Hi there redamnesia. Considering what I do for a living I may be the best person in position to answer this.
It is in actual fact, impossible for two hurricanse, or circular storms to merge into one another. Hurricanes need a few things to sustain and create
them. One of them being a warm body of water. When a hurricane moves over this warm water, it essentially "burns up" all that warm water, leaving a
cold trail behind it. This occurs if two hurricanes are coming from the one direction
On some occasions hurricanes may form close together and rotate around each other, at a central point, this is known as the Fujiwhara Effect. When two
already formed storms become close to each other, the stronger storm will cancel, or phase out the weaker storm. They will not create a larger more
powerul storm, as the environment needs equal itself out. Although they may interact with one another, the weaker storm will always be the loser.
Hope that explains it
