Low Altitude

Dispersion curves and stationary phase contributions to theoretical ground-pressure waves from low-altitude nuclear explosions are presented for model atmospheres containing winds. Comparison is made with previously published results. It is shown that the reflection of waves above an altitude of 120 km can result in certain effects in waves with periods greater than 5 minutes. These effects are readily observable in microbarographic records associated with nuclear explosions. It is shown that winds can have a pronounced effect on wave characteristics at periods between 1 and 10 minutes. It is concluded that the effects of low-atmospheric winds are best observed in the behavior of waves of periods less than 4 minutes. Details are given of the numerical procedures followed in obtaining results.

Maria Lugones

This paper strengthens the theoretical ground of feminist analyses of anger by explaining how the angers of the oppressed are ways of knowing. Relying on insights created through the juxtaposition of Latina feminism and Zen Buddhism, I argue that these angers are special kinds of embodied perceptions that surface when there is a profound lack of fit between a particular bodily orientation and its framing world of sense. As openings to alternative sensibilities, these angers are transformative, liberatory, and deeply epistemological.

A comparative study of joint distributions of wave height and period, as well as wave height and steepness, is presented. The analysis includes two theoretical joint distributions of wave height and wave period. These two distributions are transformed into joint distributions of wave height and wave steepness. The theoretical distributions are compared with measured data, as well as parametric models which are obtained by fitting to the data. The data used for comparison are relatively broad-banded and are obtained from measurements in deep waters on the Norwegian continental shelf. It is found that the theoretical distributions are inadequate to describe the joint distributions of the primary wave characteristics of these broad-band data, and thus it is suggested to use parametric models to describe such data. Finally, the engineering relevance of the joint distribution of wave height and wave steepness is discussed.
