Abstract:
Mountain regions worldwide present a pronounced spatiotemporal precipitation variability, which added to scarce monitoring<br/>
networks limits our understanding of the generation processes involved. To improve our understanding of clouds and precipitation<br/>
dynamics and cross-scale generation processes in mountain regions, we analyzed spatiotemporal rainfall patterns using satellite<br/>
cloud products (SCP) in the Paute basin (900–4200m a.s.l. and 6481 km2) in the Andes of Ecuador. Precipitation models, using<br/>
SCP and GIS data, reveal the spatial extension of three regimes: a three-modal (TM) regime present across the basin, a bimodal<br/>
(BM) regime, along sheltered valleys, and a unimodal (UM) regime at windward slopes of the eastern cordillera. Subsequently, the<br/>
spatiotemporal analysis using synoptic information shows that the dry season of the BM regime during boreal summer is caused<br/>
by strong subsidence inhibiting convective clouds formation.Meanwhile, in UMregions, low advective shallow cap clouds mainly<br/>
cause precipitation, influenced by water vapor from the Amazon and enhanced easterlies during boreal summer. TM regions are<br/>
transition zones fromUMto BMand zones on the windward slopes of the western cordillera. These results highlight the suitability<br/>
of satellite and GIS data-driven statistical models to study spatiotemporal rainfall seasonality and generation processes in complex<br/>
terrain, as the Andes.
