As part of the Lake-Induced Convection Experiments (Lake-ICE) (Kristovich et al., 2000), on December 21, 1997 the University of Wisconsin Volume Imaging Lidar (UW-VIL) observed a persistent, shallow lake breeze circulation over western Lake Michigan. In this study, an attempt is made to simulate this small-scale flow using the University of Wisconsin Non-Hydrostatic Modeling System (UW-NMS) (Tr...

Coastal atmospheric conditions widely vary from those over inland due to the land-sea interface, temperature contrast and the consequent development of local circulations. In this study a field meteorological experiment was conducted to measure vertical structure of boundary layer during the period 25-29 June, 2007 at three locations Seabee base, Harrison and Wiggins sites in the Mississippi co...

An analysis of atmospheric gases and particles during periods of land and sea breezes in a coastal city in southwest Mexico indicates limited removal of total particle mass by deposition during periods when the air resides over the ocean. The average PM(2.5) mass concentrations for land and sea breeze samples were 25+/-1.0 and 26+/-1.0 microg m(-3), respectively. The average sum of the ion conc...

Recent developments have brought to the forefront some pressing and difficult problems concerning the usability of computer systems: lack of a satisfactory general purpose programming model for parallel computation; how to achieve efficient utilization of processing and memory resources; and system resilience in the presence of malicious attacks and the expectation that future hardware will be ...

[1] It is often assumed that ventilation of the atmospheric boundary layer is weak in the absence of fronts, but is this always true? In this paper we investigate the processes responsible for ventilation of the atmospheric boundary layer during a nonfrontal day that occurred on 9 May 2005 using the UK Met Office Unified Model. Pollution sources are represented by the constant emission of a pas...

A professional TV crew traveled to Gulf Breeze, Florida on two occasions in the spring of 1992 at a time when sightings were occurring on a weekly basis. On each occasion anomalous lights were observed and videotaped passing through the Gulf Breeze skies. This paper reports briefly on the first sighting and concentrates on the analysis of the second sighting when the TV crew used a special "hig...

City-scale warming is becoming a serious problem in terms of human health. Urban green spaces are expected to act as a countermeasure for urban warming, and therefore better understanding of the micro-climate benefits of urban green is needed. This study quantified the thermal influence of a large green park in Tokyo, Japan on the surrounding urban area by collecting long-term measurements. App...
