| Popis: | A classification scheme for nor'easters and other winter storms (November-April) in the eastern and central United States provides real-time information on the potential impact of these storms. This scheme also may be applied to winterstorms over the last century to provide a time series of trends and cycles in specific magnitude nor'easters along the East Coast and Colorado lows that migrate northward toward the Great Lakes (i.e., Witches of November). The classification scheme follows a 1-5 hierarchy with category 1 storms being the least severe and category 5storms the most severe. Winter storm/nor'easter category is determined through the development of an intensity index (I) from surface synoptic charts. The 1-5 scale classification scheme of the storm's intensity is determined from the sumof central low pressure difference from 1013 mb, the deepening rate (millibars per 12 hours) and the maximum pressure gradient in millibars per 1000 kilometers. A fivescale (1-5) duration factor (DF), inve... |
