    Abstract

    In this study of drought in the southeast and south central England, precipitation records and a recently developed drought index are utilised to identify severe drought events over the past twenty-six years. This is a study of meteorological drought because it is based solely on precipitation records. However, intrinsic within the identification and isolation of these drought events is the concept of hydrological drought because rainfall accumulated over a six monthly period is analysed. Once drought sequences have been identified an analysis of the atmospheric circulation patterns based on the Lamb Jenkinson catalogue during these periods is undertaken in order to determine the main causes of meteorological drought hazard in the south of England over the past twenty-six years. Six major droughts have occurred and it was found that there were three main weather types dominating these six events. Comparisons with the southwest are made to assess the coincidence of drought events across the region. This research highlights the need for further investigation into why these atmospheric circulation situations causes drought in this region especially in the face of increasing climatic variability.
