|January 20, 1978
Resumen
Los eventos de calentamiento repentino estratosférico (SSW) causan anomalías climáticas significativas en los Estados Unidos. Fuertes eventos de SSW, como en enero de 1977, conducen a severas caídas de temperatura y cambios climáticos persistentes.
Área de la Ciencia:
- Ciencias de la atmósfera Ciencias atmosféricas.
- Climatología y climatología.
- Meteorología Meteorología.
Sus antecedentes:
- El calentamiento repentino estratosférico (SSW) es un fenómeno de ondas a escala planetaria que tiene un impacto en los patrones climáticos globales.
- Enero de 1977 experimentó anomalías climáticas consistentes con un fuerte evento SSW.
Objetivo del estudio:
- Para analizar las anomalías meteorológicas en los Estados Unidos durante enero de 1977.
- Para correlacionar estas anomalías con el fenómeno del calentamiento repentino estratosférico (SSW).
Principales métodos:
- Análisis de datos meteorológicos de enero de 1977.
- Identificación de los parámetros meteorológicos asociados con los eventos de SSW.
Principales resultados:
- Las anomalías meteorológicas de enero de 1977 se alinean con las características típicas de SSW.
- Los fenómenos observados incluyeron cantos de bloqueo, calentamiento polar, enfriamiento en latitudes medias y caída de las temperaturas continentales.
- Estas condiciones persistieron durante al menos un mes.
Conclusiones:
- Las anomalías meteorológicas severas en los EE.UU. durante enero de 1977 fueron un resultado directo de un fuerte evento de calentamiento repentino estratosférico (SSW).
- Los eventos de SSW influyen significativamente en los patrones climáticos regionales y continentales, lo que lleva a condiciones extremas.

01:07What is Weather?
Overview
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.
01:50Global 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.
01:18Variation 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...
01:17Precipitation and Co-precipitation
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
