meridional flow

[mə′rid·ē·ən·əl ′flō]
(meteorology)

Observations show that during the first synoptic event discussed above a relatively weaker westerly (no significant differences in meridional flow were observed) and low-level moisture flux of 50 g [kg.sup.-1] m [s.sup.-1] were present, in combination with an easterly moisture flow at midlevels; and during the second synoptic event a deeper and more intense westerly moisture flux of 80-100 g [kg.sup.-1] m [s.sup.-1].
