comme la péninsule du Cotentin en France qui s'avance dans la Manche . Au nord de l'île de Wight se trouve le canal de Solent. 


Courants et Marées

En entrant dans  la Manche par l'ouest le chenal se rétrécit, les courants rotatifs deviennent progressivement de plus en plus rectiligne. Les taux des courants dans le chenal varient en fonction de la largeur, et sont les plus importants dans les parties les plus étroites.
Dans le milieu de la Manche, entre Portland et la Pointe Ste-Catherine, sur la côte anglaise, et le Cap de la Hague et la pointe de Barfleur, sur la côte française, les courants peuvent atteindre 3,5 noeuds. Dans les parties les plus larges, les courants atteignent rarement des taux supérieurs à 2,5 noeuds.
Bien que le courant de surface a une dominante NE et E ensemble directionnelle, il est fortement influencé par le vent, qui est variable dans le sens durant toutes les saisons, bien que les vents W prédominent.

Les heures de marée changents rapidement le long de la côte française, et est d'environ 6 heures plus tard au Havre qu'à l'île d'Ouessant. Le moment où la marée s'inverse diffère considérablement localement. Les flux, par conséquent, ne peut pas être décrit comme «montant» et «reflux», et sont généralement appelés E et W. Cependant, il faut comprendre que le courant E est celle qui va jusqu'à la Manche, de l'Atlantique vers Douvres , et le courant W ce qui coule  de Douvres  vers l'Atlantique.

Les directions réelles des courants différent considérablement de l'Est ou l'Ouest. Dans les estuaires et les rivières, les courants sont généralement appelé le «entrant» et «sortants», mais peut être appelé contre les montants et le reflux. Parmi les îles Anglo-Normandes, les heures et les directions de l'écoulement diffèrent grandement de ceux dans le chenal de la Manche. Par conséquent, une grande attention est requise lorsque vous approchez les localités ci-dessus. Les courants de marée dans des endroits à l'W et NW de l'île d'Ouessant sont sensiblement affectés par le courant dû au vent dominant.
