Abstract:
In March 1990 the Met. Office invited the Thames and North-West Regions of the National Rivers Authority (NRA) to take part in a pilot operational service to receive and assess FRONTIERS rainfall forecasts. Funding was provided by the participants for the work they undertook, although the NRA did contribute an annual amount of 26K for their receipt and use of the forecast data in real-time. The trial period commenced on 1 st October 1990 with a duration of one year, later extended to 18 months. This work has been managed by the steering group given in Annex A (known as POSFFAG), who have compiled this report. The Project was undertaken both to evaluate rainfall forecast accumulations and to evaluate the derived flow forecasts using FRONTIERS forecast rainfall. The Report describes here the analysis undertaken to evaluate FRONTIERS forecast accumulations up to 6 hours ahead using rain-gauges, and an Isolated Event Model for selected catchments in London and the Lee Valley. Associated work on the use of FRONTIERS data with a transfer function model of the River Irwell catchment north of Manchester (Figure lb), and investigations of orographic precipitation enhancement over the Chilterns and North Downs, are also outlined.
