Soil moisture impacts on convective indices and precipitation over complex terrain

Barthlott, Christian ; Hauck, Christian ; Schädler, Gerd ; Kalthoff, Norbert ; Kottmeier, Christoph

In: Meteorologische Zeitschrift, 2011, vol. 20, no. 2, p. 185-197

The impact of soil moisture on convective precipitation, convective indices, surface energy balance components, and near-surface meteorological variables is analysed for seven intensive observation periods of the Convective and Orographically induced Precipitation Study (COPS) conducted in summer 2007 using a non-hydrostatic limited-area atmospheric prediction model. The control runs are compared...

Soil moisture variability and its influence on convective precipitation over complex terrain

Hauck, Christian ; Barthlott, Christian ; Krauss, Liane ; Kalthoff, Norbert

In: Quarterly Journal of the Royal Meteorological Society, 2011, vol. 137, no. S1, p. 42-56

Soil moisture monitoring data from the Convective and Orographically-induced Precipitation Study (COPS) 2007 are combined with operational and high-resolution simulations with the weather forecast system GME/COSMO-DE to analyse the discrepancies between observed and modelled soil moisture fields and their potential impacts on convective precipitation forecasts. We use data from the newly...

Within the framework of the international field campaign COPS (Convective and Orographically-induced Precipitation Study), a large suite of state-of-the-art meteorological instrumentation was operated, partially combined for the first time. This includes networks of in situ and remote-sensing systems such as the Global Positioning System as well as a synergy of multi-wavelength passive and active...
