| Zusammenfassung |
| The influence of different wind directions on
the outbreak of convection in Northern England, was investigated with a
high-resolution numerical model. The Clark model, a 3D finite-difference,
non-hydrostatic model was used in this study. It was initialised with the
topography of Northern England, a representation of surface characteristics, and
used a routinely available meteorological sounding, typical of the unstable
conditions. Results showed that convective cells were initially triggered in the
lee of the elevated terrain, and that only after the convection had developed,
were cells upwind of the elevated terrain produced. The windward slopes
themselves seemed sheltered from convection. Under most wind directions, the
central Pennines (the Forest of Trawden and the Forest of Rossendale) seemed
particularly affected by convective rainfall. |
