Abstract: The climatological occurrence of meteorological conditions associated with extensive and persistent arms of high air pollution potential over the western United States is presented. The most likely large-scale synoptic ...

Abstract: Mean radiosonde observations and normal maximum surface temperatures are used with the assumption of a dry adiabatic lapse rate to estimate monthly mean maximum mixing depths (MMD's) for 45 stations in the contiguous United ...

Abstract: This paper presents time cross-sections of vertical temperature structure during the 1966 Thanksgiving week air pollution episode in New York City, based on 6-hourly soundings at Kennedy Airport. The analyses depict numerous ...

Abstract: Daily estimates of morning and afternoon mixing depths and average wind speeds through the mixing layers were calculated and summarized for seven locations in several climatic regions of the contiguous United States. Mixing ...

Abstract: Daylight visibility observations at the Sacramento Municipal Airport were used to investigate the possibility that visibility in the area has been declining due to rising levels of air pollution. Those visibility observations ...

Abstract: The chemical analyses of particulate samples obtained by high-volume air-sampling instruments at remote sites near the California coast are shown to be related to trajectories of the sampled air. In particular, high-chloride ...

Abstract: The plume rise equations of Briggs (1975) for variable vertical profiles of temperature and wind speed are described and applied for hypothetical short and very tall chimneys at five National Weather Service rawinsonde ...

Abstract: Hourly surface wind-speed observations recorded over 2 yrs, at 16 Weather Bureau Airport Stations were studied to establish relationships between average daily speeds and the frequencies of individual hourly speeds. Only ...
