Figure 6From: Global distribution of the migrating terdiurnal tide seen in sporadic E occurrence frequencies obtained from GPS radio occultationsTerdiurnal amplitude in zonal wind (upper row) and in vertical zonal wind shear (lower row). Shown are the results for January (left column) and April (right column), simulated by MUAM. The contour intervals are 2 m/s and 0.2 m/s/km, respectively.Back to article page
