It was reported at WG-SAM-2019 that the sea ice concentration (SIC) of RB 48.6-5 corresponded well with the dynamics of monthly sea surface temperature (SST) anomaly in RB 48.6-5. However, in the prediction of SIC in RB 48.6-5 using the monthly SST anomaly, there is a limitation. Because RB 48.6-5 is covered by ice for almost 100% from April to October, consequently there is very little information on the SIC during this period. However, the SST of RB 48.6-2 can be used to predict the SIC in 48.6- 5. There is not a strong correlation of SST between 48.6-2 and 48.6-5.
However there are similar SST positive spikes both in 48.6-2 and 48.6-5 and it is assumed that these are related. This paper analyses the possibilities to predict the SIC in 48.6-5 for the following season using the daily SST of 48.6-2.
