Fig. 10From: A statistical analysis of medium-scale traveling ionospheric disturbances during 2014–2017 using the Hong Kong CORS networkCorrelation between cyclone pressure and DSTEC (a), azimuth (b), wavelength (c) and velocity (d). The black, blue, green and yellow circles represent the distance between the center of the cyclone and Hong Kong, which are 0–500 km, 500–1000 km, 1000–1500 km and 1500–2000 km, respectively, and the red curves correspond to the mean parameter values in each cyclone pressure valueBack to article page
