**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.
