| description abstract | Aircraft measurements of liquid water content (LWC) made at sampling frequencies of 1 and 2 kHz with a particle volume monitor (PVM) probe from horizontal traverses in stratocumulus clouds during the Southern Ocean Cloud Experiment and cumulus clouds during the Small Cumulus Microphysics Study are described. The spectral density of the LWC measurements is calculated and compared to the ?5/3 scaling law. The effect of PVM sampling noise is found to be small in most cases. Most measurements follow approximately the ?5/3 law until cloud scales decrease below about 5 m in length. Below this length LWC variance can exceed that predicted by the ?5/3 law. It is suggested that the enhanced LWC variance at small scales is related to entrainment of environmental air into the clouds, which changes primarily the droplet concentration. | |
