Enhanced understanding of changes in tropical cyclones’ landfall frequency over mainland China
The climatological characteristics and interannual variations of tropical cyclones (TCs) making landfall in mainland China during the peak TC seasons (July–October) from 1980 to 2020 are examined using the China Meteorological Administration (CMA) best-track dataset. There were 270 TCs landfalling i...

| 520 | |a The climatological characteristics and interannual variations of tropical cyclones (TCs) making landfall in mainland China during the peak TC seasons (July–October) from 1980 to 2020 are examined using the China Meteorological Administration (CMA) best-track dataset. There were 270 TCs landfalling in mainland China during the study period, with 226 TCs landfalling in South China (SC) and 44 TCs landfalling in East China (EC). During 1980–2020, the number of TCs affecting mainland China gradually decreased, although the trend is not significant. The number of TCs impacting SC is experiencing a significant decrease, while the number of TC affecting EC is stable. Based on the change-point analysis, the TC landfall frequency in mainland China and SC incurred significant decreases in 1995/1996 and 1996/1997, respectively. The significant reduction in the number of landfalling TCs over SC and the insignificant reduction in the TC landfall frequency over mainland China are mainly due to the great reduction in the TC formation frequency over the western North Pacific (WNP). Meanwhile, the yearly mean of TCs’ landfalling latitudes is moving northward slightly, possibly linked to the slight poleward shift of their genesis locations. A large area of negative anomalies in the lower-tropospheric absolute vorticity and positive variations in the vertical wind shear (VWS) over the tropical WNP are possibly responsible for the reduction in TC genesis over the WNP. Moreover, the apparent opposite anomalies of the two variables over the region north of 20°N and south of 20°N might contribute to the slight poleward shift of genesis locations of landfalling TCs during the 41 years. The variations in the large-scale steering flow are favorable for more TCs moving northwestward and making landfall in EC than before. Meanwhile, the decrease in TC landfall frequency over mainland China is found to be significantly correlated to the pronounced warming over the tropical Indian Ocean. | ||

Meanwhile, the decrease in TC landfall frequency over mainland China is found to be significantly correlated to the pronounced warming over the tropical Indian Ocean. tropical cyclone landfall frequency mainland China South China East China Science Q Guangxin Li verfasserin aut Qinglan Li verfasserin aut Wei Zhao verfasserin aut Guanbo Zhou verfasserin aut Qifeng Qian verfasserin aut Chuanhai Qian verfasserin aut Lunkai He verfasserin aut Lunkai He verfasserin aut In Frontiers in Earth Science Frontiers Media S.A., 2014 10(2022) (DE-627)771399731 (DE-600)2741235-0 22966463 nnns volume:10 year:2022 https://doi.org/10.3389/feart.2022.932843 kostenfrei https://doaj.org/article/949e7e9e42074f20a6a5bef10391a98e kostenfrei https://www.frontiersin.org/articles/10.3389/feart.2022.932843/full kostenfrei https://doaj.org/toc/2296-6463 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ SSG-OLC-PHA GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_2003 GBV_ILN_2014 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 10 2022 |

There were 270 TCs landfalling in mainland China during the study period, with 226 TCs landfalling in South China (SC) and 44 TCs landfalling in East China (EC). During 1980–2020, the number of TCs affecting mainland China gradually decreased, although the trend is not significant. The number of TCs impacting SC is experiencing a significant decrease, while the number of TC affecting EC is stable. Based on the change-point analysis, the TC landfall frequency in mainland China and SC incurred significant decreases in 1995/1996 and 1996/1997, respectively. The significant reduction in the number of landfalling TCs over SC and the insignificant reduction in the TC landfall frequency over mainland China are mainly due to the great reduction in the TC formation frequency over the western North Pacific (WNP). Meanwhile, the yearly mean of TCs’ landfalling latitudes is moving northward slightly, possibly linked to the slight poleward shift of their genesis locations. A large area of negative anomalies in the lower-tropospheric absolute vorticity and positive variations in the vertical wind shear (VWS) over the tropical WNP are possibly responsible for the reduction in TC genesis over the WNP. Moreover, the apparent opposite anomalies of the two variables over the region north of 20°N and south of 20°N might contribute to the slight poleward shift of genesis locations of landfalling TCs during the 41 years. The variations in the large-scale steering flow are favorable for more TCs moving northwestward and making landfall in EC than before.

Enhanced understanding of changes in tropical cyclones’ landfall frequency over mainland China |
| abstract |
The climatological characteristics and interannual variations of tropical cyclones (TCs) making landfall in mainland China during the peak TC seasons (July–October) from 1980 to 2020 are examined using the China Meteorological Administration (CMA) best-track dataset. There were 270 TCs landfalling in mainland China during the study period, with 226 TCs landfalling in South China (SC) and 44 TCs landfalling in East China (EC). During 1980–2020, the number of TCs affecting mainland China gradually decreased, although the trend is not significant. The number of TCs impacting SC is experiencing a significant decrease, while the number of TC affecting EC is stable. Based on the change-point analysis, the TC landfall frequency in mainland China and SC incurred significant decreases in 1995/1996 and 1996/1997, respectively. The significant reduction in the number of landfalling TCs over SC and the insignificant reduction in the TC landfall frequency over mainland China are mainly due to the great reduction in the TC formation frequency over the western North Pacific (WNP). Meanwhile, the yearly mean of TCs’ landfalling latitudes is moving northward slightly, possibly linked to the slight poleward shift of their genesis locations. A large area of negative anomalies in the lower-tropospheric absolute vorticity and positive variations in the vertical wind shear (VWS) over the tropical WNP are possibly responsible for the reduction in TC genesis over the WNP. Moreover, the apparent opposite anomalies of the two variables over the region north of 20°N and south of 20°N might contribute to the slight poleward shift of genesis locations of landfalling TCs during the 41 years. The variations in the large-scale steering flow are favorable for more TCs moving northwestward and making landfall in EC than before. Meanwhile, the decrease in TC landfall frequency over mainland China is found to be significantly correlated to the pronounced warming over the tropical Indian Ocean. |

The climatological characteristics and interannual variations of tropical cyclones (TCs) making landfall in mainland China during the peak TC seasons (July–October) from 1980 to 2020 are examined using the China Meteorological Administration (CMA) best-track dataset. There were 270 TCs landfalling in mainland China during the study period, with 226 TCs landfalling in South China (SC) and 44 TCs landfalling in East China (EC). During 1980–2020, the number of TCs affecting mainland China gradually decreased, although the trend is not significant. The number of TCs impacting SC is experiencing a significant decrease, while the number of TC affecting EC is stable. Based on the change-point analysis, the TC landfall frequency in mainland China and SC incurred significant decreases in 1995/1996 and 1996/1997, respectively. The significant reduction in the number of landfalling TCs over SC and the insignificant reduction in the TC landfall frequency over mainland China are mainly due to the great reduction in the TC formation frequency over the western North Pacific (WNP). Meanwhile, the yearly mean of TCs’ landfalling latitudes is moving northward slightly, possibly linked to the slight poleward shift of their genesis locations.
