Little swirls

It is also neat to watch the various types of tropical storms that develop either in very favorable conditions, or sheared conditions.  Tropical Storm Colin was highly sheared and the convection that was over the low level center became displaced to the east exposing this low level center. One particular "hot tower" went up just as the low level center attempted to re-align with the mid level center, and as that tower collapsed a little whirl emerged. What I always find to be remarkable is how long it takes to spin up one of these little whirls: 1.5-2 hours. The animation is much more impressive as this little hot tower goes up, dissipates and out spins the little whirl.
