Yes, I agree with Sara. I think Storm is probably acting out on both accounts: to make sure Cirrus knows who's alfa, and probably a little bit of jealousy too.

My Marius does this a lot with Scooter too. Scooter can be minding his own business laying in the cat bed, and Marius will go right over there and shoo him out; or he might be laying on the couch, or on the windowsill (where there's enough room for them both) but Marius will intercede and push him out. How rude! LOL Aaron gets really mad when he does that, but I just tell him that's how the pecking order is. There's really nothing we can do about it. Be sure to give Storm some extra lovins if he's feeling a bit jealous, and praise him when he's being nice to the others. Silly kitties. I sure hope things improve though!
