Statement: determination of fetch in a sea ice environment
Abstract: This movie loops through sea ice concentration in the Chukchi and Beaufort Sea. Sea ice concentration (SSC) is measured by satellites on a daily basis. SSC has been measured from 1979 onwards, and thus provides us with a relatively long time-series to assess changes in the Arctic climate. The animation loops through the year 2007, which was a relatively warm year with a low sea ice minimum. The presence of sea ice impacts the time that waves and storm surge can affect the coast. Another parameter that affects waves and storm surge is the fetch-the distance that wind blows over open water. Here we show how we calculate each day the distance to the sea ice edge over all relevant directions (the grey lines). Then we pick the direction that the average wind direction measured at the Barrow airfield for that day and determine the fetch length (the red line).
Theory
This movie loops through sea ice concentration in the Chukchi and Beaufort Sea. Sea ice concentration (SSC) is measured by satellites on a daily basis. SSC has been measured from 1979 onwards, and thus provides us with a relatively long time-series to assess changes in the Arctic climate.
The animation loops through the year 2007, which was a relatively warm year with a low sea ice minimum.
The presence of sea ice impacts the time that waves and storm surge can affect the coast. Another parameter that affects waves and storm surge is the fetch-the distance that wind blows over open water. Here we show how we calculate each day the distance to the sea ice edge over all relevant directions (the grey lines). Then we pick the the average wind direction measured at the Barrow airfield for that day, and determine the fetch length in that specific direction (the red line).
