Development of grassland modelling techniques with weather forecasts
This thesis investigates different aspects of weather, grass growth and statistical modelling. First, the accuracy of weather forecasts is assessed and improved using bias correction methods at twenty-five Irish locations for weather variables that influence grass growth. For the first time, soil …

Using Neural Networks to Provide Local Weather Forecasts
… applied extensively to both regress and classify weather phenomena. While one of the core strengths of neural networks is rendering accurate predictions with noisy datasets, there is currently not a significant amount of research focusing on whether ANNs are capable of producing accurate forecasts …

Advances in statistical post-processing of weather forecasts, probabilistic forecasting, and modelling of extreme events
Accurate weather forecasts are crucial for a variety of applications. These forecasts are usually generated by ensembles of numerical weather prediction (NWP) models, which give a probabilistic estimate of future weather. However, these ensembles might have biases and errors in dispersion, thus …

Optimization of airport terminal-area air traffic operations under uncertain weather conditions
Convective weather is responsible for large delays and widespread disruptions in the U.S. National Airspace System, especially during summer. Although Air Traffic Flow Management algorithms exist to schedule and route traffic in the face of disruptions, they require reliable forecasts of airspace …

Discrete real-time flight plan optimization
… optimizations, while en-route using updated weather forecasts, provides results that are more interesting. If the weather forecasts and the optimizations are done simultaneously every 3-hour or 1.5-hour, the average delay respectively becomes 2.6 minutes or 2.0 minutes. The second part of …

La meteorologia: cammino storico-epistemologico e studio del suo stato attuale di diffusione
… in meteorology is mostly driven by the fact that weather affects our daily life, extending its influence beyond the mere economical impact. Despite this strong attention to meteorology it is seen quite differently from other scientific activities like, for instance, classical physics to which it …

Characteristics of deep moist convection and rainfall in cut-off lows over South Africa
Out of all rain-producing weather systems, cut-off lows (COLs) are linked with the occurrence of high impact rainfall and in some cases short-lived floods which can last for 24 hours over South Africa. This study examined the characteristics associated with the present occurrence of the severe COL …
