Abstract: Hourly averaged winds from 30 m towers of the RAMS network (St. Louis region) are analyzed to determine systematic differences between urban and rural wind speed and direction. Previous studies of tower winds in London and ...

Abstract: From Regional Air Monitoring System (RAMS) tower data recorded in St. Louis during 1976, time series of convergence, heat island intensity and solar radiation are presented for five calm periods each exceeding 12 h. The ...

Abstract: Hourly averaged winds are computed from a one-year record taken atop five 10 m towers and four 30 m towers distributed over 4000 km2 of typical agricultural land. Vertical temperature differences are available from three ...

Abstract: A model is formulated which predicts the flux of a gaseous pollutant to a vegetational surface provided the surface concentration is known. The effect of canopy structure on the flux is accounted for in terms of height, ...

Abstract: Strong thunderstorm activity over Iowa on two successive afternoons was the apparent source of pressure-jump lines (PJL's) which moved SSE at 50 km h?1 through the nocturnal boundary layer and were detected by National ...
