Rice and Holmberg model estimates the annual statistics of the rainfall rate from the total rainfall accumulation measured over an average year. This model divides rainfall into two components, viz. the Mode 1 type of rain and Mode 2 type of rain. Mode 1 (M1) represents the total convective...
(b-g) Daily rainfall totals (blue bars) and rainfall accumulations (black lines) at six northwest Queensland stations (see Table 1) from 28 January to 10 February. The stations used for (b-g) are the airports at: Normanton, Cloncurry, Julia Creek, Hughenden and Winton, and the Post ...
from the rate at the original time interval and summing the precipitation depth over time for accumulation periods (in this study, hourly), and was then converted into Cartesian grids. Finally, the precipitation rates from individual radars (if multiple radars were included) were integrated by taki...
Moreover, a combination with a landslide susceptibility map improves the spatial accuracy of the model (Segoni et al. 2015b). The warning system has also an additional module that accounts for the effects of snowmelt and snow accumulation (Martelloni et al. 2013). Analysis of time series ...
For heavy precipitation, the ingredients are summarized through a very simple equation for the rainfall accumulation. At any point on the earth: P=¯¯¯RD, where P is the total precipitation, R is the average rainfall rate, and D is the duration of the rainfall. Thus, for large ...
摘要: Warm-cloud rainfall characteristics observed during field work in Puerto Rico in November 1953 as a consultant for the Puerto Rico Water Resources Authority to investigate the possibilities of stimulating rainfall through cloud seeding are reported. A map and list of 52 references of observations...
temperatures and continental surface characteristics are realistic at the starting dates. Daily rainfall accumulations are available on a 1.5° grid and the week 3 + 4 rainfall is computed from days 15 to 28. The skill is computed considering the same dates between the ensemble mean and ...
The RE-ANN calibration method was employed for the M5 model to successfully map a total of 27.43% DDE grid cells, which was smaller than that of RD2T by a small margin. Results of WRF-ANN downscaling for an independent dataset The second testing stage in this study aimed to further ...
We adopted definitions from previous studies13,42to detect occurrences of CAR events over Taiwan. Initially, a day with a daily rainfall accumulation >0.1 mm was identified as a “rainy day”. Next, three criteria were set up to identify CAR days among the identified rainy days as follows...
While rain gages provide an independent source of rainfall intensity data, they are only able to produce estimates of rainfall accumulation at point locations every 5 minutes, and are often far removed from the nearest vehicle path. Moreover, as shown in Table 1, gages are by far the ...
