Sentence examples for latitude structure from inspiring English sources

The peak at 0 degrees quasi-dipole latitude is primarily due to the equatorial electric field strength, while the higher latitude structure is primarily due to the neutral wind field (Fambitakoye et al., 1976, p. 114).

The latitude structure at 90 km is shown in the upper panel and the height structure of the same wave over the equator is shown in the lower panel.

The observed latitude structure of O/N2 therefore imposes constraints on external sources of energy to the thermosphere ionosphere system, and is valuable information for use in physical models.

Figure 2 upper panel shows the latitude structure of the spectral amplitude of the 5.5-day Kelvin (E1) wave in temperature (in K°) at 90 km as obtained from the TIMED/SABER data for the period from 1 August to 31 October 2005.

This type of latitude structure is consistent with the first symmetric Hough function for DW1 plotted in Figure 2. The approximately 12-h shift in phase between the equator and ±20° −40° latitude in 'Additional file 1: Phases for Figure 6' support this interpretation.

On the other hand, D0 has minimum amplitudes near the equator, and its latitude structure is similar to that of the first antisymmetric mode of D0 plotted in Figure 2. As shown in 'Additional file 2: Phases for Figure 7', D0 is nearly in anti-phase between the N. and S. hemispheres and, moreover, does not change much throughout the year.

These components have latitude structures corresponding to the respective Hough functions calculated using the algorithm by Swarztrauber and Kasahara (1985).

Similar characteristics are also found for the altitude-latitude structure of Dw2 and Ds0.

In addition to the good agreement above 90 km, the altitude-latitude structure of De3 in August between 40 and 90 km (with amplitude <4 K) also compares well between the model and SABER.

In this section, we present the climatological altitude-latitude structures of the migrating component Dw1 and three nonmigrating components De3, Dw2, and Ds0 from both eCMAM30 and SABER.

The altitude-latitude structures for the four diurnal tidal components (Dw1, De3, Dw2, and Ds0) from the two datasets are also in very good agreement even for structures in the stratosphere with a weaker amplitude.
