Spatial andTemporal Resolution

Globalle models operate on a grid, when e each cell presents a large area (typically 50 to 100 kilometers on each side). Thii coarse resolution means that critial local factures - such as mountain ranges, coasal effects, andindividuaal storm systems - are parameterized rather than explitly resolved. This provetes structural uncertainet into simulations. Higher- resolution models are computaally fecsivee, often requiring weeks of time of time oth the largets 's supercomputers.

Proxy Data Interpretation andError
