low-level wind disturbances induced by orographic blocking, often called a barrier jet, can also be important in precipitation over mountainous regions. Low-level moisture transport by barrier jets induced by significant mountain ranges has been shown to strongly influence the distribution of precipitation. In a numerical modeling study, Rotunno and Ferretti (2001) showed that the low-level moisture transport by U p induced by the blocking of southerly winds by the Alps can cause intense

boundary layer, are quite distinct from those over lower-elevated regions (e.g., Liou and Zhou 1987 ; Smith and Shi 1992 ; Shi and Smith 1992 ). While the TP receives strong solar radiation at the surface, the other parts of Asia at such a level are already in the cold middle troposphere. Geographically the TP is located in the subtropics with westerly winds to the north and easterlies to the south in summer, but it provides a barrier to the subtropical westerly jet in winter. Perturbations forced

datasets for research into water and energy budgets. Seasonal and diurnal processes (e.g., low-level jet, monsoon circulation) exert important controls on continental and regional moisture fluxes over a range of time scales. The North American low-level jet is a seasonal and intermittent process that is responsible for the majority of moisture flux into the central Mississippi River basin from the Gulf of Mexico. Another low-level jet phenomenon is present in the vicinity of the Andes Mountains in

) found that ENSO explains 36% of the interannual variability in 1-day extreme precipitation frequency in Tijuana, Mexico. A trough in the subtropical jet, a warm California Current off Baja California, Mexico, and low-level moisture advection feed convective activity in the region ( Cavazos and Rivas 2004 ). Extreme precipitation in São Paulo, Brazil, is related to warm ENSO events, which favor a persistent oceanic South Atlantic convergence zone ( Liebmann et al. 2001 ; Carvalho et al. 2002 , 2004
