The previous Geosynchronous Operational Environmental Satellite (GOES) Series (8-15) was capable of producing 1-km resolution visible images every minute, resulting in an immense dataset which can be used to study convective cloud tops as well as transient low-level cloud swirls in the eye. Simple barotropic computer models have shown that vorticity redistribution in the core of a TC can result in the formation of local vorticity maxima, or mesovortices. The models have also suggested that this process is responsible for polygonal eyewalls and in some instances, rapid intensification. Satellite imagery has proven valuable in the validation of the model results.
