Mixing Heights Wind Speeds And Potential For Urban Air Pollution Throughout The Contiguous United States written by George C. Holzworth and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1972 with Air categories.
The mixing-layer height and the average wind speed within the mixing layer were calculated twice for each day of a 5-year record of upper air observations at 62 National Weather Service stations int he contiguous United States. The times of day of these calculations are morning and mid-afternoon. A rough allowance was made for effects of the urban "heat island" on the morning mixing heights. The morning and afternoon times coincide approximately with those of maximum and secondary minimum concentrations of slow-reacting pollutants in cities. These calculations illustrate the typical large diurnal variation in atmospheric dispersion. Twenty charts present seasonal and annual, and morning and afternoon mean mixing heights and wind speeds. A model of some general dispersion features over urban areas is described in which the normalized pollutant concentration averaged over a city is a function of mixing height, wind speed, and city size (distance the wind travels across the city). Frequency values of mixing height by wind speed are used with the model to calculate average normalized concentration frequencies for each weather station. Thirty charts present isopleth analyses of seasonal and annual, and morning and afternoon normalized pollutant concentrations that were exceeded 10, 25, and 50 percent of the time for specified city sizes. The occurrence of episodes during which upper limits on mixing height and wind speed were not exceeded were determined from the daily morning and afternoon values of these parameters. Isopleths of the total number of episode-days for episodes lasting at least 2 days and at least 5 days with various limiting mixing-height and wind-speed values are presented in 20 charts.

MIL-STD-210A, 'Climatic Extremes for Military Equipment', is being revised. The revision will include two sets of windspeed design goals for military equipment being developed for worldwide usage over land: (1) the speed up to which 'operations' are expected to proceed, (2) the speed that equipment should 'withstand' without irreversible damage. A study of gustiness and variations of wind with height during strong wind regimes is presented. Nomograms of gust factor versus gust duration and steady windspeed are used to assign the most dynamically effective gust according to equipment dimensions. Based on a power-law relationship, factors for adjusting windspeed to a common height to describe windspeed and gusts over the vertical extent of military equipment usage are presented. Also included is a tabulation of wind statistics for selected stations considered in the search for worldwide wind extremes.

This book assesses wind engineering research studies in the past two decades to identify an interdisciplinary research agenda and delineate an action plan for evaluation of critical wind engineering efforts. It promotes the interdisciplinary approach to achieve collaborative research, assesses the feasibility of formalizing undergraduate wind engineering curricula, and assesses international wind engineering research activities and transfer approaches for U.S. applications.

Excerpt from Wind Pressures on Structures: Part I, General Discussion of Wind Pressure Data, Part II, Distribution of Pressure Over a Model of a Tall Building In considering the problem in its broad and general aspects, it resolves itself into two distinct questions. First, what are the maxi mum loads produced by the wind, and how often do they occur? This is the problem of the meteorologist and the aerodynamical physicist. Second, what are the stresses in the various members of the structure resulting from these 10 ads? This is a problem for the structural engineer, and no further mention will be made in this paper of this aspect of the problem except to call attention to the fact that various methods are -in use which give very different results for any particular member of the structure. (fleming's book.) We believe this division of the problem to be: a Vital one, for We see no hepe of advance unless the wind loads are investigated rather than the Wind stresses.
