摘要

利用地球静止业务环境卫星-16(GOES-16)高级基线成像仪(ABI)的亮度温度(TB)观测数据,研究了飓风 "艾玛"(2017 年)在 2017 年 9 月 4 日 6 时至 18 时(协调世界时)快速增强期间受对流影响的结构的时间演变。ABI 观测结果表明,源自 "艾玛 "眼球的椭圆眼和螺旋雨带都明显表现出波长-2 TB 不对称。9 月 4 日世界协调时 8 点 15 分至 10 点 05 分,椭圆眼以波长为 2 的涡旋罗斯比边缘波的平均速度逆时针旋转。在随后的约 2 小时内(协调世界时 9 月 4 日 10 时 25 分至 12 时 55 分),一个内螺旋雨带从眼球开始传播,其相位速度近似于根据飞机侦察数据计算出的涡旋罗斯比波(VRW)相位速度。在 "艾玛 "的 RI 期间,ABI TB 观测结果表明,眼内时而出现低 TB 入侵,伴随着波数为 1 和 2 的眼球 TB 不对称相位锁定,以及类似于 VRW 的内螺旋雨带从眼球向外传播。相位锁定导致艾玛的眼球不对称能量增长。虽然 9 月 4 日世界协调时 1415 点至 1725 点期间,艾玛的眼仍然是晴朗的,但源自一个大对流区的内螺旋雨带也有类似 VRW 的向外传播,这可能是由于艾玛的垂直倾斜造成的。这项研究表明,对流敏感的 GOES 成像仪观测数据与飓风动力学之间存在潜在联系。

GOES-16 ABI Brightness Temperature Observations Capturing Vortex Rossby Wave Signals during Rapid Intensification of Hurricane Irma (2017)

Geostationary Operational Environmental Satellite-16 (GOES-16) Advanced Baseline Imager (ABI) observations of brightness temperature (TB) are used to examine the temporal evolutions of convection-affected structures of Hurricane Irma (2017) during its rapid intensification (RI) period from 0600 to 1800 UTC 4 September 2017. The ABI observations reveal that both an elliptical eye and a spiral rainband that originated from Irma’s eyewall obviously exhibit wavenumber-2 TB asymmetries. The elliptical eye underwent a counterclockwise rotation at a mean speed of a wavenumber-2 vortex Rossby edge wave from 0815 to 1005 UTC 4 September. In the following about 2 hours (1025–1255 UTC 4 September), an inner spiral rainband originated from the eyewall and propagated at a phase speed that approximates the vortex Rossby wave (VRW) phase speed calculated from the aircraft reconnaissance data. During the RI period of Irma, ABI TB observations show an on–off occurrence of low TB intrusions into the eye, accompanying a phase lock of eyewall TB asymmetries of wavenumbers 1 and 2 and an outward propagation of VRW-like inner spiral rainbands from the eyewall. The phase lock leads to an energy growth of Irma’s eyewall asymmetries. Although the eye remained clear from 1415 to 1725 UTC 4 September, an inner spiral rainband that originated from a large convective area also had a VRW-like outward propagation, which is probably due to a vertical tilt of Irma. This study suggests a potential link between convection sensitive GOES imager observations and hurricane dynamics.
