What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula
GraphCast , described by Remi Lam and colleagues at Google DeepMind in a 2023 paper published in Science, replaces the equation-integration step with a trained graph neural network operating on an encoder–processor–decoder structure. Weather variables at roughly one million points on a 0.25-degree global grid are first encoded onto a spherical mesh; a processor network then updates each mesh node’s representation by passing messages between it and its neighbours, repeated across the mesh’s structure so that information can propagate across the globe within a single forward pass; a decoder then reads the updated mesh back out to the original grid to produce the forecast. In general form, a…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
