摘要

本文报道了一种基于热气球运动的风观测方法。通过与荷兰Cabauw气象塔2018年5 - 9月的风观测数据进行对比,得到的纬向风分量和经向风分量的误差标准差分别为σu=0.65ms−1 $$ {\sigma}_u=0.65\;{\mathrm{ms}}^{-1} $$和σv=0.69ms−1 $$ {\sigma}_v=0.69\;{\mathrm{ms}}^{-1} $$。随后与HARMONIE - AROME模型短期预报的比较显示,风矢量差的标准偏差为2.5 ms−1。从HAB观测集中选取了一个快速变化的风场属于小型强化低气压的病例。将赤潮风观测应用于资料同化,作为单次观测实验的原理证明。结果表明,在复杂斜压情况下,模型状态略有改善。

Wind observations from hot-air balloons and the application in an NWP model

In this paper, we report on a wind observation method based on the movement of hot-air balloons (HABs). A quality assessment was carried out by comparing against wind observations at the meteorological tower of Cabauw in the Netherlands during May–September 2018, and the obtained standard deviations in error were σ u = 0.65 ms 1 $$ {\sigma}_u=0.65\;{\mathrm{ms}}^{-1} $$ and σ v = 0.69 ms 1 $$ {\sigma}_v=0.69\;{\mathrm{ms}}^{-1} $$ for the measured zonal and meridional wind components, respectively. Subsequent comparison against short-term forecasts of the HARMONIE-AROME model showed a standard deviation of 2.5 ms−1 for the wind vector difference. From the HAB observation set, a case was selected with a rapidly changing wind field belonging to a small intensifying depression. The HAB wind observation was applied in data assimilation as a proof of principle for a single-observation experiment. It is shown that in a complex baroclinic situation, the model state is slightly improved.
