英文摘要 | A new approach is developed for estimating entrainment and detrainment rates in cumulus clouds based on aircraft observations. Equations relating entrainment and detrainment rates to gross entrainment and detrainment are derived. This approach is applied to the Holistic Interactions of Shallow Clouds, Aerosols, and Land-Ecosystems (HI-SCALE) field campaign, supported by the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) program. The results show that both entrainment and detrainment rates decrease with increasing height. Sensitivity tests with different detrained air assumptions yield similar results. The entrainment and detrainment rates can reproduce the cloud thermodynamic variables. Partial correlation analysis indicates that entrainment rate is positively correlated with environmental relative humidity, and detrainment rate is negatively correlated with environmental relative humidity and positively correlated with entrainment rate. This new approach can be applied to other cloud observations to obtain a dataset of entrainment and detrainment rates in cumulus clouds. |
