Global Storm Tracks, Climatology, and Variability using a Decade of Satellite Observations
Our group utilized ForTraCC (Vila et al., 2008), a cloud area-overlap tracking algorithm. This technique was applied to 11 years of the half hourly NCEP/CPC 4km IR dataset (Janowiak et al., 2001). Using the resulting database of storm tracks, we will discuss the (1) global trajectories, (2) size and scale properties, and (3) the climatology and variability of storms. Early results show that certain regions are favorable for storm formation and dissipation. Additionally, we observe the influence of El Nino and La Nina on storm tracks and properties. These results can be used to develop a baseline climatological state, evaluate weather models, and examine extreme events.
