First Summer North Pole Expedition - Cecilie Skogg and Rune Gjeldnes -2011
Forecast - 23 June 2011 - day 24
General situation
The synoptic situation shows a high pressure system over Greenland with a center of 1032hPa near N75/W32 and a depression over the Arctic Ocean with a core value of 1012hPa near the Pole. The former is declining a little during the next 24 hrs whilst moving to the SouthEast. This allows the Arctic depression to move towards Ellsmere but due to a lack of pos vorticity this system fills and flattens out.
As a consequence the wind will slowly decrease and, starting from tomorrow or the day after tomorrow, the risk for fog increases again.
