Abstract:
At the National Meteorological Administration (NMA) the very short range forecasts for severe weather events are issued for a time period up to 6 hours. Thus, areas to convective storms development are identified, and for some parts of these areas, depending on the severity of severe weather events (e.g., large hail, severe wind gust, flash-floods), nowcasting warnings will be issued. The nowcasting and warning process for severe weather phenomena in Romania occurs in two steps: outlook and watch the available daily data and warning the severe phenomena. The present study represents an evaluation of the 5 years of severe weather warnings and is based on the warnings for the convective season (May to September) from 2003 until 2007 issued by the NMA. The aim of the study is to better understanding of the warning process, and the impact of these warning for the emergency-management authorities, media, and public. We have focused on warning for two severe weather events: precipitations, that can lead to flash-flood events, and wind that lead to property damage. Using ranked of these severe weather events based on the color coded severity used by NMA, we have studied the monthly and annual distribution of the warnings issued for the Bucharest area.
