Abstract In this study, we propose a volume‐to‐point framework for quantitative precipitation estimation (QPE) based on the Quantitative Precipitation Estimation and Segregation Using Multiple Sensor (QPESUMS) Mosaic Radar data set. With volume consisting of time series gridded radar reflectivities over Taiwan area, used machine learning algorithms to establish statistical model QPE in weather ...

Rapid process cascades can lead to destructive debris flows. Identifying and characterizing the processes conditioning debris-flow occurrence will strongly contribute mitigation of hazards. In recent years, rock slope near “Spitze Stei”, in Kandersteg region, Switzerland, has exhibited elevated displacement rates exceeding 10 cm per day, suggesting a growing instability up 20 million m 3 . The ...

Piemonte region, in the north-western Italy, is characterized by complex orography and Mediterranean influence that often causes extreme rainfall event, during the warm season. Although the region is monitored by a dense gauge network (more than one gauge per 100 km 2 ), the ground measurements are often inadequate to properly observe intense and highly variable precipitations. Polarimetric wea...

In studying the hydro-ecological conditions in northwestern Sichuan of southwestern China, an area at the edge of the Qinghai-Tibet Plateau, stream waters were extensively sampled and analyzed for the stable hydrogen and oxygen isotope ratios (  H and  18 O) which are often excellent indicators for a water body genesis and evolvement. The heavy isotopes of hydrogen and oxygen were found to b...

1. Cerebral proteinases were separated on Sephadex G-100 columns into acid and neutral fractions free from cross-contamination. Acid proteinases were more stable and were purified by additional steps with salt and pH5.0 precipitations, column chromatography on DEAE- or CM-cellulose and free-flow electrophoresis. 2. The separation made it possible to study the properties of the partially purifie...
