Evaluations of Actual and Adjusted Wind–Pressure Relationship of Tropical Cyclone Using Aircraft-Assisted Best Track Data
The relationship between maximum sustained wind speed (Vmax) and minimum sea level pressure (Pmin) of tropical cyclones (TC), which is called the wind–pressure relationship (WPR), is investigated by using best track data in which aircraft observations are used. On average, for given Vmax (Pmin), Pmin (Vmax) varies by 8.5 hPa (11.0 kt) between the 25th and 75th percentiles, and it varies by 17.1 hPa (22.6 kt) between the 10th and 90th percentiles; corresponding variations in the Dvorak Current Intensity (CI) numbers are also quantified. Also investigated is an adjusted WPR in which environmental conditions are incorporated through multiple linear regression. Its utilization reduces the variations to 6.9 hPa (9.5 kt) between the 25th and 75th percentiles and 13.0 hPa (18.9 kt) between the 10th and 90th percentiles. These remaining variations indicate intrinsic variability of WPR, suggesting a need for further utilization of observations to improve the intensity estimation of TCs.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
