La aparición de vientos del oeste sostenidos en la superficie ecuatorial durante el evento cálido del Pacífico de
Science (New York, N.Y.)
|June 8, 1984
Resumen
Una inusual banda de viento del sur precedió al evento de 1982 El Niño-Oscilación del Sur (ENSO). Este patrón atmosférico parece crucial para desencadenar los principales eventos de El Niño-Oscilación Sur (ENSO).
Área de la Ciencia:
- Ciencias de la atmósfera Ciencias atmosféricas.
- Oceanografía La oceanografía es la oceanografía.
- Ciencias del clima Ciencias del clima Ciencias del clima
Sus antecedentes:
- El evento de 1982 El Niño-Oscilación Sur (ENSO) fue una anomalía climática significativa.
- Comprender los precursores de los eventos ENSO es vital para la predicción del clima.
Objetivo del estudio:
- Investigar el papel de los anómalos vientos superficiales del sur en el inicio del evento ENSO de 1982.
- Para explorar las ocurrencias históricas de patrones de viento similares que preceden a los principales eventos de ENSO.
Principales métodos:
- Análisis de los datos de viento de superficie de junio de 1982.
- Comparación con los registros meteorológicos históricos para los años de ENSO (1957, 1965, 1972).
Principales resultados:
- Una banda distinta de viento de superficie sur se formó al este de Australia en junio de 1982.
- Esta corriente del sur cruzó el ecuador antes del inicio de los vientos occidentales ecuatoriales.
- Estos vientos occidentales iniciaron un calentamiento significativo del océano al este de la línea de fecha.
Conclusiones:
- El chorro anómalo del sur se identifica como un componente atmosférico crítico que desencadena la fase vigorosa del evento ENSO de 1982.
- Los datos históricos sugieren que este patrón precursor puede ser común a los principales eventos de ENSO.

01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
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...
01:16What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
01:26General External Flow Characteristics
The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...
01:18Variation of Atmospheric Pressure
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

01:12Precipitation Processes
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...
