The model uses as input data pressure surface heights measured at periods of the year when the stratospheric polar vortex exhibits .nearly circular patterns around the pole. The components of the polar wind velocities that result from a Prandtl eddy viscosity distribution are found to be in general agreement with those obtained by other investigators.^

Endangered Southern Resident killer whales inhabit areas including the urban coastal waters of Puget Sound near Seattle, WA, where anthropogenic sounds are ubiquitous, particularly those from motorized vessels. A calibrated recording system was used to measure killer whale call source levels and background noise levels (1-40 kHz). Results show that whales increased their call amplitude by 1 dB for every 1 dB increase in background noise levels. Furthermore, nearby vessel counts were positively correlated with these observed background noise levels.

The influence of these meteorological parameters on the SO2 concentrations has been investigated by a statistical analysis of the daily average SO, values measured at six locations in the Athens basin for the six years from 1974 to 1979. Wind speed, minimum temperature and amount of rain has been found to control SOz concentrations during the cold season while wind speed, wind direction and relative humidity are central in the warm season. Based on this, multiple regression models, both linear and non-linear, for the prediction of the next day's SO, concentration have been derived that explain more than 50 7; of the data variance. Further improvements on the modelling are contingent on the availability of boundary layer structure data and on details of the local wind field. The meteorology of high concentration episodes has also been examined and the synoptic characteristics for the onset and end of such episodes have been identified. Finally, discriminant analysis classification functions, utilizing forecast meteorological variables have been obtained which are capable of predicting accurately the occurrence of high pollution concentrations.

The level inside the home also depends on the location of the home (urban, suburban, or rural). Bathrooms and kitchens show heavier particle fallout than living rooms or bedrooms.

The production rates relative to the single-nucleon interactions of K- are R(K-d-->Sigma-p)=(0.505+/-0.036)%, R(K-d-->Sigma0n)=(0.337+/-0.070)%, and R(K-d-->Lambdan)=(0.387+/-0.041)%. The ratio of the rates R(K-d-->Sigma-p) and R(K-d-->Sigma0n) is consistent with the prediction of isotopic-spin invariance for the strong interactions. The total two-nucleon production rate is
