Abstract

Most hurricane-related deaths are caused by flooding and, as a result, accurate forecasting of rainfall can have a profound impact on reducing loss of life as well as property damages resulting from hurricanes. Quantitative relationships between atmospheric moisture and rainfall have been examined during the landfall of three Atlantic hurricanes in the study, with Geographic Information System and high temporal resolution remote sensing data used and time lags between atmospheric moisture and rainfall taken into account. Results show that 1) atmospheric moisture and rainfall-related variables can be accurately gauged by satellite at any given place and provide approximate estimations for the average and total amounts of rainfall after three and six hours, and 2) the intensity of rainfall was weaker but lasted longer over land than over ocean.
