The relationship between maximum sustained wind speed (V_max) and minimum sea level pressure (P_min) 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 V_max (P_min), P_min (V_max) 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.

利用飞机观测的最佳轨迹数据，研究热带气旋（TC）的最大持续风速（V _max）与最小海平面气压（P _min）之间的关系，即风压关系（WPR）。被使用。平均而言，对于给定的V _max ( P _min )，P _min ( V _max ) 在第 25 个百分位数和第 75 个百分位数之间变化 8.5 hPa (11.0 kt)，在第 10 个百分位数和第 90 个百分位数之间变化 17.1 hPa (22.6 kt)；德沃夏克电流强度 (CI) 数字的相应变化也被量化。还研究了调整后的 WPR，其中通过多元线性回归纳入环境条件。它的利用将第 25 个百分位数和第 75 个百分位数之间的变化减少到 6.9 hPa (9.5 kt)，将第 10 个百分位数和第 90 个百分位数之间的变化减少到 13.0 hPa (18.9 kt)。这些剩余的变化表明 WPR 的内在变异性，表明需要进一步利用观测来改进 TC 的强度估计。
