Abstract: Differences in the temperature fields through the lowest 700 m of the atmosphere in and around New York City during the hours near sunrise are analyzed. Data were obtained by an instrumented helicopter on 42 predetermined ...

Abstract: A two-dimensional, non-steady model of the flow over an infinitely wide, warm, rough city is presented. The model consists of two layers, a lower analytical constant-flux layer, and an upper finite-difference transition ...

Abstract: Month-to-month variations in the early morning surface-based and near-noon elevated inversions at San José, Calif., were determined from slow rise radiosondes launched during a four-year period. A high frequency of shallow, ...

Abstract: Data obtained from the extensive mesoscale anemometer network established during the New York University Urban Air Polution Dynamics Program were used to study the effects of New York City on frontal movement. Frontal ...

Abstract: The two?dimensional, non-steady URBMET urban boundary layer model was integrated on a variable and staggered grid, with time?splitting and a donor cell advection scheme. Simulations for periods of up to 14 h of meteorological ...

Abstract: Meteorological and air-quality data, as well as surface tracer concentration values, were collected during 1990 to assess the impacts of Navajo Generating Station (NGS) emissions on Grand Canyon National Park (GCNP) air ...

Abstract: Temporal changes in the spatial distribution of sulfur dioxide concentrations in New York City resulting from the passage of sea breeze and synoptic fronts were studied using data from the New York University/New York City ...

Abstract: Multiply nested urbanized mesoscale model [Coupled Ocean?Atmosphere Mesoscale Prediction System (COAMPS)] simulations of the New York?New Jersey metropolitan region are conducted for 4?11 July 2004. The simulations differ ...

Abstract: his study investigates interactive effects from the Beijing urban area on temperature, humidity, wind speed and direction, and precipitation by use of hourly automatic weather station data from June to August 2008?12. ...
