Abstract:
In remote areas with steep topography, such as the Tropical Andes, reliable precipitation<br/>
data with a high temporal resolution are scarce. Therefore, studies focusing on the diurnal properties<br/>
of precipitation are hampered. In this paper, we investigated two years of data from Micro-Rain<br/>
Radars (MRR) in Cuenca, Ecuador, and Huaraz, Peru, from February 2017 to January 2019. This data<br/>
allowed for a detailed study on the temporal precipitation characteristics, such as event occurrences<br/>
and durations at these two locations. Our results showed that the majority of precipitation events<br/>
had durations of less than 3 h. In Huaraz, precipitation has a distinct annual and diurnal cycle where<br/>
precipitation in the rainy season occurred predominantly in the afternoon. These annual and diurnal<br/>
cycles were less pronounced at the site in Cuenca, especially due to increased nocturnal precipitation<br/>
events compared to Huaraz. Furthermore, we used a fuzzy logic classification of fall velocities and<br/>
rainfall intensities to distinguish different precipitation types. This classification showed that nightly<br/>
precipitation at both locations was predominantly stratiform, whereas (thermally induced) convection<br/>
occurred almost exclusively during the daytime hours
