Two Low Pressure Systems, Northeastern Pacific

In these astronaut photographs from the ISS cupola, two distinct cyclonic vortices whirl within an area of low pressure that spanned the Pacific coast from southern California to Vancouver Island.

Astronaut photographs ISS027-E-6501 (Image A) and ISS027-E-6500 (Image B) were acquired on March 20, 2011, with a Nikon D3S digital camera using a 16 mm lens, and are provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center. The GOES-11 image was acquired on March 20, 2011, and obtained from the NOAA Geostationary Satellite Server. The astronaut images were taken by the Expedition 27 crew. The images have been cropped and enhanced to improve contrast. Lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by Susan K. Runco and Michael H. Trenchard, NASA-JSC.
