“…Previous studies have suggested that ENSO has an important impact on the TC genesis frequency in the SEWNP and NWWNP (Lander, 1994;Chen et al, 1998;Wang and Chan, 2002;Elsner and Liu, 2003;Chu, 2004;Camargo et al, 2007;Kim et al, 2011;Zhan et al, 2011;Song et al, 2022). However, few studies have focused on the influence of solar activity on TC genesis frequency in the WNP.…”

“…Previous studies have verified that ENSO plays an important role in TC genesis frequency in the SEWNP and NWWNP (Lander, 1994;Chen et al, 1998;Wang and Chan, 2002;Elsner and Liu, 2003;Chu, 2004;Camargo et al, 2007;Kim et al, 2011;Zhan et al, 2011;Song et al, 2022). The researchers suggested that El Niño contributes to the increase of TC genesis frequency in the SEWNP and the decrease in the NWWNP, while the effect of La Niña is roughly opposite.…”

“…To sum up, TCs generated in the SEWNP have the longest lifetime and the greatest strength, while the TC genesis frequency in the NWWNP is the highest. Furthermore, ENSO has a great influence on the TC genesis in the SEWNP and NWWNP (Lander, 1994;Chen et al, 1998;Wang and Chan, 2002;Elsner and Liu, 2003;Chu, 2004; Frontiers in Earth Science frontiersin.org Camargo et al, 2007;Kim et al, 2011;Zhan et al, 2011;Song et al, 2022). Therefore, it is of great significance to study the TC genesis in the SEWNP and NWWNP, which is the focus of our analysis below.…”

“…TC genesis has attracted considerable attention, but its prediction has been a difficult topic for the past few decades (Cao et al, 2022). The western North Pacific (WNP) is known to be the most prolific tropical cyclone basin, accounting for about 1/3 of all the global TCs (Chan, 2005;Huang and Chen, 2007;Woodruff et al, 2013), and the southeastern part of the WNP (SEWNP) is an important key region for the TC genesis (Wang and Chan, 2002;Camargo and Sobel, 2005;Zhang et al, 2017;Liu et al, 2019;Shan and Yu, 2021;Cao et al, 2022;Song et al, 2022). Zhang et al (2017) found that the Atlantic meridional mode affects TC activity in the WNP mainly through changes in the TC genesis in the SEWNP.…”

“…As the most significant signal of interannual variability in the coupled atmosphere-ocean system, El Niño-Southern Oscillation (ENSO) plays a crucial role in TC genesis in the WNP (Pan, 1982;Chan, 1985;Li, 1987;Lander, 1994;Chen et al, 1998;Chan, 2000;Wang and Chan, 2002;Elsner and Liu, 2003;Chu, 2004;Camargo et al, 2007;Kim et al, 2011Kim et al, , 2016Zhan et al, 2011;Wang et al, 2014;Zhao and Wang, 2019;Song et al, 2022). A general consensus is that the relationship between ENSO and TC genesis frequency is weak in the entire WNP, but ENSO remarkably affects the shift of TC genesis location.…”

This study analyzes the frequency characteristics of tropical cyclone (TC) genesis in the southeastern part of the western North Pacific (SEWNP) during June–November from 1965 to 2019 and investigates the possible combined effect of the solar activity and El Niño-Southern Oscillation (ENSO). Results suggest that TCs generated in the SEWNP have the longest lifetime and greatest strength, and its frequency has apparent interannual and decadal variations, which is jointly affected by the solar activity and ENSO. In El Niño years during declining phases of solar cycle (1–3 years following the solar maximum), positive TC genesis frequency anomalies in the SEWNP are significantly strong and tend to occur in extremes. While the opposite is true for La Niña during ascending phases of solar cycle (1–3 years following the solar minimum). However, there exists no significant feature in the combined effect of La Niña (El Niño) and declining (ascending) phases of solar cycle. When declining (ascending) phases of solar cycle and El Niño (La Niña) are combined, the overlapping effect leads to apparently warmer (colder) sea surface temperature (SST) anomalies in the central equatorial Pacific and colder (warmer) SST anomalies in the western Pacific, so the SST anomalies gradient are stronger. It enhances low-level westerly (easterly) wind anomalies and upper-level easterly (westerly) wind anomalies, which is favorable for the further decrease (increase) of the vertical wind shear in the eastern (most) part of SEWNP. Moreover, the stronger and more westward low-level convergence (divergence) center appears in the Pacific, causing stronger low-level convergent (divergent) flow and upper-level divergent (convergent) flow anomalies, and strengthened (suppressed) ascending movement anomalies in the SEWNP. As a result, the TC genesis frequency in the SEWNP is much higher (lower). Further diagnoses show that absolute vorticity plays a leading role in El Niño years during declining phases of solar cycle, and its contribution is obviously much greater than other environmental factors. It is not perfectly symmetrical in La Niña years during ascending phases of solar cycle when the contribution of absolute vorticity is the greatest, but vertical wind shear is also important.
