The KnnCAD Version 4 weather generator algorithm for nonparametric, multisite simulations of temperature and precipitation data is presented. The K‐nearest neighbor weather generator essentially reshuffles the historical data, with replacement. In KnnCAD Version 4, a block resampling scheme is introduced to preserve the temporal correlation structure in temperature data. Perturbation of the reshuffled variable data is also added to enhance the generation of extreme values. The Upper Thames… 

Development of a Parametric Regional Multivariate Statistical Weather Generator for Risk Assessment Studies in Areas with Limited Data Availability

Risk analysis of water resources systems can use statistical weather generators coupled with hydrologic models to examine scenarios of extreme events caused by climate change. These require

Improving Stochastic Modelling of Daily Rainfall Using the ENSO Index: Model Development and Application in Chile

Stochastic weather simulation, or weather generators (WGs), have gained a wide acceptance and been used for a variety of purposes, including climate change studies and the evaluation of climate

Stochastic generators of multi-site daily temperature: comparison of performances in various applications

We present a multi-site stochastic model for the generation of average daily temperature, which includes a flexible parametric distribution and a multivariate autoregressive process. Different

Comparison of three multi-site models in stochastic reconstruction of winter daily rainfall over Iran

Spatiotemporal modeling of daily rainfall may establish the spatial relationships between different stations which is important issue in hydro-climatology and has been addressed by various studies.

Evaluating Stochastic Precipitation Generators for Climate Change Impact Studies of New York City’s Primary Water Supply

AbstractWatersheds located in the Catskill Mountains of southeastern New York State contribute about 90% of the water to the New York City water supply system. Recent studies show that this region is

Coupling annual, monthly and daily weather generators to simulate multisite and multivariate climate variables with low-frequency variability for hydrological modelling

Weather generators are usually used to produce an ensemble of climate time series for vulnerability assessments and impact studies in hydrological and agricultural communities. Multisite and

stoPET v1.0: a stochastic potential evapotranspiration generator for simulation of climate change impacts

Abstract. Potential evapotranspiration (PET) represents the evaporative demand in the atmosphere for the removal of water from the land and is an essential variable for understanding and modelling

A probabilistic risk modelling chain for analysis of regional flood events

A probabilistic flood risk modelling chain is proposed for flood risk analysis with consideration of spatial spreading and temporal clustering of the flood events. The proposed method consists of (1)



Improved K-Nearest Neighbor Weather Generating Model

A major limitation of K -nearest neighbor based weather generators is that they do not produce new values but merely reshuffle the historical data to generate realistic weather sequences. In this

A k‐nearest‐neighbor simulator for daily precipitation and other weather variables

A multivariate, nonparametric time series simulation method is provided to generate random sequences of daily weather variables that “honor” the statistical properties of the historical data of the

A single-site, regression-based downscaling method is extended to multi-site synthesis of daily precipitation at stations in Eastern England and the Scottish Borders. Area-averaged precip- itation

Stochastic simulation of daily precipitation, temperature, and solar radiation

Long samples of weather data are frequently needed to evaluate the long-term effects of proposed hydrologic changes. The evaluations are often undertaken using deterministic mathematical models that

A semiparametric multivariate, multisite weather generator with low‐frequency variability for use in climate risk assessments

A multivariate, multisite daily weather generator is presented for use in decision-centric vulnerability assessments under climate change and can be coupled with impact models in a bottom-up risk assessment to efficiently and exhaustively explore the potential climate changes under which a system is most vulnerable.

A statistical comparison of the stochastic weather generators WGEN and SIMMETEO

Weather generators are frequently used to provide weather data when the length of his- torical weather data is inadequate or when future data are required. The main objective of this study was to
