The parametric model with a single meteorologic
factor that had the best overall fit considering all three criteria--greatest proportion of deviance explained, smallest first-order autocorrelation, and largest correlation of raw and predicted values on hot days--included linear, quadratic, and cubic terms for maximum heat index on the same day and previous 3 days (lags 0-3; Table 2).
data for the sample collection dates were obtained from the Japan Meteorological Agency.
data (obtained from the German Weather Service/Climate and Environmental Evaluation) indicated that from December 1995 through April 1996, the wind blew from the northwest (from the direction of the large sheep farm toward Rollshausen) an average of 17 days per month.
We calculated Spearman correlation coefficients for the pollutant and meteorologic
data to investigate the relationships among these variables over the study period.
We thank the Department of Microbiology, Queen Mary Hospital, for providing reference laboratory data; Broadleaming Ltd and participating primary schools for providing absenteeism data; the Hong Kong Observatory for providing meteorologic
data; and Jacco Wallinga for helpful discussions about the method for estimating R.
Traffic pollution generated within a 3-km radius of each mother's residence was estimated using a comprehensive dispersion model that incorporated meteorologic
variables (such as atmospheric stability and wind), roadway geometry, traffic counts, and vehicle emission factors.
data from January 20 to February 15 showed unsuitable weather conditions for BTV replication in outdoor midges at the time of BTV transmission; daily minimum temperatures were 7.
Information on natural disaster-related morbidity and mortality is available from many sources, including medical examiners' and coroners' reports, death certificates, the American Red Cross, meteorologic
services, police and fire departments, and emergency medical services (3-5).
1494) review information sources that will be used to determine exposures in Queens, New York (one of seven NCS pilot study locations), including existing national, regional, and local databases with information on air and water quality, waste sites, toxics emissions and spills, dietary intakes, pesticide use, geographic features, land cover and land use, meteorologic
data, and other characteristics.
Because of compensation after the vernal equinox of more light in the North, the beginning of meteorologic
spring and summer differs no more than 1 month between cultivation zones (www.
Background: Airborne emissions from numerous point, area, and mobile sources, along with stagnant meteorologic
conditions, contribute to frequent episodes of elevated air pollution in Houston, Texas.
Natural disasters, particularly meteorologic
events such as cyclones, hurricanes, and flooding, can affect vector-breeding sites and vectorborne disease transmission.
