APPLICATIONS OF WEATHER RADAR FOR THE ALLEVATION OF CLIMATIC HAZARDS

Objective



RESEARCH ON THE APPLICATION OF WEATHER RADAR DATA TO ALLEVIATE THE EFFECTS OF CLIMATIC HAZARDS WILL BE TACKLED ON THREE BROAD FRONTS.

FIRST, THE PROBLEM OF CALIBRATION IN DIFFERENT SYNOPTIC AND TOPOGRAPHIC SITUATIONS WILL BE ADDRESSED. THE CONVERSION OF RADAR SIGNALS TO RAINFALL ESTIMATES IS STILL NOT SATISFACTORY, AND THERE IS AN URGENT NEED TO UNDERSTAND THE VARIABILITY IN THE RELATIONSHIP IN ORDER TO DEVISE TECHNIQUES FOR IMPROVED CALIBRATION. THIS RESEARCH WILL FOCUS ON DATA FROM THE HAMELDON HILL RADAR IN LANCASHIRE WHICH WAS THE FIRST OPERATIONAL UNMANNED WEATHER RADAR IN THE UK.

SECOND, METHODS TO FORECAST EXTREME FLOODS AND THE PASSAGE OF POLLUTANTS THROUGH RIVER NETWORKS WILL BE EXAMINED THROUGH THE USE OF FORECASTING MODELS WHICH HAVE BEEN CONSTRUCTED ON A GRID SQUARE FRAMEWORK SUITABLE FOR USE WITH 2KM SQUARE WEATHER RADAR ESTIMATES OF RAINFALL. EVALUATION OF THESE MODELS USING REAL-TIME WEATHER RADAR DATA WILL BE COMPLEMENTED BY SENSITIVITY ANALYSES DESIGNED TO INVESTIGATE THE INFLUENCE OF SPATIALLY VARIABLE RAINFALL ON THE FLOOD HYDROGRAPH AND POLLUTOGRAPHS.

THIRD, THE IMPACT OF CLIMATIC HAZARDS IN URBAN AREAS WILL BE EXPLORED THROUGH A CASE STUDY OF URBAN AREAS IN NORTH-WEST ENGLAND. RESEARCH UNDER THIS HEADING WILL FOCUS ON SMALLER SCALE HAZARDS IN BOTH SPACE AND TIME WHICH HAVE GREATEST IMPACT IN URBAN AREAS. THE GREATER UNDERSTANDING GAINED WILL BE USED TO DEVELOP IMPROVED TECHNIQUES FOR THE OPERATIONAL MANAGEMENT AND DESIGN OF URBAN STORMWATER DRAINAGE SYSTEMS AND FOR POLLUTION CONTROL.
