A simulation of this MCS was conducted using the Weather Research and Forecasting (WRF) model utilizing a 1 km nested grid centered over the quad-Doppler domain, along with 3 km and 9 km outer nests to capture progressively larger synoptic scale patterns.
The quad-Doppler analysis reveals that the convective line was oriented parallel to, and embedded within, the upper level jetstream. To assess the interaction between the MCS and jetstream, vertical cross sections orthogonal to the simulated convective line were analyzed, which indicate strong transport of low momentum air upward into the jetstream via the convective updraft. Such an interaction is clearly evident in the quad-Doppler analysis, as small scale deviations and eddies within the upper level jetstream are observed. An analysis of this complex interaction will be presented, complete with a discussion of possible feedbacks induced within the MCS and jetstream.
