This award will support the postdoctoral research of Dr. Jorge Chau at the Jicamarca Radio Observatory in Peru. The research has two parts: (1) the study of the east-west symmetry in 50 MHz radar echoes from the equatorial electrojet, and (2) the study of meridional variations in the E-region irregularities. For the first task, the investigators will examine whether or not the penetration of gravity wave energy associated with the nearby Andean Cordillera may play a role in sustaining the observed asymmetry in the radar echoes. For the second task, the investigators will use simultaneous measurements made with the Jicamarca radar and a 50 MHz wind profiler radar in Piura, Peru, about 1000 km north of Jicamarca. The researchers will look for possible differences in nighttime echoes in Piura related to the presence or absence of spread F over Jicamarca at magnetically connected locations in the ionosphere.

该奖项将支持豪尔赫·周博士在秘鲁希卡马卡射电天文台的博士后研究。 研究分为两部分：（1）研究赤道电急流50 MHz雷达回波的东西对称性;（2）研究E区不规则性的纬向变化。 对于第一项任务，研究人员将研究与附近安第斯山脉相关的重力波能量的渗透是否可能在维持雷达回波中观察到的不对称性方面发挥作用。 对于第二项任务，调查人员将使用在秘鲁的皮乌拉（Jicamarca以北约1 000公里）的Jicamarca雷达和50兆赫风廓线雷达同时进行的测量。 研究人员将寻找皮乌拉夜间回波中可能存在的差异，这些差异与电离层中磁连接位置处Jicamarca上方是否存在扩散F有关。
