Description :
The AA. identify the frequency of tropical cyclones (TCs) that abruptly end drought conditions (i.e., drought busters, or DB) and determine possible influences of coupled ocean–atmosphere teleconnections on the likelihood of a TC-induced DB (TCDB). Using the HURDAT database and Palmer Drought Severity Indexes from 1950 through 2008, they identified every TCDB for 31 climate divisions in the southeastern Atlantic United States. They present the spatial patterns of the total number of TCDBs and the percentage of all droughts ended by TCs using choropleth maps. To determine what teleconnections influenced TCDBs, they used logistic regression analysis and included multiple synoptic-scale circulation indexes as predictor variables. In addition, they used a Fisher's exact test to examine the association between the North Atlantic Oscillation (NAO) and TCDBs.
