Disgrifiad
English: A beautifully-formed low-pressure system swirls off the southwestern coast of Iceland, illustrating the maxim that "nature abhors a vacuum." The vacuum in this case would be a region of low atmospheric pressure. In order to fill this void, air from a nearby high-pressure system moves in, in this case bringing clouds along for the ride. And because this low-pressure system occurred in the Northern Hemisphere, the winds spun in toward the center of the low-pressure system in a counter-clockwise direction; a phenomenon known as the Coriolis force (in the Southern Hemisphere, the Coriolis force would be manifested in a clockwise direction of movement).
The clouds in the image resembled pulled cotton and lace as they spun in a lazy hurricane-like pattern. This huge system swirled over the Denmark Strait in between Greenland and Iceland.
Español: Imagen satelital que muestra una depresión centrada en el estrecho de Dinamarca entre Islandia y Groenlandia. Los vientos, atraídos por la zona de baja presión en el centro, doble bajan el efecto de la fuerza de Coriolis, que dan la apariencia de caracol desde el espacio.
Français : Image satellite montrant une dépression centrée sur le détroit du Danemark, entre l'Islande et le Groenland. Les vents, attirés par la zone de basses pressions au centre, se courbent sous l'effet de la force de coriolis, ce qui donne l'aspect spiralé observé ici.
