| Zusammenfassung |
| We present a detailed meteorological analysis of the development of a heavy thunderstorm
affecting the South-East of Germany on 19 July 2007 by using the WRF model in a cloud
system resolving configuration.
A mesoscale convective system which originated over France in the night between 18 July
and 19 July, crossed Germany from West to East in the morning on 19 July. In
the early afternoon hours three strong cells developed at the Southern edge of the
system in the area of Nuernberg leading to heavy precipitation and causing severe
damage and even death. We investigated the importance of several meteorological
parameters such as the extraordinarily high CAPE for the initiation of convection at the
location of maximum cell development. Furthermore, we tested the sensitivity of
the storm development in the model simulations to different meteorological initial
conditions.
As part of the HOOVER/COPS/TRACKS campaign aircraft measurements of trace gases
were taken in the outflow region of these convective cells. The convective event which
occurred on 19 July 2007 shall be used as a case study to investigate convective transport of
trace gases as well as the importance of ice formation for the partitioning and distribution of
trace gases within a thunderstorm and the distribution of trace gases downwind of the storm. |
