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：
SOLA (Scientific Online Letters on the Atmosphere) is a peer-reviewed, Open Access, online-only journal. It publishes scientific discoveries and advances in understanding in meteorology, climatology, the atmospheric sciences and related interdisciplinary areas. SOLA focuses on presenting new and scientifically rigorous observations, experiments, data analyses, numerical modeling, data assimilation, and technical developments as quickly as possible. It achieves this via rapid peer review and publication of research letters, published as Regular Articles.
Published and supported by the Meteorological Society of Japan, the journal follows strong research and publication ethics principles. Most manuscripts receive a first decision within one month and a decision upon resubmission within a further month. Accepted articles are then quickly published on the journal’s website, where they are easily accessible to our broad audience.
