Description
Summary:During the winter, the Iberian Peninsula was afected for polar or arctic air irruptions which occasionally caused a sudden fa11 in temperatures. This happened in december 1990, with strong frosts in the Castilla area, due to arctic winds to this area as a consequence of a strong anticyclone situation over British Isles and which were brought by low pressures over the Westem Mediterranean. In this work is used the sinoptic superficial maps, topographics of high levels and cloudiness photographs of meteorological european Meteosat satellite. Durante el invierno, la Península Ibérica se ve afectada por irrupciones de aire polar o ártico que ocasionan descensos acusados de las temperaturas. Así ha sucedido en diciembre de 1990, con fuertes heladas en la meseta de Castilla, debido a la canalización hacia el solar ibérico de vientos árticos, por un potente anticiclón situado sobre las Islas Británicas, y que eran atraídos por bajas presiones sobre el Mediterráneo Occidental. En este trabajo se utiliza la cartografía sinóptica de superficie, topografías isobáricas de niveles altos y fotografías de nubosidad del satélite meteorológico europeo «Meteosat».
