Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age.
Historical Examples. 1  The present writer has collected several hundred local wind namesâand is constantly adding to the list. 2  Because local wind systems dominate the trade winds, these deserts are less stable than other deserts.
The gradient wind is the equilibrium wind for the three forces â centripetal acceleration, pressure gradient force and Coriolis (or geostrophic). It is roughly aligned with the isobars on the meteorological surface chart. The vector difference between the geostrophic and the gradient winds is the ageostrophic wind. Thus, ageostrophic movement is large for small-scale systems and small for large-scale systems.
