Radar and Surface Measurement of Rainfall during CaPE: 26 July 1991 Case Study
Conventional usage of multiparameter radar measurements for rainfall estimation has been associated with tracking the variability of the raindrop size distribution. The use of multiparameter radar measurements in a statistical framework to estimate rainfall is presented in this paper. The techniques developed in this paper are applied to the radar and rain gauge measurement of rainfall observed...
متن کاملAccurate Rainfall Measurement: The Neglected Achilles Heel of Hydro-Meteorology
Rainfall measurement has an extensive historical precedent. Attempts have been made to standardise measurement procedures. This has never been successfully achieved. There are many sources of measurement error, some of which are compounded by poor rain gauge siting and a variation in gauge height. By far the worst cause of measurement inaccuracy is due to windinduced undercatching. Some solutio...
متن کاملTemporal variation of interrill erosion under different rainfall intensities in semi-arid soils
Interrill erosion can change during rainfall due to change of soil conditions. This research was carried out to investigate the temporal variation of interrill erosion in different soils under different rainfall intensities. For this purpose, laboratory experiments were carried out in three soil textures consists under three simulated rainfalls under slope of 10 percent in three replications...
متن کاملDetermination of the best time series model for forecasting annual rainfall of selected stations of Western Azerbaijan province
Rainfall is one of the most important components of the water cycle and plays a very important role in the measurement of climate characteristic in any area. Limitations such as lack of sufficient information about the amount of rainfall in time and space scale and complexity of the relationship between meteorological elements related to rainfall, causes the calculation of these parameters usin...
متن کاملMeasurement on physical parameters of raindrop energy
Rainfall erosivity factor (R) is one of the most commonly used factors in soil erosion models. While rainfall energy (E) is the most elementary physical parameter to predict R. Based on comparative analysis of previous soil erosion models and rainfall erosivity factor measuring methods, integrated application of modern photogrammetric techniques, image analytic methods and automatic control the...
متن کاملCalibration of a rainfall-runoff model using radar and raingauge data
Since raingauges give pointwise measurements the small scale variability of rainfall fields leads to biases on the estimation for the rainfall over the whole basin. In this context meteorological radars have several advantages since a single site is able to obtain coverage over a wide area with high temporal and spatial resolution. The purpose of this study is to compare the capability of the t...
