The NCEP/NCAR reanalysis data and the tropical cyclone best-track data which is compiled by Shanghai Typhoon Institute of China Meteorological Administration from 1949 to 2016 are used to study the relationship between atmospheric Circumglobal Teleconnection (CGT) and the frequency of landfall Tropical Cyclone (TC) on the mainland China during summer. Based on the Empirical Orthogonal Function (EOF) of 200 hPa meridional wind, CGT is defined by the first EOF pattern and its time factor is defined as Circumglobal Teleconnection Index (CGTI). CGT has five anomalous centers in middle latitudes of the Northern Hemisphere. CGTI shows a downward trend from 1949 to 2016 and has a periodic variation lasting two to three years. CGT is closely related to large-scale circulation anomalies. The result shows that there is negative correlation between CGTI and the TC frequency. In other words, the TC frequency is increasing during negative anomalous years, and vice versa. When CGT shows positive phase, the East Asian subtropical westerly jet intensifies, and the enhancement of anticyclonic shear on the southern side of the jet stream strengthens the divergence at 200 hPa around TC activity area during its landing process. Moreover, the intensification of Rossby wave energy propagating southward in troposphere leads to the convergence of wave flux, and therefore easterly anomaly appears in the corresponding region. Both of the above results in the easterly anomalous steering flow and vertical shear of zonal wind, thus increasing the possibility of TC landing in mainland China.
