摘要: The Horizontal Wind Model (HWM) has been updated in the thermosphere with new observations and formulation changes. These data are ground-based 630 nm Fabry-Perot Interferometer (FPI) measurements equatorial polar regions, as well cross-track winds from Gravity Field Steady State Ocean Circulation Explorer (GOCE) satellite. GOCE wind provide valuable twilight regions. FPI fill latitudinal gaps prior observational database. Construction of this reference model also provides opportunity to compare these measurements. resulting update (HWM14) an improved time-dependent, observationally based, global empirical specification upper atmospheric general circulation patterns migrating tides. In basic agreement existing accepted theoretical knowledge circulation, additional calculations indicate that specifications self-consistent climatological ionosphere plasma distribution electric field patterns.
