英文摘要: Quasi-two day wave propagating westward with wave number 1 (W1) in January 2017 is studied using global temperature observed by Sounding of the Atmosphere using Broadband Emission Radiometry and wind observed by a meteor radar at Fuke, China (19.0°N, 109.8°E). The amplitude of W1 significantly enhances during January 2017, when two stratospheric warming events occur. The temperature perturbation of W1 reaches maximum amplitude of more than 6 K at latitude ±15° around ~84 km and ~95 km. The structure of temperature W1 is symmetric with regard to the equator. The temporal variation of W1 is consistent with the stationary planetary wave with wave number 2 (SPW2), but contrary to the quasi-two day wave propagating westward with wave number 3 (W3). When SPW2 is large during two sudden stratospheric warming events, energy transfers from W3 to W1. Two bursts of the 2 day wave in meridional wind observed by the meteor radar are just corresponding to the local maxima of W3 and W1, respectively. We conclude that during January 2017, W1 is generated by the nonlinear interaction between SPW2 and W3. SPW2 which is modulated by the quasi-16 day perturbation in the stratosphere plays a key role in the energy transmission from W3 to W1, and it is responsible for the 16 day variation of W1. ©2018.
