I HAVE often felt surprised that the superiority in force of northerly and easterly as compared with southerly and westerly winds accompanying any given amount of barometric gradient has, at least ...

The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE. See: SOUND, SPEED OF SOUND. Compare: ACOUSTIC RADIATION. The levels of outdoor NOISE, whether they are intrusive or the normal ...

The air circulation, climate and weather system depend on the distribution of temperature over the surface of the earth. Atmospheric circulation is the large-scale movement of air by which heat is ...

This paper deals with the steady, frictionless, nonheatconducting flow field of a thin airfoil moving supersonically in an atmosphere with a weak wind gradient. Because of this wind gradient, the flow ...
