[1] A powerful resonance in the O1 and K1 diurnal tides occurs over the Kashevarov Bank in the Okhotsk Sea. Model studies show that this resonance creates tidal mixing and an associated vertical heat flux, both with diurnal and fortnightly components. In midwinter this flux controls the behavior of the resultant polynya; in early winter it affects the polynya formation. For the midwinter case, examination of numerical results and of imagery derived from the Special Sensor Microwave Imager (SSM/I), the advanced very high resolution radiometer (AVHRR), and the RADARSAT ScanSAR shows that the polynya area varies diurnally and fortnightly.
