“…Because, on average, the P E in the NA is higher than in WNP (Atkinson and Holliday 1977), then for a given MWS, the R4 of tropical cyclones whose WPR satisfy the NA D-WPR are expected to be smaller than those satisfying the WNP D-WPR.…”

“…In KZ07, mention is made of the Atkinson and Holliday (1977) wind-pressure relationship adopted by the Regional Specialized Meteorological Center (RSMC), situated on La Réunion Island (overseas department of France) for use in the SWIO. But as no mention is made of this Atkinson and Holliday WPR in Dvorak (1984), and to avoid confusion for users of the SWIO tropical cyclone operational plan, the WPR included in Dvorak (1984) for use in the western North Pacific (WNP) is referred to as the WNP D-WPR.…”

In their study on the wind-pressure relationship (WPR) that exists in tropical cyclones, Knaff and Zehr presented results of the use of the Dvorak Atlantic WPR for estimating central pressure and maximum wind speed of tropical cyclones. These show some fairly large departures of estimated central pressure and maximum surface winds from observed values. Based on a study carried out in the southwest Indian Ocean (SWIO), it is believed that improvements in the use of the Dvorak WPR can be achieved by using the size of a closed isobar (it is the 1004-hPa closed isobar in the SWIO) to determine whether to use the North Atlantic (NA), the western North Pacific (WNP), or a mean of the NA and WNP Dvorak WPR for estimating central pressure and maximum wind speed in tropical cyclones.

“…Records with intensity weaker than tropical storms (TS) were excluded from our analysis since the analysis of tropical depressions is more subjective, especially for the cases that never developed into TSs. Additionally, although the most famous wind-pressure relationship in the western North Pacific was documented by Atkinson and Holliday (1977), it is unstable in early and late TC seasons, as well as for the cases of midget TCs (Chip Guard, personal communication). Therefore, the JMA's designations of storm categories were used in the following analysis rather than being determined from the sustained wind measurements that were taken before 1977.…”

The quality of tropical cyclone (TC) best track data has increasingly received more attention in climate research in recent years because of the rising interest in the possible effects of global warming on TC activity. In this paper, three best track datasets for the western North Pacific TCs were compared in a seasonal context. Firstly, the statistical characteristics were examined based on their distributions. Then, the potential impact of particular features within the datasets was evaluated by using contrastive cluster analyses.The mean amplitude of the annual cycle in the Japan Meteorological Agency (JMA) data is largest among the three datasets. The smallest interannual variability helped the Shanghai Typhoon Institute of China Meteorological Administration (CMA-STI) dataset to resist the negative effect of outliers. An inhomogeneity around 2003-2004 was identified in the Joint Typhoon Warning Center (JTWC) data by the outliers and was compared with the JMA and CMA-STI data.By using contrastive cluster analyses, the differences among the datasets and some effects related to particular issues, including the representation of the annual cycle, the outliers, and wind conversion were evaluated. The JTWC dataset is affected by outliers and wind conversion among the different average times, whereas the representation of the annual cycle was important for the CMA-STI data. After excluding all the outliers, the results indicated more consistent classifications of the TC annual cycle between the JMA and JTWC data.

“…The mean wind speed data were obtained from the Bureau of Meteorology's TC module database which derives data from the cyclone advisories issued by the responsible agencies. The minimum pressures were estimated using the relationship of Atkinson and Holliday (1977) adopted by the Australian TC module team. Climatological numbers are from Cooper and Falvey (2009) for the northwest Pacific and southern hemisphere and Mandal (1991) for the Bay of Bengal.…”
