英文摘要 | Studies have quantified the contribution of tropical cyclones (TCs) towards seasonal precipitation, but limited analysis is available on TCs’ contribution towards seasonal streamflow over the southeastern and southcentral United States (SESC). Using an extensive network of hydroclimatic data that consists of 233 TC tracks and daily precipitation and streamflow, we estimate TCs contribution towards precipitation and streamflow during the hurricane season over the SESC. We found that TCs account for 12% of seasonal streamflow and 6% of seasonal precipitation over the region. Florida, North Carolina, and Louisiana have the highest fractional occurrence of TC-generated annual maximum precipitation (∼20-32%) and streamflow (∼15-27%). We also found the fractional occurrence of TCs associated with peak-over threshold precipitation (streamflow) events ranges from 5-8% in coastal regions (10-20% over FL and 5-10% over coastal NC). Increased antecedent moisture results in increased TCs led contribution on streamflow leading to different land-surface responses for similar hurricane events. |
