The hydroclimate of the Murray-Darling Basin in southeast Australia has been investigated by estimating the Basin’s atmospheric water balance, based on numerical weather prediction (NWP) output. The water balance has been calculated for the period from 2000 to 2004, using archived output from the Australian Bureau of Meteorology’s mesoscale model, the Limited Area Prediction System (LAPS). The ...

Massive crisis open data is not fully utilized to identify humanitarian needs because most of it is not in a structured format, thus hindering machines to interpret it automatically and process it in a short time into useful information for decision makers. To address these problems, the paper presents a method which merges ontologies and logic rules to represent the humanitarian needs and reco...

nowadays, a lot of frost damage is inflicted upon vineyards because of changing weather conditions as well as introducing new of cultivars and genotypes from different geographical regions. on the other hand, the prevalence of a wide variety of grapes in iran, the provides possibility of selection of superior and cold tolerant varieties (or single plants) which is proposed a strong hypothetical...

abstract in general, garmesh wind in rasht province increases the temperature by 9°c and reduces relative humidity by 47%. the direction of prevailing wind during the garmesh wind is southern and its average speed increases by 2 m/s to 5 m/s. the highest frequency of garmesh wind occurs at 09 and 12 utc in december and january. the occurrence of this phenomenon substantially increases the horiz...

Prediction markets are an interesting instrument to draw on the “wisdom of the crowds”, e.g., to forecast sales or project risks. So far, mainly two market mechanisms have been implemented in prediction markets, the continuous double auction and logarithmic market scoring rule. However, the effects of the choice between these two market mechanisms on relevant variables such as prediction market...

Radiative transfer is one of the most important physical processes in the atmosphere and must be treated accurately in numerical weather prediction (NWP) and climate models. In recent decades there have been many efforts aimed at improving the accuracy of radiation measurements and modelling (for example Murcray et al. 1996; Edwards and Slingo 1996; Mlawer et al. 1997; Sun and Rikus 1999; Li an...

Hanstrum et al. (2002) show from proximity soundings that cool-season tornadoes in southern Australia occur in environments characterised by relatively weak, but still positive, buoyancy in the lower troposphere, and strong wind shear from the surface to 1 – 1.5 km. Threshold criteria based on these proximity soundings (hereafter termed ‘proximity thresholds’) showed that a surface to 700 hPa l...
