Comparing A Simple Stochastic Weather Generator With Two Common Statistical Techniques For Gap-filling Daily Rainfall In Hawaiʻi
… variable, complex terrain in Hawaiʻi. A stochastic weather generator (SWG) attempts to model the randomness and temporal persistence of rainfall and can be used as a gap-filling method. This study compares a simple two-state, first order Markov chain SWG for rainfall occurrence and …

A Systems Approach to Modelling the Effects of Climate Change on Agroforestry: A Case Study in Western Tanzania
… in sub-Saharan Africa as the magnitude of weather events increase in severity. Smallholder farmers in western Tanzania are potentially vulnerable to climate change impact as crops rely on precipitation as the only source of water. It is prudent to evaluate different modes of agricultural …

Modelling impacts of climate variability and change on wheat cropping across New South Wales
… rainfall, and solar radiation at 894 weather stations evenly distributed across the NSW wheat belt. Wheat yields at shire level during 1922-2000 (data in some shires were not available in some years) across the NSW wheat belt were obtained from Fitzsimmons (2001). Statistical methods …

Mitigating risk of weather variability to agriculture through improved field workability predictions
Evolving weather-related risks, driven by climate change, will impose challenges on agricultural production systems at a global scale. However, the spatial heterogeneity of cropping practices, current climate, projected climate changes, and environmental factors (such as soil) will influence these …

Interactive effects of n fertilization rate, cultivars and planting date under climate change on maize (zea mays l.) yield using crop simulation and statistical downscaling of climate models
… operate. Statistical downscaling models such as stochastic weather generator (Long Ashton Research Station Weather Generator [LARS-WG]) and delta-based methods (Agricultural Model Intercomparison and Improvement Project (AgMIP) protocols) have not been applied locally to assess the impact of …
