Abstract

Over the years, the Leipzig Wind Profile observed under near neutral condition has been considered as an essential benchmark for idealized friction layer models. However, the general weather condition for the Leipzig Wind Profile still remains a mystery after nearly 90 years. In order to simulate this event and try to recreate the weather conditions at that time, the WRF model driven by two types of reanalysis data setting up with two domains is launched. The model captures the wind physics well, except for a small deviation around 800 meters. Additionally, the simulated surface friction velocity and surface heat flux at Leipzig are close to the validation value. The simulated temperature slope at Lindenberg has some deviation compared to the documented value, which may be caused by the vertical coarse resolution and sensitive temperature fluctuations over the height. Moreover, there may have been rain or drizzle when the observation took place and this may have contributed to the near neutral condition feature. A finer resolution simulation could be run to investigate this further
