Content
On 25th April 2009, a possible but unusual pattern called von Karman vortex developed to the lee of Pico island. Very common in Madeira or Canary islands, this feature is not so common in the Azores Islands mainly due to their location in Atlantic Ocean. Note that MSG Infra-red 10.8 and visible 0.6 channels on usual 3km sub-satellite pixel resolution can depict the pattern reasonably well in comparison to NOAA 1km resolution.
