-A **`parcels.Kernel`** object is a little snippet of code, which is applied to the particles in the `ParticleSet`, for every time step during a simulation. Kernels define the computation or numerical integration done by Parcels, and can represent many processes such as advection, ageing, growth, or simply the sampling of a field.

-In Parcels, we can write a kernel function which integrates this equation at each timestep `particles.dt`. To do so, we need the ocean velocity field `fieldset.UV` at the `particles` location, and compute the change in position, `particles.dlon` and `particles.dlat`.
