La corriente subterránea ecuatorial desaparece durante el Niño de 1982-1983
Science (New York, N.Y.)
|December 9, 1983
Resumen
La corriente subterránea ecuatorial desapareció en 1982 debido a los vientos impulsados por El Niño, y luego reapareció en 1983. Esto pone de relieve el impacto de los principales eventos climáticos en las corrientes oceánicas.
Área de la Ciencia:
- Oceanografía La oceanografía es la oceanografía.
- Ciencias del clima Ciencias del clima Ciencias del clima Ciencias del clima
- Oceanografía del Pacífico Oceanografía del Pacífico.
Sus antecedentes:
- La corriente subterránea ecuatorial es una característica significativa de la circulación del Océano Pacífico.
- El evento de El Niño de 1982-1983 fue una importante anomalía climática con impactos generalizados.
Objetivo del estudio:
- Para analizar el comportamiento de la corriente subterránea ecuatorial durante el evento de El Niño 1982-1983.
- Para investigar la relación entre los patrones de viento y la dinámica de las corrientes oceánicas.
Principales métodos:
- Análisis de datos oceanográficos del Pacífico.
- Monitoreo de la pendiente de la superficie del mar y la velocidad de la corriente.
Principales resultados:
- La corriente subterránea ecuatorial a 159 grados O se descompuso significativamente en agosto de 1982.
- La corriente subterránea se invirtió parcialmente en septiembre de 1982 y reapareció rápidamente en enero de 1983.
- Los cambios observados se correlacionan con los ajustes de pendiente de la superficie del mar en toda la cuenca a los fuertes vientos del oeste.
Conclusiones:
- La desaparición y reaparición de la corriente subterránea ecuatorial fue directamente influenciada por los vientos occidentales anómalos asociados con el 1982-1983 El Niño.
- Los ajustes de la pendiente de la superficie del mar juegan un papel crucial en la regulación del comportamiento de las corrientes subterráneas ecuatoriales durante eventos climáticos extremos.

01:28Magnetostatic Boundary Conditions
An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...
01:25Eddy Currents
Since eddy currents occur only in conductors, magnets can separate metals from other materials. For example, in a recycling center, trash is dumped in batches down a ramp, beneath which lies a powerful magnet. Conductors in the trash are slowed by eddy currents, while nonmetals in the trash move on, separating from the metals. This works for all metals, not just ferromagnetic ones.
Other major applications of eddy currents appear in metal detectors and the braking systems of trains and roller...

01:19Magnetic Declination
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...
01:16Electrostatic Boundary Conditions
Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.

01:21Isochoric and Isobaric Processes
A thermodynamic process that occurs at constant volume is called an isochoric process. According to the first law of thermodynamics, heat supplied or removed from the system is partially utilized to perform work and change the internal energy of the system. However, in an isochoric process, the volume remains constant. Hence, the work done by the system is zero. Therefore, the exchange of heat changes the internal energy of the system only.

01:18Boundary Layer Characteristics
When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...
