Investigation of Microphysical Properties of Deep Convective Systems using Aircraft in-situ and Ground-based Measurements during MC3E
Abstract
Hydrometeors in deep convective clouds can vary significantly from developing stage to dissipating stage, and can be also very different within convective core, stratiform rain and anvil regions. However, the microphysical properties of these systems are one of the most difficult tasks for retrieval from both active and passive remote sensing instruments. The Midlatitude Continental Convective Clouds Experiment (MC3E) provides a unique opportunity to bring the multi sensors and multi platforms to measure the detailed structures of such systems. In this study, we will investigate the microphysical properties of deep convective systems (DCSs) by combining the aircraft in-situ measurements and various ground radar observations. Most importantly, we can examine the microphysics in the convective, stratiform rain and anvil regions of DCSs based on the classifications of Feng et al (2011), and further study the variations of cloud microphysics among developing, mature, dissipating stages based on a satellite tracking method (Feng et al 2012). One of our anticipated outcomes from this study will provide a "cloud-truth" dataset for Midlatitude DCSs. Through the way of case studies during MC3E, we will perform detailed comparisons of convective cloud properties observed by the ARM new instrumentation and aircraft with the Feng et al. (2011, 2012) results.
