Tracking Pressure Perturbations Resulting From Thunderstorm Complexes

By Alexander Jacques, MesoWest/SynopticLabs and Atmospheric Sciences

Two strong thunderstorm complexes moved across the north-central plains of the United States late on August 11 into August 12, 2011. This animation shows research efforts to detect and evaluate large mesoscale surface pressure perturbation features generated by these complexes. The detected positive (red contours) and negative (blue contours) perturbations are determined from perturbation analysis grids, generated every 5 minutes, using USArray Transportable Array surface pressure observations (circle markers). Best-track paths for perturbations are shown via the dotted trajectories. To identify physical phenomena associated with the perturbations, conventional radar imagery was also leveraged to identify regions of thunderstorm and precipitation activity. It can be seen here that two distinct thunderstorm complexes are co-located with several of the detected pressure perturbation feature.
