Stars and planets.

Bajo la forma de preguntas y respuestas trata de despertar la curiosidad por la astronomía haciendo hincapié en las características e interrelaciones de las estrellas y planetas en nuestra galaxia. Exploran diversos aspectos de la astronomía, incluyendo el sistema solar, estrellas, planetas, lunas, asteroides y cometas. Recomendado para niños de ocho a doce años.

Stars and constellations.

Describe los orígenes y la composición de las estrellas y las constelaciones contestando a preguntas como si hay constelaciones de ochenta y ocho estrellas, si nuestro sol brillará otros cinco billones de años o si las estrellas gigantes se convertirán, cuando mueran, en agujeros negros. Tiene glosario, bibliografía y direcciones de internet.

Deck of stars.

Cincuenta y dos cartas que ponen de manifiesto todo sobre el estudio de las estrellas. Paso a paso enseña cómo elegir estrellas mirando los equipos, identificar las constelaciones, y grabar lo visto usando astrofotografía.

Some of my favourite film stars : una experiencia de aula utilizando Internet.

Se describe la experiencia llevada a cabo con alumnos de primero de ESO en la asignatura de Inglés y que consistía en la búsqueda de un personaje de su interés en la página web: www.biography.com y en analizar su biografía a través de diversas actividades utilizando el idioma inglés. Los objetivos del trabajo son: desarrollar la capacidad lectora de los alumnos en inglés aún cuado no entiendan todo, leer para obtener la información específica, aprender a intuir el significado de palabras desconocidas por el contexto, practicar el vocabulario y las estructuras estudiadas, conseguir que los alumnos adquieran confianza a la hora de enfrentarse a páginas web en inglés y capacitar a los alumnos para que realicen búsquedas en Internet de material en inglés.

When the rising dragon sees fading stars: China's view of the European Union. CEPS Special Report No. 73, 29 November 2012

This CEPS Special Report gives an overview of China’s perceptions of the EU and the protection of Chinese investments in Europe since the outbreak of the European sovereign debt crisis, especially since the more concrete talks in late 2011 on possible financial support from China. Although the top leadership of the communist party of China (CPC) changed in its recent handover, the perceptions described in this paper are likely to remain the same, just as the main tenets of China’s foreign policy are unlikely to change in the near future. The report argues that while the EU’s image has suffered greatly from the sovereign debt crisis and the way it has been handled, there is room to improve China’s view of Europe and for the EU to maintain a relatively strong negotiation position towards China.

A Possible Influence of Equatorial Winds on the September 2002 Southern Hemisphere Sudden Warming Event

The stratospheric sudden warming in the Southern Hemisphere (SH) in September 2002 was unexpected for two reasons. First, planetary wave activity in the Southern Hemisphere is very weak, and midwinter warmings have never been observed, at least not since observations of the upper stratosphere became regularly available. Second, the warming occurred in a west phase of the quasi-biennial oscillation (QBO) in the lower stratosphere. This is unexpected because warmings are usually considered to be more likely in the east phase of the QBO, when a zero wind line is present in the winter subtropics and hence confines planetary wave propagation to higher latitudes closer to the polar vortex. At first, this evidence suggests that the sudden warming must therefore be simply a result of anomalously strong planetary wave forcing from the troposphere. However, recent model studies have suggested that the midwinter polar vortex may also be sensitive to the equatorial winds in the upper stratosphere, the region dominated by the semiannual oscillation. In this paper, the time series of equatorial zonal winds from two different data sources, the 40-yr ECMWF Re-Analysis (ERA) and the Met Office assimilated dataset, are reviewed. Both suggest that the equatorial winds in the upper stratosphere above 10 hPa were anomalously easterly in 2002. Idealized model experiments are described in which the modeled equatorial winds were relaxed toward these observations for various years to examine whether the anomalous easterlies in 2002 could influence the timing of a warming event. It is found that the 2002 equatorial winds speed up the evolution of a warming event in the model. Therefore, this study suggests that the anomalous easterlies in the 1–10-hPa region may have been a contributory factor in the development of the observed SH warming. However, it is concluded that it is unlikely that the anomalous equatorial winds alone can explain the 2002 warming event.
