Anillo de coalescencia de la Corriente del Golfo con la Corriente del Golfo frente al Cabo Hatteras
Science (New York, N.Y.)
|December 1, 1978
Resumen
Un anillo ciclónico se unió de nuevo a la Corriente del Golfo, formando un distintivo meandro en forma de S en tres días. Este estudio documenta el proceso de reunificación utilizando herramientas avanzadas de medición oceanográfica.
Área de la Ciencia:
- Oceanografía La oceanografía es la oceanografía.
- La dinámica de fluidos es la dinámica de fluidos.
- La oceanografía física es la oceanografía física.
Sus antecedentes:
- Los anillos ciclónicos oceánicos son remolinos independientes que pueden separarse de las corrientes principales como la Corriente del Golfo.
- La interacción y re-entrañación de estos anillos de vuelta a sus corrientes de origen no se entienden completamente.
Objetivo del estudio:
- Documentar y analizar el proceso de un anillo ciclónico que vuelve a unirse a la Corriente del Golfo.
- Para describir la dinámica de flujo geostrófico resultante y los cambios estructurales.
Principales métodos:
- Utilizó sondas de temperatura desechables a bordo para mediciones verticales de la columna de agua.
- Empleó cuatro sonadores de eco invertidos amarrados en el fondo para capturar datos acústicos y rastrear el proceso de reunificación.
Principales resultados:
- Observó la colisión entre un anillo ciclónico de 7 meses de antigüedad y la Corriente del Golfo.
- Documentó la rápida formación de un agudo meandro en forma de S dentro de los tres días posteriores a la colisión.
- Se obtuvieron descripciones sinópticas del evento de fusión, detallando la transformación estructural.
Conclusiones:
- Los anillos ciclónicos pueden reintegrarse con sus corrientes de origen, alterando significativamente la trayectoria de la corriente.
- El proceso de reencuentro es rápido y conduce a la formación de complejos meandros.
- Este evento proporciona datos valiosos sobre las dinámicas de interacción de las corrientes de remolino en oceanografía.

01:03Anchoring Junctions
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...
01:06Divergence and Stokes' Theorems
The divergence and Stokes' theorems are a variation of Green's theorem in a higher dimension. They are also a generalization of the fundamental theorem of calculus. The divergence theorem and Stokes' theorem are in a way similar to each other; The divergence theorem relates to the dot product of a vector, while Stokes' theorem relates to the curl of a vector. Many applications in physics and engineering make use of the divergence and Stokes' theorems, enabling us to write numerous physical laws...

01:59Lagging Strand Synthesis
During replication, the complementary strands in double-stranded DNA are synthesized at different rates. Replication first begins on the leading strand. Replication starts later, occurs more slowly, and proceeds discontinuously on the lagging strand.
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...

01:17Region of Convergence
The z-transform is a powerful mathematical tool used in the analysis of discrete-time signals and systems. It is a crucial tool in the analysis of discrete-time systems, but its convergence is limited to specific values of the complex variable z. This range of values, known as the Region of Convergence (ROC), is fundamental in determining the behavior and stability of a system or signal. The ROC defines the region in the complex plane where the z-transform converges, which can take various...
