<p><b>New page</b></p><div>The <b>ballooning instability</b> is a pressure-driven [[Plasma instability|instability]] characterised by wide poloidal spectra, generally at high toroidal mode numbers, <math>n>10</math>. Ballooning modes typically manifest in the outboard edge region of tokamaks operating in [[H-mode|high confinement regimes]], owing to large edge gradients. This outboard localisation is due to the curvature dependence of the more general interchange instability, where the inboard side of the tokamak typically possesses more favourable [[Magnetic curvature|curvature]]. <ref> D.

== Relationship with ELMs ==<br />
Ballooning modes, coupled with the [[Peeling instability|peeling instability]], are a proposed mechanism for driving the ELM cycle, as part of the [[Peeling-Ballooning Model|peeling-ballooning model]] of [[Edge_Localized_Modes|Edge Localised Modes]] (ELMs).<br />
