ПОВТОРЯЕМОСТЬ ШТОРМОВОГО ВОЛНЕНИЯ В БАРЕНЦЕВОМ МОРЕ В УСЛОВИЯХ СОВРЕМЕННОГО КЛИМАТА

Estimates of the frequency of storm waves in the Barents Sea are given. The results were obtained on the basis of data from the simulation of wind waves during 1979 to 2010 using the WAVEWATCH III wave model on the nonstructural grid. Number of episodes with various heights of waves (from 4 to 10 m) is calculated for every month in the Barents Sea. The assessment of inter-annual variability of the frequency of storm waves is carried out. There is no significant linear trend for the frequency of storm waves in the Barents Sea for 1979–2010 period. Episodes with wave height more than 6 m were more frequent in 1979–1991, less frequent in 1991– 2002 and more frequent again after 2003. Maximum number of such waves is during 1990 to 1993. Interannual variability of storm waves is very high (for different years the number of storm waves episodes can vary by 2 to 3 times). The coefficient of correlation between the index of the Arctic fluctuation and the frequency of waves more than 7 m high is 0,6. The coefficient of correlation of the number of deep cyclones with the frequency of waves more than 7 m high makes 0,67.
