WebThe Low Level Wind Shear (LLWS) tab displays the magnitude of non-convective wind shear below 2000 feet AGL. The wind shear values are a difference in wind speed (m/s) divided by the depth (m) of the shear layer, resulting in units of 1/s. Warmer colors, with values above around 0.12 /s, indicate areas with stronger wind shear. The LLWS tab ...
