Based on NOAA (National Oceanic and Atmospheric Administration) ERSSTv5 (Extended Reconstructed Sea Surface Temperature version 5) and monthly reanalysis data from NCEP(National Centers for Environmental Prediction)/NCAR(National Center for Atmospheric Research), the possible causes of the circulation anomalies related to the wide-range heat-wave events in summer (JJA, from June to August) 2022 over China are investigated by correlation, regression, composite analysis, and diagnosis of physical quantities. The results are shown below. (1) The SAH (South Asia high) in JJA 2022 is strong and extends eastward and westward, and the WPSH (western Pacific subtropical high) is also strong and extends westward. It is in phase of La Niña during summer 2022, but the vertical ascending circulations over the TA (tropical Atlantic) are stronger than those over the WP (western Pacific), and the vertical ascending circulations from the TIO (tropical Indian Ocean) to WP are also abnormally strong. (2) The combined effects of anomalous vertical circulations over TA, TIO, WP and La Niña result in the extreme abnormalities of SAH and WPSH in JJA 2022. La Niña and the abnormally strong vertical circulations from TIO to WP are helpful for the strengthening and westward expansion of SAH and WPSH. The abnormal vertical circulations over TA tend to help not only the strengthening and eastward expansion of SAH, but also the strengthening and westward expansion of WPSH. (3) The vertical circulations from TIO to WP mainly affect the circulation anomalies from the TP (Tibetan Plateau) to eastern China through local meridional Hadley circulation, characterized by the significant divergence anomaly from TP to eastern China in the mid- and low levels. However, the vertical circulations over TA can stimulate teleconnection wave train and then propagate downstream by causing zonal wind anomalies (jet stream anomalies), which then affect the circulation anomalies from TP to eastern China.
