Three-dimensional model simulations will be performed of storms during STERAO-A (Stratosphere-Troposphere Experiments: Radiation, Aerosols, and Ozone, 1996). The objectives of this field project were to examine trace gas transport, lightning production of nitrogen oxides (NOx), and photochemistry in convective storms. Events from the EULINOX (European Lightning NOx) project will also be simulated. The Goddard Cumulus Ensemble (GCE) model will be modified to allow nonuniform initial conditions and consideration of terrain. A 3-D cloud-scale chemical transport model will be constructed, to be driven by data fields generated by the 3-D cloud model. The CTM will include an advection scheme, a photochemistry solver and mechanism, a cloud-perturbed photolysis scheme, a lightning NOx parameterization algorithm, and a wet scavenging scheme. The characteristics of the observed cloud dynamics and microphysics will be replicated as closely as possible using the 3-D GCE model. Simulations will be conducted of the convective redistribution of trace gases within the thunderstorms. For lightning NOx, the approach observed flash rates and locations in the model will be used. The goal of the lightning analysis will be to better determine the amounts of NO produced per flash. This project is a collaboration with Kenneth Pickering, University of Maryland, College Park, ATM-9912336.

在Sterao-A期间，将对风暴进行三维模型模拟（平流层 - 对流层实验：辐射，气溶胶和臭氧，1996年）。该现场项目的目标是检查痕量气体传输，氮氧化物（NOX）的闪电产生以及对流风暴中的光化学。还将模拟Eulinox（欧洲闪电NOX）项目的事件。 将修改戈达德积分合奏（GCE）模型，以允许不一致的初始条件和对地形的考虑。将构建一个3-D云规模的化学传输模型，该模型由3-D云模型生成的数据字段驱动。 CTM将包括一个对流方案，光化学求解器和机制，云扰动的光解方案，闪电NOX参数化算法以及湿的清除方案。使用3-D GCE模型，将尽可能接近观察到的云动力学和微物理学的特征。模拟将进行雷暴内痕量的对流重新分布。对于Lightning NOX，将使用该方法观察到的闪存速率和模型中的位置。闪电分析的目的是更好地确定每次闪光灯产生的NO的量。 该项目与马里兰州大学公园的肯尼斯·皮克林（Kenneth Pickering）合作，ATM-9912336。
