“…While spectral transform models using Eulerian time‐stepping are in principle able to resolve the energy spectrum accurately down to their nominal spectral truncation wavelength (with the caveat that in practice some explicit filtering is needed in order to avoid a pile up of energy at the two‐delta scale), grid‐point models, and in general models using a semi‐implicit semi‐Lagrangian formulation, tend to under‐represent the energy density at the shortest resolvable wavelengths e.g. Skamarock (2011). Defining the effective resolution as the wavelength at which the slope of the energy spectrum starts to deviate noticeably from the observed value (or a reference result obtained with higher model resolution), grid‐point models using a C‐grid discretization and horizontally explicit time‐stepping usually have an effective resolution between 6Δ x and 10Δ x (Skamarock 2011).…”

“…Thus the sensitivity of KE to the time step is linked to the temporal truncation errors but is certainly not entirely explained by that. As suggested by Skamarock (2011), using too large time steps with the SLSI scheme can remove some small-scale variability. This is also in agreement with Cullen (2001) and Héreil and Laprise (1996), suggesting that long time steps can damp some physical modes.…”

“…A consequence of using coarse resolution is the considerable smoothing effect embedded in a mesoscale model, which manifests as reduced wind variation in the corresponding frequency/wavenumber range. () Such reduction directly leads to the underestimation of extreme wind . Further, mesoscale simulations are often run for a period of the order of 10 days or longer after the initial forcing, which is practical and useful for obtaining long‐term mean wind statistics; however, such a long simulation time increases the chance for a storm to drift away from the large‐scale forcing, resulting in inaccurate calculation of storm statistics.…”
