Meteorological uncertainty and rainfall downscaling

We explore the sources of forecast uncertainty in a mixed dynamical-stochastic ensemble prediction chain for small-scale precipitation, suitable for hydrological applications. To this end, we apply the stochastic downscaling method RainFARM to each member of ensemble limitedarea forecasts provided by the COSMO-LEPS system. Aim of the work is to quantitatively compare the relative weights of the...

A Dynamical Model of Orographic Rainfall

A dynamical model for orographic rainfall with particular reference to the Western Ghats is presented. The model assumes a saturated atmosphere with pseudo-adiabatic lapse rate and is based on linearized equations. The rainfall, as computed from the theoretical model, is in good agreement, both in intensity and in distribution, with the observed rainfall on the windward side of the mountain. Th...

The influence of orographic Rossby and gravity waves on rainfall

Orography is known to influence winter precipitation in Asia and the Indo-Pacific Ocean by mechanically forcing winds, but the dynamics involved in the precipitation response are incompletely understood. This study investigates how two types of orographically forced oscillatory motions alter time-mean winds and precipitation. The quasi-geostrophic omega equation is used together with previous i...

Spatial random downscaling of rainfall signals in Andean heterogeneous terrain

Remotely sensed data are often used as proxies for indirect precipitation measures over data-scarce and complex-terrain areas such as the Peruvian Andes. Although this information might be appropriate for some research requirements, the extent at which local sites could be related to such information is very limited because of the resolution of the available satellite data. Downscaling techniqu...
