[1] This study addressed the diurnal cycle of rainfall during the summer monsoon season (May to September) around the Indochina peninsula, with a focus on the diurnal cycle’s relationship to terrain. The investigation used 10 year (1998–2007) Tropical Rainfall Measuring Mission Precipitation Radar (TRMM‐PR) observations. Results revealed that the diurnal variations in rainfall over the Indochin...

There is a need to develop improved accelerated test methods for evaluating the leaching of wood preservatives from treated wood exposed to precipitation. In this study the effects of rate of rainfall and length of intervals between rainfall events on leaching was evaluated by exposing specimens to varying patterns of simulated rainfall under controlled laboratory conditions. Lumber specimens w...

Radar rainfall data are affected by several types of error. Beside the error in the measurement of the rainfall reflectivity and its transformation into rainfall intensity, random errors can be generated by the temporal spacing of the radar scans. The aim of this work is to analize the sensitivity of the estimated rainfall maps to the radar sampling interval, i.e. the time interval between two ...

Climatological features of mesoscale rain activities over the Mediterranean region between 5 W–40 E and 28 N–48 N are examined using the Tropical Rainfall Measuring Mission (TRMM) 3B42 and 2A25 rain products. The 3B42 rainrates at 3-hourly, 0.25×0.25 spatial resolution for the last 10 years (January 1998 to July 2007) are used to form and analyze the 5-day mean and monthly mean climatology of r...

(1) Snow melt period of December to April in combination with precipitation (typical of lowland and hilly parts of the Labe, Vltava and Morava catchments). (2) Longer duration of rainfall lasting 10 to 72 hours (rainfall intensified and prolonged by elevation enhancement). (3) Intensive short duration of summer rainfall exceeding (flood peak occurring within hours of rainfall peak, small areas ...

Extreme rainfall events, specifically in urban areas, have dramatic impacts on society and can lead to loss of life and property.Despite these hazards, little is known about the city-scale variability of heavy rainfall events. In the current study, gridded stage IV radar data from 2002 to 2015 are employed to investigate the clustering and the spatial variability of simultaneous rainfall exceed...

We develop a simple stochastic theory for erosion and sediment transport, based on the Poisson pulse rainfall model, in order to analyze how variability in rainfall and runoff influences drainage basin evolution. Two cases are considered: sediment transport by runoff in rills and channels and particle detachment from bedrock or cohesive soils. Analytical and numerical results show that under so...

The effect of rainfall on the metabolism of birds is poorly understood. We measured the metabolism as rate of oxygen consumption (VO2) of four male and four female American kestrels (Falco sparverius) using open-circuit respirometry. We measured VO2 during the spring at ambient temperatures (Ta) of 5, 10, 15, and 25 degrees C in air without rainfall and with simulated rainfall of 2.5 (low rainf...

Accurate rainfall estimations based on ground-based rainfall observations and satellite-based rainfall measurements are essential for hydrological and environmental modeling in the Qaidam Basin of China. We evaluated the accuracy of daily and monthly scale Tropical Rainfall Measuring Mission (TRMM) rainfall products in the Qaidam Basin. A Geographically Weighted Regression (GWR) was used to est...

In this paper, fractal dimensional analysis is used to investigate the Tamil Nadu rainfall dynamics. Here, the time series data of Tamil Nadu rainfall (annual, south west and northeast) has been analyzed using Detrended fluctuation analysis (DFA). For estimating the 110 years rainfall data, the scaling exponent analysis is used. The result shows a varying degree of persistence over shorter and ...
