美国海军研究实验室的三维模拟代码SAMI3/ESF被用于研究日落后电离层对圆形重力波的响应。我们将圆形（局地）和平面波（非局地）重力波与底部F层的耦合建模为触发赤道等离子体泡的一种机制。结果支持了非平面重力波比平面重力波能更强地与F层耦合这一假设。结果还表明，种子波与F层的耦合取决于（非局地）增长率以及种子波位置处的局地电子密度。
The Naval Research Laboratory three‐dimensional simulation code SAMI3/ESF is used to study the response of the postsunset ionosphere to circular gravity waves. We model the coupling of both circular (local) and plane wave (nonlocal) gravity waves to the bottomside F layer as a mechanism for triggering equatorial plasma bubbles. Results support the hypothesis that nonplane gravity waves can more strongly couple to the F layer than plane gravity waves. Results also show that the coupling of the seed wave to the F layer depends on the (nonlocal) growth rate and the local electron density at the position of the seed wave.
