The data used in this article are: <br>(1) Sea level pressure field (SLP), zonal meridional wind field and vertical wind field data are all taken from NCEP/NCAR (NCEP1) daily average and monthly average reanalysis grid data , The resolution is 2.5º×2.5º (Kalnayetal., 1996). <br>(2) The sea surface temperature is obtained from the sea surface temperature data set of the Hadley Centre of the British Meteorological Service, with a resolution of 1º×1 (Rayner et al., 2003). <br>(3) Obtain the outward long wave emission (OLR) from NOAA/AVHRR data with a resolution of 2.5°x 2.5° (Liebmanm and Smith, 1996). <br>(4) The wind stress data superimposed in the numerical experiment is obtained from the ERA-Interim data of the European Center, with a resolution of 1º×1º (Dee et al., 2011). <br>The period of the above data is from 1979 to 2016, and the climatic conditions are the average level from 1979 to 2016. The ENSO event selection method is as follows: When the average sea surface temperature anomaly (SSTA) of the Niño3 zone (150°W-90°W, 5°S-5°N) in the winter half year is greater than or equal to 0.5°C, it is an ElNiño event, which is less than The LaNiña event is equal to -0.5°C. <br>A total of 8 El Niño events and 10 La Niña events were selected from 1979 to 2016 , as shown in Table 1. <br>Table 1 El Niño and La Niña events selected during 1979-2016

The data used in this article is:<br>(1) Sea level pressure field (SLP), longitude wind field and vertical wind field data are taken from the NCEP/NCAR (NCEP1) daily average and monthly average reanalysis grid data, the resolution is 2.5o×2.5o (Kalnayetal., 1996).<br>(2) Sea surface temperature is obtained from the Sea Surface Temperature Data Set at the Hadley Centre of the Met Office at a resolution of 1o ×1 (Rayner et al., 2003).<br>(3) Outward long-wave emission (OLR) from NOAA/AVHRR data with a resolution of 2.5 degrees x 2.5 degrees (Liebmanm and Smith, 1996).<br>(4) The wind stress data superimposed in the numerical experiment were obtained from the ERA-Interim data in the european center with a resolution of 1o ×1o (Dee et al., 2011).<br> The period above is 1979-2016, with climatic conditions averaged from 1979 to 2016. EnSO events are selected as follows: an El Niño event when the sea surface temperature level (SSTA) mean is greater than or equal to 0.5 degrees C in the mid-winter niño3 zone (150 degrees W-90 degrees W, 5 degrees S-5 degrees N), and a La Niña event when the average is less than or equal to -0.5 degrees C. In 1979-2016<br>A total of 8 El Niño events and 10 La Niña events were selected during this period, as shown in Table 1.<br>Table 1 El Niño and La Niña events selected during 1979-2016

The data used in this paper are:<br>(1) Sea level pressure field (SLP), zonal meridional wind field and vertical wind field data are obtained from NCEP / NCAR (ncep1) daily and monthly average reanalysis grid data with a resolution of 2.5 ° x 2.5 ° respectively (kalnay et al., 1996).<br>(2) Sea surface temperature was obtained from the HMS Hadley Center sea surface temperature dataset with a resolution of 1 ° x 1 (Rayner et al., 2003).<br>(3) Outgoing long wave emission (OLR) was obtained from NOAA / AVHRR data with a resolution of 2.5 ° x 2.5 ° (Liebmann and Smith, 1996).<br>(4) The superimposed wind stress data in the numerical experiments were obtained from era interim data in the European center, with a resolution of 1 ° x 1 ° in 2011 (DEE et al., 2011).<br>The period of the above data is from 1979 to 2016, and the climate condition is the average level from 1979 to 2016. The selection method of ENSO events is as follows: when the average SSTA of Ni  O 3 area (150 ° w-90 ° W, 5 ° S-5 ° n) is greater than or equal to 0.5 ℃, it is El  Ni  o event; when it is less than or equal to - 0.5 ℃, it is La  Ni  a event. In 1979-2016<br>A total of 8 El Ni ⁃ o Events and 10 La Ni ⁃ a events were selected, as shown in Table 1.<br>Table 1 selected El Ni NIA O and La Ni NIA events from 1979 to 2016<br>
