Deep Learning Prediction Models for Runway Configuration Selection and Taxi Times Based on Surface Weather
… is based on interrelated factors, including weather variables such as wind and visibility, airport facilities such as instrument approach procedures for runways, noise abatement procedures, arrival and departure demand, and coordination of ATC with neighboring airport facilities. The research …

The Effects of the Non-Climatic Inhomogeneities in Surface Weather Station Records on Long Term Trends in Canadian Fire Weather Index System Codes.
… proliferation of studies analyzing the past fire weather trends using daily surface weather stations data. However, not all studies take account of such data's inherent inconsistencies (inhomogeneities) from non-climatic influences. This study shows their influence on the linear trends in the …

Climatic Influences on Residential Energy Consumption
… Upper air circulation patterns are related to surface weather conditions, in that the movement of surface weather systems is governed (to some degree) by the direction of upper air winds. Thus, the frequency value is a surrogate, representing the occurrence of a surface weather environment, …

An analytic examination of the effect of the stratosphere on surface climate through the method of piecewise potential vorticity inversion
… to examine the effect of the stratosphere on the surface of the earth. The method of piecewise potential vorticity inversion was employed in the diagnosis of the magnitude of and dynamics behind the stratosphere-surface link in both the transient and stationary cases. The potential vorticity …

Snowfall Characterization by Field Observation and Atmospheric Sounding
… to microphysical and dynamical processes in weather systems and is further specified by choice of measurement time, related to the statistics of individual falling ice crystals. A snowflake is definable as a single ice crystal having long range order in the crystal lattice or as a …

Dynamical Influences of Sudden Stratospheric Warmings on Surface Climate
… flow regimes which can result in extreme surface weather. The focus of this thesis is to assess sudden stratospheric warmings and their place in the coupled climate system. Portions of this work are dedicated to algorithm development with the aim of quickly and accurately isolating and …

Adapting to Extreme Heat: Social, Atmospheric, and Infrastructure Impacts of Air Conditioning in Megacities - The Case of New York City
… and intense in most large cities. Built-up surfaces also limit cooling mechanisms, leading to warmer conditions in cities, a phenomenon called the Urban Heat Island (UHI). This presents major challenges to reduce adverse health effects of hot weather, particularly in vulnerable populations …

Changes in frequency of extreme temperature and precipitation events in Alaska
… based on daily data from 26 Alaskan surface weather observing stations from 1950 to 2008. Extreme events were defined as the upper one percentile of events. Data were analyzed seasonally for each of six climate regions. Results indicate an overall increase in frequency of extreme …

DESIGN, THERMAL SIMULATION AND ECONOMIC FEASIBILITY ANALYSIS OF A PLANT FACTORY HOUSED IN A UNDERGROUND MINE DRIFT
… of plant factories as it is not affected by surface weather. This study developed a numerical heat transfer model to simulate heat transfer through the surrounding rock envelope using ANSYS Fluent software and the results are used in the thermal simulation to predict heating, ventilation and …

On the Improvements of Boundary-Layer Representation for High Resolution Weather Forecasting in Costal-Urban Environments
… global conversion from natural to man-made land surfaces will only increase. These land-use changes affect the urban surface energy budget which in turn changes the structure of the planetary boundary layer (PBL) above. With current high-performance computing systems, meteorological and built …

Examining the Influence of Aerosols from Air Pollution on Current and Projected Temperatures in the Urban Area of Chongqing, China
… and simulations of urban climate? The Weather Research and Forecasting (WRF) model is used to evaluate the importance of aerosol effects in urban climate simulations, employing a simplified and computationally efficient approach. Two optimised WRF configurations are utilised to assess …

Urban scale phenomena and boundary layer processes in mountain valleys
… adopted as a representative case study of urban weather and climate phenomena in a mid-sized city lying in a mountain valley, is investigated using different methods and on different spatial scales. First the intensity of the Urban Heat Island (UHI) is analyzed evaluating the differences between …
