Slow performance for longitude means

[stephenworsley]

🐛 Bug Report

When regridding onto a cube whose latitude coordinate has bounds [[-90, 90]] and whose longitude coordinate has many points/bounds, initialising a regridder takes longer than is expected. In order to work correctly, this regridding must be done with a resolution keyword, however internal logic currently means that this is effectively always resolution=2. It seems like ESMF doesn't like long thin cells, so it might be worth rethinking this approach.
