“…On the other hand, an anomalous cyclone to the east of Taiwan steers typhoons northward away from Taiwan via anomalous southerly flows in its eastern section. Tan et al (2021) demonstrated a coherent dynamic relationship between the large-scale climatic anomalies and typhoon variability around Taiwan for the presatellite era. These results provide evidence for the adequateness of the 1900-1945 typhoon records compiled by the CWA to be used in interannual TC studies.…”

“…It is interesting to find a smaller mean for TC numbers around Taiwan in IE1 than IE2. Tan et al (2021) attributed the reduced TC numbers in IE1 to a colder climate suppressing TC genesis, a weakened WPSH facilitating TCs to recurve northward before approaching Taiwan, and the lack of satellite observations to detect TCs over a wider region.…”

“…Data in the period 1970-2015 are fully equipped with satellite-observed information, while no such information is included in the 1900-1945 data. Moreover, climatology in IE1 is evidently colder than IE2 (Tan et al, 2021) as a result of ongoing global warming. Due to differences in climatological states and satellite observations, interannual anomalies associated with El Niño years in IE1 and IE2 are calculated with regard to the climatological means of IE1 and IE2, respectively.…”

“…The major concern regarding pre‐satellite data is data uncertainty vis‐à‐vis reliability due to poor observational instruments and operations in those days. Recently, Tan et al (2021) examined interannual features of typhoon activity around Taiwan during 1900–1945. Years with active and inactive typhoon activity around Taiwan are categorized based on typhoon numbers compiled by the CWA.…”

Tropical cyclone (TC) activity around Taiwan is analysed via typhoon datasets compiled by the Central Weather Administration (CWA) for the pre‐satellite era of 1900–1945 (IE1) and the satellite era of 1970–2015 (IE2). Modulating processes imposed by El Niño years on active and inactive TC activity around Taiwan in the July–September season are examined and compared between IE1 and IE2. Analyses reveal coherent dynamic relationships between TC variability in Taiwan and large‐scale modulating processes; furthermore, modulating processes exhibit similar features between IE1 and IE2. El Niño years tend to have more (less) TC formation in the eastern (western) sector of the western North Pacific (WNP). In both IE1 and IE2, intensified TC activity around Taiwan is associated with northwestward TC tracks from the eastern WNP toward Taiwan assisted by a westward‐elongating cyclonic anomaly across the WNP and South China Sea. When a WNP cyclonic anomaly stretches northwestward toward oceans north of Taiwan, TCs from the tropical eastern WNP generally move northward toward oceans east of Taiwan to result in suppressed TC activity around Taiwan. The westward‐elongating anomalous cyclone is associated with an anomalous divergent centre over the Indian Ocean and an anomalous convergent centre in the tropical eastern Pacific over the 150°–130°W region. The northwestward‐extending anomalous cyclone connects with an anomalous divergent centre over the Maritime Continent and an anomalous convergent centre over the 130°–110°W region. Anomalous divergent and convergent centres displace westward (eastward) for active (inactive) TC types that are related to a more westward (eastward) maximum centre of anomalous warm waters in the tropical eastern Pacific. The above coherent dynamic relationships justify the reliability of TC records compiled by the CWA during IE1 and IE2.

Abstract: 2. TC-more years tended to have warm SST anomalies in the tropical central Pacific.3. The ISO had a positive effect to steer typhoon movements toward Taiwan.
