Orographic Precipitation
■ Abstract The influence of surface orography on patterns of precipitation gives rise to some of the most pronounced climate gradients on Earth, and plays a fundamental role in the interaction between the atmosphere and the rest of the Earth System on a wide variety of time scales. The physical mechanisms involved comprise a rich set of interactions encompassing fluid dynamics, thermodynamics, ...

متن کامل7.2a Orographic Enhancement of Precipitation in Midlatitudes: Results from Map and Improve Ii
When midlatitude baroclinic systems move over a mountain range, the precipitation from the system intensifies over and sometimes upwind of the slope of the mountain barrier. The maximum precipitation occurs on the lower windward slopes in almost immediate response to the orographically induced lifting of the air such that the maximum precipitation may occur well below the summit of the range (e...

متن کاملFactors Governing Cellular Convection in Orographic Precipitation
The development of shallow cellular convection in warm orographic clouds is investigated through idealized numerical simulations of moist flow over topography using a cloud-resolving numerical model. Buoyant instability, a necessary element for moist convection, is found to be diagnosed most accurately through analysis of the moist Brunt–Väisälä frequency (Nm) rather than the vertical profile o...
