Precipitation variability in tropical high mountains is a fundamental yet poorly understood factor influencing local climatic expression and variety of environmental processes, including glacier behavior water resources. type, diurnality, frequency, amount influence hydrological runoff, surface albedo, soil moisture, whereas cloud cover associated with precipitation events reduces solar irradiance at the surface. Considerable uncertainty remains multiscale atmospheric processes patterns...
Abstract This study used the first detailed radar measurements of vertical structure precipitation obtained in central Andes southern Peru and Bolivia to investigate diurnal cycle melting-layer heights tropical Andes. Vertically pointing 24.1-GHz Micro Rain Radars Cusco, (3350 m MSL, August 2014–February 2015), La Paz, (3440 October 2015–February 2017), provided continuous 1-min profiles reflectivity Doppler velocity. The time–height data enabled determination timing, heights, identification...
Abstract The tropical Andes of southern Peru and northern Bolivia have several major mountain summits suitable for ice core paleoclimatic investigations. However, incomplete understanding the controls on isotopic (δD, δ18O) composition precipitation a paucity field observations in this region continue to limit ice-core-based paleoclimate reconstructions. This study examines four years daily δD δ18O from citizen scientist network northeastern margin Altiplano, identify subseasonal...
Abstract In the context of expected future melt reductions in high‐Andes, buffering capacity non‐glacial stores, and especially high‐altitude bofedal wetlands, is increasing importance. Isotope signatures potentially indicative water undergoing evaporation on transit through bofedales have been found tropics, but end‐member uncertainty has so far prevented streamflow separation using this signal. We undertook a stable isotope sampling campaign over 2022 wet‐dry season transition 53.6 km 2 ,...
