Longitudinal variations in the hydroxyl emission: 1. Temperature.

- Abstract
Data on longitudinal variations in the hydroxyl emission have been obtained based on long-term studies of the mesopause temperature and hydroxyl (OH) emission at different ground stations in the Northern Hemisphere and based on temperature measurements on the UARS WINDII satellite. Maximums at longitudes of Eurasia and North America and minimums over the Pacific and Atlantic oceans have been revealed in the global longitudinal temperature distribution. The average longitudinal temperature values show distinct seasonal variations. Local nonstationary large-scale inhomogeneities in the form of temperature maximums and minimums up to 30 K relative to the average temperature, correlating with the variations in the irregularity dimensions reaching several tens of degrees in longitude and latitude (which corresponds to several thousand kilometers), exist against a background of the average global temperature variation, reflecting the surface topography.
