A new study co-authored by David Bromwich, research professor of Geography at The Ohio State University and senior research scientist at the Byrd Center was published last month in npj Climate and Atmospheric Science titled Arctic Oscillation and Pacific-North American pattern dominated-modulation of fire danger and wildfire occurrence. The study revealed the possibility of forecasting wildfires using hemispheric climate modes. Namely the Arctic Oscillation (AO) and the Pacific-North American (PNA) patterns can account for fires in some locations. The AO induces higher fire risk in northern Eurasia and central North America, whereas the PNA increases the fire danger across southern Asia and western North America. The study demonstrates that the influence of AO and PNA on potential environmental driven-fires can be anticipated, in some locations on almost 90% of days.
