| Satellite Images and Movies over Japan and the Western USA from 2006 to 2011 |

The series of satellite photos below are constructed from a combination of visible- and infrared-light images. Yellow tones are those of the visible sensor; blue is added from the infrared image. In this representation, white clouds are high, cold, and bright, yellow are warm, low, and bright, and blue are high, cold, and semi-transparent. Ground tends to be a greenish-blue hue, but the outlines of continents and islands and the texture of the Earth's surface makes separation of cloud and ground obvious. The movie loops show about 8 hours of cloud motion. These are infrared images, allowing the motion of cloud systems to be followed during evening and night when visible-light images are not available. The colours in the images highlight the highest cold clouds - usually those associated with larger weather systems. In 2007, a line of thundershowers developing over New Mexico and moving into Texas is characterized by bright red colours.

Mpeg movie showing the movement and development of cloud systems over the western United States from 2000 UTC May 20 to 04 UTC May 21, 2007. The animation shows the development of a line of thunderstorms over Colorado and New Mexico, moving into Texas. California and Arizona are relatively cloud-free while Nevada dodges high-level cirrus. The central eclipse will cross the California coast after 01: 25 UTC May 21, 2012 (18:25 May 20 PDT). Size 700 K. Click on thumbnail image to view animation. |

Mpeg movie loop of cloud movement and development from 2000 UTC May 20 to 04 UTC May 21, 2008. A cold front is moving onshore in northern California, and a larger upper disturbance with thick and thin cirrus cloud is moving across the mountains. At the end of the loop, thunderstorms begin to form in northern Texas. Size 670 K. Click on thumbnail image to view animation. |
