Help - 850 mb Moisture Transport

The 850 mb moisture transport is the product of the wind speed (m s-1) and the mixing ratio (g g-1) at 850 mb. Values are scaled by factor of 100, such that a 40 kt (~20 m s-1) wind speed and a 12 g kg-1 mixing ratio (0.012 g g-1) results in a moisture transport of 24 m s-1 (the first pink shade in the color fill). High values of moisture transport have been related to heavy rainfall potential with convective systems.
