Temporal precipitation variability in the Tropical Andes by means of vertically pointing-band radar (MRR) observations.

Abstract:

Abstract Precipitation in the Tropical Andes is characterized by a high spatio-temporal variability due to the pronounced topography and the local circulation patterns. Generally, numerous precipitation observations are available in this region but these observations often exhibit uncertainties and are usually not available on a sub-daily temporal resolution. Therefore, a detailed analysis of diurnal precipitation variability is not possible. In this study, we present an evaluation of two high-temporal resolution data sets derived from vertically pointing k-band radars (micro rain radars MMR-2) at two sites in the Tropical Andes. These data were collected in Huaraz (Peru) and Balzay (Ecuador) between February 2017 and January 2018. We analysed the annual and diurnal precipitation characteristics and conducted a precipitation classification (deep convection, shallow convection, stratiform) using the fall velocities and a …
