In situ measurements of the zonal and vertical components of neutral winds and the kinetic temperature being made by the DE-B Wind and Temperature Spectrometer (WATS) in the upper thermosphere provide the opportunity to gain new knowledge of polar region physics. On the basis of the data we have obtained to date we confirm that the global thermosphere wind distribution is primarily thermally driven over the earth from the mid-afternoon sector. The velocities range from tens to a few hundred meters per second. However, the polar cap and auroral region wind systems are highly dynamic with velocities as high as 1 km sec-1. They appear as superimposed on the thermally driven wind system. The polar regions zonal wind patterns appear to be generally in accord with the solar and anti-solar ion convection patterns previously observed and described by investigators in many publications. In addition we have observed vertical motions with velocity peaks from 100--250 m/sec-1 that frequently correlate well with peaks in the zonal component. Simultaneously observed exospheric kinetic temperatures show expected values at sub-auroral latitudes and variations of hundred of degrees in the polar regions. There are apparent correlations with vertical motions, but less obvious correlations with the winds' zonal components.
