CaptionsLow Pressure System in View, Eastern North Pacific
From one of the six trapezoidal windows in the International Space Station (ISS) cupola, the astronauts have a field of view covering an area equal to the length of California, and as wide as from the California coast to central Colorado. The cyclonic vortex visible in this image from the cupola occurred within a large area of low pressure over the eastern north Pacific extending along the entire coast of California to Vancouver Island, Canada. A more vigorous low pressure system (see image ISS027-E-6501) was located to the south of this weaker system. This image shows a weak low pressure area which still has the appropriate conditions to maintain cloud development accompanying the counter-clockwise winds.
The cupola is a panoramic control center for the ISS; it is a dome-shaped module with windows designed for observing and guiding robotic operations outside of the Station. Part of one of the ISS solar panel arrays is visible outside the cupola at image upper left. The 360 degree view not only provides viewing for operating the robotic workstation but also for observing the Earth and celestial bodies.
