Tropical Cyclones and Drought Amelioration in the Gulf and Southeastern Coastal United States

Abstract Precipitation from land-falling tropical cyclones (TCs) has a significant hydroclimatic influence in the southeastern United States, particularly during drought years. The frequency with which TCs ended drought conditions was examined for southeastern coastal states from Texas to North Carolina during 1895–2011. The region was divided into the Gulf Coast states (GCS) and the southeastern Atlantic coast states (ACS). The spatiotemporal patterns of tropical cyclone drought busters (TCDBs) were analyzed. Larger-scale ocean–atmosphere influences on TCDBs were examined using chi-squared analysis. The ACS experienced TCDBs more frequently and farther inland compared to the GCS. The number of TCDBs has significantly increased with time in the ACS. TCDBs numbers in the GCS did not exhibit significant increases, but the area alleviated of drought conditions increased significantly in the last 117 years. The dominant larger-scale ocean–atmosphere forcing of TCDBs was a combination of a warm Atlantic Ocean [positive Atlantic multidecadal oscillation index (AMO+)] and weak westerlies [negative North Atlantic Oscillation index (NAO−)]. AMO+ leads to an increase in the number of TCs throughout the North Atlantic basin, and NAO− increases the likelihood of TC landfall by controlling the steering of TCs toward the southeastern United States.

Shellfish seasonality studies are summarized in this article, which presents the results of analysis at 94 sites in nine southeastern states. All but six of the sites are middens or shell lenses composed of marine or brackish water species (M. mercenaria, R. cuneata, D. variabilis). Shells in those sites along the Atlantic coast were collected from fall to early spring, while shells in sites on the Gulf coast were collected during early spring to summer. Freshwater shellfish middens in four states have been investigated and consistently indicated collection during warm weather. The uniformity of the results indicates that the variation in species used, techniques used, sample sizes, or geography have no noticeable negative impact on the usefulness of the results. It is argued that shellfish were a staple in the diet of many prehistoric horticultural peoples in spite of the fact that they are a dietary supplement for modern hunters and collectors.

The Arbitral Tribunal of the Permanent Court at The Hague, by its award of the 7th of last September, in the case of the North Atlantic Coast Fisheries, brought to a close a controversy which in its various phases has been an almost constant source of vexatious dispute between the United States and Great Britain for the past seventy years.A treaty, granting exceptional rights, such as that which this Tribunal was called upon to consider, is peculiarly susceptible to different interpretations as the course of time brings new conditions not contemplated by its negotiators. The relations of the parties are changed. A liberty which at the date of the treaty was considered indispensable may become worthless, while one which was deemed insignificant may in years assume a place of vital importance to the beneficiaries under the grant. This change of conditions and of the value of rights has been especially true of the liberties acquired by the United States for its inhabitants under the first article of the Treaty of October 20, 1818.

AbstractFrom the 344 state climate divisions in the conterminous United States, nine distinct regions of warm-season drought variability are identified using principal component analysis. The drought metric used is the Palmer hydrological drought index for the period 1895–2008. The focus of this paper is multidecadal drought variability in the Southeast (SEUS) and eastern Gulf South (EGS) regions of the United States, areas in which the low-frequency forcing mechanisms of warm-season drought are still poorly understood. Low-frequency drought variability in the SEUS and EGS is associated with smoothed indexed time series of major ocean–atmosphere circulation features, including two indices of spatiotemporal variability in the North Atlantic subtropical anticyclone (Bermuda high). Long-term warm-season drought conditions are significantly out of phase between the two regions. Multidecadal regimes of above- and below-average moisture in the SEUS and EGS are closely associated with slow variability in sea surface temperatures in the North Atlantic Ocean and with the summer mean position and mean strength of the Bermuda high. Multivariate linear regression indicates that 82%–92% of the low-frequency variability in warm-season moisture is explained by two of the three leading principal components of low-frequency variability in the climate indices. The findings are important for water resource managers and water-intensive industries in the SEUS and EGS. The associations identified in the paper are valuable for enhanced drought preparedness and forecasting in the study area and potentially for global models of coupled ocean–atmosphere variability.
