We describe a generalised downscaling and data generation method that takes the outputs of a General Circulation Model and allows the stochastic generation of daily w...

Maize and wheat are main field crops on arable lands in Croatia. According to the data of the State Bureau for Statistics (Statistical Yearbook 2011) in the five-year period (2006-2010) mean used agricultural land in the category arable land and gardens in Croatia was 867123 ha. Mean harvested areas of maize (298412 ha) and wheat (176794 ha) occupied 55% of used arable land of the country. Majo...

BACKGROUND Changes in weather and season have been linked to stroke occurrence. However, the association has been inconsistent across stroke types. Calgary is a city in the Chinook belt and is subject to high variability in weather conditions. METHODS We obtained hourly weather data over a 5-year period from 1996 to 2000; Chinook events were identified according to the accepted definition. We...

genetically modified (gm) foods hold the key to ending hunger and malnutrition in africa.   due to the increasing number of gmos cultivation and delay in the approval of biosafety law in nigeria, it has become necessary to screen maize products in order to determine the identity of the consumed daily foodstuffs. in this study, dna extraction from raw and processed maize foods sold commercially ...

Daily weather data from 1984 to 2018 for 14 stations representing seven regions of Turkey were used estimate reference evapotranspiration (ETref). We performed sensitivity analyses input variables (air temperature, wind speed, and solar radiation) determine the relative effects measurement errors in on accuracy calculated grass (ETos) alfalfa (Medicago sativa L., ETrs) ET. In addition, changes ...

Data mining is a popular concept of mined necessary data from a large set of data. Data mining using clustering is a powerful way to analyze data and gives prediction. In this paper non structural time series data is used to forecast daily average temperature, humidity and overall weather conditions of Kolkata city. The air pollution data have been taken from West Bengal Pollution Control Board...

Stochastic models of daily precipitation are useful both for characterizing different precipitation climates and for stochastic simulation of these climates in conjunction with agricultural, hydrological, or other response models. A simple stochastic precipitation model is used to downscale— i.e. disaggregate from area-average to individual station—precipitation statistics for 6 groups of 5 U.S...

INTRODUCTION Climate and weather variability can have significant health consequences of increased morbidity and mortality. However, today the impact of climate and weather variability, and consequentially, of climate change on population health in sub-Saharan Africa is not well understood. In this study, we assessed the association of daily temperature and precipitation with daily mortality by...

Precipitation data sets representing four spatial resolutions were used to evaluate the performance of the Soil and Water Assessment Tool (SWAT) on the basis of reproducing measured streamflow, and to show differences in model parameters when different precipitation data sets are used to calibrate the model. The experiment was conducted on the 786 km2 Ft. Cobb Reservoir experimental watershed (...
