FSU COAPS Atlantic Hurricane Season Forecast

On May 29, 2014, COAPS scientists released their sixth annual Atlantic hurricane season forecast. Hurricane season begins June 1 and runs through Nov. 30.

The 2014 calls for a 70 percent probability of 5 to 9 named storms, including 2 to 6 hurricanes. The mean forecast is for 7 named storms, including 4 hurricanes, and an average accumulated cyclone energy (a measure of the strength and duration of storms accumulated during the season) of 60.

Scientists at COAPS use a numerical climate model developed at Florida State to understand seasonal predictability of hurricane activity. The model is one of only a handful of numerical models in the world being used to study seasonal hurricane activity. The model is one of only a handful of numerical models in the world being used to study seasonal hurricane activity and is different from the statistical methods used by other seasonal hurricane forecasters. FSU is the only university in the United States issuing a seasonal hurricane forecast using a global numerical atmospheric model. The model uses the high performance computers at FSU to make predictions of the atmosphere six months into the future. Based on these atmospheric predictions, tropical activity is objectively determined and forecasts are issued around June 1st.
