Marina Equatorial Countercurrent Phenomenon
Ocean currents are rivers into the sea , large volumes of water moving in the ocean following cyclic and consistently routes , this is called general circulation of ocean currents .
These currents move in the same direction of the wind, thanks to the energy they get from the winds of the surface, touching the sea.
The winds from the East push the water towards the West, in central doldrums allow the current momentum carry water back East .
The change in mobility in the sides of the equatorial currents is minimal due to the high atmospheric pressure , so that the currents move toward the poles and the tropics beyond westerly winds return to the East.
In the northern hemisphere , the currents collide with continents and turn west , to complement the third circle. These currents are divided into warm and cool .
The warm currents start from Ecuador to the poles ; bathe the eastern coasts of continents ; produce elevated temperatures and rainfall.
The North Equatorial Current north of Ecuador is warm and goes from east to west . From it the Gulf Stream , which receives its name to initially pass through the Gulf of Mexico originates.
South of the North Equatorial Current moves eastward opposite equatorial current North and South Equatorial Countercurrent call .
Each year, generally on the coast of Spain, from the month of March-April is affected by the presence of this natural phenomenon , one that causes the displacement of large masses of ocean water toward the American coast , from Costa Rica in Central America, to the peninsula of Baja California.
The consequences of this shift are: sea level rise , high waves , storm surges on a recurring basis and not continuous as well as reduction of area beaches.
The counterflow phenomenon may be weak, moderate and strong, but it is not possible to predict the intensity or the day that will start as the displacement of water are below the sea surface and manifest themselves until their arrival in the area beaches .
The counter appears unexpectedly , affecting semi-fixed installations made with local materials found in the beach area , so it also affects those engaged in providing travel services and unfortunately tourists and locals to the ignorance of this phenomenon , dare to challenge the waves and storm surges.
Due to the materials that can cause damage and even loss of life, should take general safety , which is why the civil protection units located on beaches where there is a higher risk , disclose the following instructions:
Remove semi palapa type establishments that are close to the sea , further afield and offer greater security to the ravages of storm surges.
Protect , if any , fixed establishments located in beach areas with sandbags , among others.
Remove to a more remote location , furnishings and equipment shelters and playgrounds area beaches that are close to the sea.
Put signs of " rough seas " in area beaches and prohibit swimmers get to the sea during the occurrence of moderate and strong tides and surf respective mainly open water.
Owners of small vessels , should be aware of the potential damage to the same, waves and tides .
The general public should know that the currents are below the sea surface and manifest themselves until their arrival at the beach area , a situation which is not possible to issue an early warning , so it is best to avoid being around .
This increase in sea level lasts until mid- autumn (November) , when the Equatorial Countercurrent moves south again following the apparent movement of the sun, this condition causes gradual sea level down , the beach area is enlarge and reduce storm surges.
