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.
Local Surface winds are sometimes more a function of Temperature Differences between mountain tops and lower elevations than overriding Synoptic winds. These winds are sometimes called Mountain Winds as they occur most frequently in mountainous areas, meteorologist call them Katabatic or Anabatic Winds.Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column.Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a down slope wind.Katabatic wind may range over fairly large areas as in the case of the Santa Anna winds experienced throughout southern California during certain times of the year.inds can be derived from a number of different meteorological phenomena that are either caused by large scale synoptic pressure and temperature differences or by local temperature and pressure differences.
