Possibility of predicting sea-ice concentration (SIC) in research block (RB) 48.6-5 (Southern part of Subarea 48.6) using sea surface temperature (SST) in RB 48.6-2 (Northern part of 48.6)
Abstract: 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 ... , consequently there is very little information on the SIC during this period. However, the SST of RB 48.6-2 can ...
