Atmospheric blocking events enhance springtime transport of black carbon emissions to the Arctic snow from Russian cropland burning
Figure 1: 900 mb March 2003–2015: The average transport time (hours) difference maps between blocked and nonblocked conditions. The difference map color bars have been created so that red grid cells indicate transport under blocked conditions was quicker compared to the blue color indicating that transport was under nonblocked conditions.
Figure 2: 900 mb April 2006 blocking event transport time to the snow-covered Arctic within 96 hours of burning (a) and corresponding trajectories (b). A subset of successful trajectories (c) is shown over European Russia to highlight the anticyclonic winds associated with the April 2006 blocking event.
