Potential predictability of seasonal mean temperature and precipitation is assessed using a moving blocks bootstrap method. The bootstrap method allows the potential predictability of seasonal means to be assessed even for autocorrelated, highly non‐Gaussian, intermittent data. The results reveal that the largest fraction of predictable variance for both temperature and precipitation occur m…
An analysis is presented of two high‐resolution hurricane simulations of Katrina and Rita (2005) that exhibited secondary eyewall formation (SEF). The results support the notion of vortex Rossby waves (VRWs) having an important role in SEF and suggest that VRW activity is a defining aspect of the moat. SEF occurs at a radius of ∼65 (80) km in Katrina (Rita), close to the hypothesized stagna…
