Not the same and I'm not being difficult. People believe Storm can manipulate matter and energy when it is not organized as weatherpatterns (sometimes a few other elemental patterns like a star), but she can't. She can't shut people's brains down by playing with their electrical activity and she can control the water in people's bodies or make it freeze like Iceman can.
What she CAN do is manipulate the temperature in ANY environment, meaning she can manipulate the temperature around water; even if it's located inside the body. Sure, its not direct molecular manipulation. Whatever. I don't care.
she cant directly control temperature of living beings. she can cool the air arround them and that's the point. She is limited in scope to a particular range of natural phenomenons
