Note that toward the end of the animation on 10 September, a plume of dry continental air (TPW values of 30-40 mm, blue to cyan enhancement)<\/em> was entrained into the circulation of downgraded Tropical Depression Gabrielle as the cyclone moved away from the US East Coast.<\/p>\n

As Gabrielle began to move northeastward across the Atlantic Ocean, it traveled along the north wall of the Gulf Stream — the warm waters in that region likely helped to prolong Gabrielle’s duration at tropical depression intensity. An 8-day composite of MODIS Sea Surface Temperature (SST) data (below)<\/strong><\/em> revealed that water temperatures along the axis of the Gulf Stream were still as warm as 83\u00c2\u00ba F (28\u00c2\u00baC) during early September.<\/p>\n

The IDEA<\/strong><\/a> MODIS Aerosol Optical Depth (AOD) product (above)<\/strong><\/em> indicated that the “dry air plume” moving eastward off the US coast also contained elevated levels of particle pollution, which was supported by the large number of surface AirNOW<\/strong><\/a> <\/strong>sites (below)<\/strong><\/em> from Georgia to North Carolina that reported “Moderate” concentrations of particle pollution (51-100 \u00c2\u00b5g per cubic meter, yellow circles)<\/em>.<\/p>\n
