LLJ over Maryland

Weather conditions favored the formation of low level jet. The lidar timeseries shows that after 0:00 UTC the boundary layer was inhomgeneous with stratification, as a result of LLJ activity in the boundary layer. The presence of the LLJ was also confirmed by the MDE Wind Profiler. From 00:38 to 3:00 UTC we observe a region of convergence, characterized by low wind speeds (~ 5 m/s) associated with a southerly wind shift, that results in aerosol lifting. After 3:00 UTC and around 1.25 km, a thick residual layer above the core of the low level jet is coincidental with directional shear.
