Dependence of Rainfall Variability on Mean Rainfall, Latitude, and the Southern Oscillation

Journal of Climate, 1990
Abstract The relationship between the relative variability of annual rainfall, the long-term mean annual rainfall, the latitude, and the correlation between annual rainfall and the Southern Oscillation Index is examined, using data from 974 stations. A nonlinear relationship between these variables accounts for 94% of the variance in annual rainfall ...

A stochastic rainfall model with intensity dependent autocorrelations.

2023
The space-time behaviour of precipitation is very complex. The knowledge of the dependence structures in space and time is very important for the assessment of flood risks. There are many different models available for stochastic simulations of precipitation time series.

Spatial estimation of debris flows-triggering rainfall and its dependence on rainfall return period

Geomorphology, 2017
Abstract Forecasting the occurrence of debris flows is fundamental for issuing hazard warnings, and often focuses on rainfall as a triggering agent and on the use of empirical rainfall thresholds based on rain gauge observations. A recognized component of the uncertainty associated with the use of rainfall thresholds is related to the sampling of ...

Adjustment of range-dependent bias in radar rainfall estimates

Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 2000
Abstract Due to the vertical variability 0f reflectivity and radar sampling geometry, radar rainfall estimation is necessarily subject to biases that are range-related. These range-related errors mirror the vertical structure of reflectivity field as it is perceived by the radar at various ranges.

Modeling Spatial Dependence of Rainfall Extremes Across Multiple Durations

Water Resources Research, 2018
AbstractDetermining the probability of a flood event in a catchment given that another flood has occurred in a nearby catchment is useful in the design of infrastructure such as road networks that have multiple river crossings. These conditional flood probabilities can be estimated by calculating conditional probabilities of extreme rainfall and then ...

Probabilistic rainfall thresholds for flood forecasting: evaluating different methodologies for modelling rainfall spatial correlation (or dependence)

Hydrological Processes, 2011
AbstractRainfall threshold (RT) method is one of the evolving flood forecasting approaches. When the cumulative rainfall depth for a given initial soil moisture condition intersects the threshold rainfall curve, the peak discharge is expected to be equal or greater than the threshold discharge for flooding at the target site. Besides the total rainfall

Rainfall Dependence of Hospital Visits of Aeromonas-Positive Diarrhoea

2013
The numbers of patients with cholera and Aeromonas-positive diarrhoea show similar bimodal seasonality in Dhaka, Bangladesh. Considering the association between these two pathogens, our previous finding that the number of cholera cases increased following the period of high rainfall led us to investigate the potential role of rainfall on the ...

Rainfall effect on soil respiration depends on antecedent soil moisture

Science of The Total Environment
Climate change has a discernible influence on rainfall patterns, thus potentially affecting the intricate dynamics of soil respiration (Rs) and soil carbon storage. However, we still lack a profound understanding of the determinants of Rs response to rainfall events. Here, utilizing a comprehensive 10-year dataset (2004-2013), we explored the direction

Precipitable water and CAPE dependence of rainfall intensities in China

Climate Dynamics, 2018
The influence of temperature on precipitation in China is investigated from two aspects of the atmospheric water cycle: available water vapor and atmospheric instability. Daily observations are used to analyze how rainfall intensities and its spatial distribution in mainland China depend on these two aspects. The results show that rainfall intensities,

Modeling Extremal Dependence Using Copulas. Application to Rainfall Data

2013
Copula distributions are a useful tool to describe dependence between two or more random variables. Sklar’s theorem allows to treat separately the dependence structure (the copula) and the marginal distributions. In the bivariate case, where is the bivariate cumulative distribution function, are the marginal cdfs and is the copula linking the marginals.
