“…Both of these parameters have been decreasing with time. Another study that focused on a subset of tropical Atlantic hurricanes, U.S. Gulf land-falling hurricanes, also showed no sign of increasing hurricane frequency or intensity over the period 1886 to 1995 (Bove et al 1998). Likewise, in regions of the northern Atlantic, there is interdecadal variation in the storm index but no centuryscale increasing or decreasing trend in storm roughness in the interval 1881 to 1995 (WASA Group 1998).…”

A review of the literature concerning the environmental consequences of increased levels of atmospheric carbon dioxide leads to the conclusion that increases during the 20th century have produced no deleterious effects upon global climate or temperature. Increased carbon dioxide has, however, markedly increased plant growth rates as inferred from numerous laboratory and field experiments. There is no clear evidence, nor unique attribution, of the global effects of anthropogenic CO 2 on climate. Meaningful integrated assessments of the environmental impacts of anthropogenic CO 2 are not yet possible because model estimates of global and regional climate changes on interannual, decadal and centennial timescales remain highly uncertain.

“…Landsea et al (1996) pointed out that there is actually a downward trend in the frequency of intense hurricanes in the Atlantic over the last five decades. More recently, Bove et al (1998a) also found no sign of an increase in the landfalling hurricanes in the Gulf of Mexico over the last century. Contrary to the above studies, Chan and Shi (1996) presented a different view regarding the long-term changes of the tropical storms and typhoons in the northwest Pacific.…”

Tropical cyclone activity (tropical depressions, tropical storms, and hurricanes combined) in the central North Pacific has been found to be on the rise and this increase amounts to about 3.2 cyclones over the last 32 years (1966-97). An examination of time series of tropical storms and hurricanes and hurricane records alone also reveals an increasing trend in both series since 1966. The upward trend is characterized by decadal-scale variability as manifested by fewer cyclones during the first half of the record (1966-81) and more during the second half of the record (1982-97). The maximum hurricane intensity has also increased in the central North Pacific, as well as the number of intense hurricanes from the first to the second half of the record. Relative to 1966-81, sea surface temperatures in the tropical Pacific and relative vorticity near the surface to the south of Hawaii have increased dramatically during 1982-97. The changes in the frequency and intensity of tropical cyclones in the central North Pacific appear to be modulated by decadal-scale variability of the basic state of SST, which transitioned from a cold to a warm phase in the late 1970s; this warm phase may have resulted in stronger and more frequent El Nino events as seen during the second half of the record, leading to more cyclones in the central North Pacific.

“…Klotzbach [20] also mentioned that there has been no increasing trend in accumulated cyclone energy (ACE) in each TC basin over the last 20 years (1990-2006) except for minor increase of ACE in categories 4-5 hurricanes. Bove et al [21] also discovered that there was no increasing trend in hurricane intensity landed on the Gulf of Mexico over the past century.…”

This study obtained the latitude where tropical cyclones (TCs) show maximum intensity and applied statistical change-point analysis on the time series data of the average annual values. The analysis results found that the latitude of the TC maximum intensity increased from 1999. To investigate the reason behind this phenomenon, the difference of the average latitude between 1999 and 2013 and the average between 1977 and 1998 was analyzed. In a difference of 500 hPa streamline between the two periods, anomalous anticyclonic circulations were strong in 30°–50°N, while anomalous monsoon trough was located in the north of South China Sea. This anomalous monsoon trough was extended eastward to 145°E. Middle-latitude region in East Asia is affected by the anomalous southeasterlies due to these anomalous anticyclonic circulations and anomalous monsoon trough. These anomalous southeasterlies play a role of anomalous steering flows that make the TCs heading toward region in East Asia middle latitude. As a result, TCs during 1999–2013 had higher latitude of the maximum intensity compared to the TCs during 1977–1998.
