项目摘要

The Deep Convective Clouds and Chemistry (DC3) field campaign to be conducted May-June 2012 is a multi-regional, multi-platform effort to determine the impact of deep midlatitude continental convective clouds and their intrinsic dynamical, microphysical, and electrification processes upon upper tropospheric composition and chemistry. This award will support focused measurements in the Oklahoma-Texas subregion, but supported research will be conducted in close coordination with other studies focused on deep convective cloud-chemistry interactions along the Front Range of Colorado and in the southeastern U.S., allowing characterization of contrasting modes of convective behavior and background chemistry across these diverse regions. Support of this particular effort will facilitate data collection and analysis emphasizing mobile truck-mounted C- and X-band polarimetric radars capable of characterizing storm lifecycles within the context of lightning mapping array (LMA) observations and in coordination with overflight of DC3 aircraft especially instrumented for atmospheric chemistry measurements, viz. the NSF/NCAR GV high-altitude jet and NASA DC-8 platform.The intellectual merit of this research centers on comprehensive description of convective motions responsible for rapid transport of water substance and chemical constituents from the boundary layer up to the troposphere-stratosphere interface, as well as requisite microphysical interactions pivotal to cloud electrification and ensuing influences upon atmospheric chemistry. These measurements will be conducted within a region prone to development of especially long-lived and severe "supercellular" type thunderstorms. Broader impacts will come through graduate student education and a combination of media-based public and local school outreach, and ultimately through improved knowledge of the influence of deep atmospheric convection on the chemical composition of earth's atmosphere in the presence of natural and anthropogenic emissions.
2012年5月至6月进行的深对流云和化学(DC3)实地活动是一项多区域、多平台的努力,旨在确定深中纬度大陆对流云及其内在动力学、微物理和电气化过程对对流层上部组成和化学的影响。 该奖项将支持俄克拉荷马州-得克萨斯州次区域的重点测量,但支持的研究将与其他研究密切协调进行,这些研究侧重于沿着科罗拉多前线和美国东南部的深对流云化学相互作用,允许表征这些不同区域的对流行为和背景化学的对比模式。 对这一特殊努力的支持将促进数据收集和分析,重点是能够在闪电测绘阵列观测范围内表征风暴生命周期的移动的车载C波段和X波段偏振雷达,并与专门用于大气化学测量的DC3飞机的飞越协调,即NSF/NCAR GV高空喷气机和NASA DC-8平台。这项研究的智力价值集中在对流运动的全面描述上,对流运动是水物质和化学成分从边界层快速输送到对流层的原因-平流层界面,以及必要的微物理相互作用关键云电气化和随之而来的影响大气化学。 这些测量将在一个易于发展特别长时间和严重的"超细胞"型雷暴的区域内进行。 更广泛的影响将通过研究生教育和基于媒体的公共和地方学校宣传相结合来实现,最终通过提高对自然和人为排放存在时深层大气对流对地球大气化学成分影响的认识来实现。
