Optimized arctic observations for improving weather forecast in the northern sea route

The Northern Sea Route could be an attractive shipping route during Arctic ice-free periods; however, the decline in sea-ice extent could also cause severe weather phenomena, which could disturb ship navigation in turn. The sparse observational network over the Arctic Ocean makes weather and sea-ice forecasts less accurate and increases uncertainties. However, we show that the quality of weather and sea-ice forecasts can be improved by optimizing the Arctic-observing network. —> Read More
