In this numerical study, imposing artificial hills in the region of Wathba and Muzayrah in the UAE territory, we investigate the interaction between topographic flows and thermodynamic sea breeze circulations using WRF and CM1 models. Both models solve the fully time-dependent equations of atmospheric dynamics and thermodynamics, and can realistically represent effects related to land-sea contrasts, transient interactions between storms and mountains, and nonlinearity of blocking and microphysics. Idealized 2D and 3D experiments are designed and conducted to understand both mechanical and thermodynamical effects of the imposed mountains on the prevailing sea breeze flow and on orographic precipitation. Analysis is focused on the changes in sea breeze onset, duration, extent and strength, and the potential for orographic precipitation enhancement under various mountain shapes and heights and different background flows and land-sea thermo contracts. We will present results from these simulations, and discuss the impact of the artificial mountains on the coastal circulation and precipitation formation.
