due in large measure to the very high summer temperatures in this locale 

 with resultant high water-vapor capacity. It is also quite striking that 

 the general level of A^o is 25 at 30 iV" units above that of the west coast. 

 The high A^o values of the Gulf regions are also found at Miami (MIA), 

 figure 4.20, although the moderating effect of continual onshore winds 

 produces less pronounced vertical gradients and smaller diurnal ranges 

 than Brownsville, particularly during the summer months.
