Abstract

The Levanter is an easterly wind which frequently blows for several hours through the Strait of Gibraltar in summer. In the presence of a strong capping inversion, a synoptic or local scale pressure gradient forces the air through the gap between the orography on either side of the Strait. This flow cannot be resolved with either a global NWP model or a simplified linear model. Results from two Levanter cases, run using the Met Office Unified Model Version 5.3 at 1 km horizontal resolution over a 300 × 250 km limited area domain covering the Strait of Gibraltar, are presented, together with an unexpected source of verification.
