winter winds are predominantly from the north or northwest, while spring and 

 summer winds are from the south or southwest (Chermock 1974). 



Persistent high winds from the north and northwest during the winter tend 

 to depress the water level in much of the bay and concurrently cause a 

 buildup of waves along the south and southeast shores where wind fetch length 

 is great. Under these conditions, severe erosion may occur along the north- 

 ern shore of Morgan Peninsula (Pensacola quadrangle) (Figure 7). 



During the summer and occasionally in the winter persistent strong south 

 and southwesterly winds (13-28 km/hr, 8-17 mi/hr) cause a decrease in water 

 level, especially in the lower bay. Waves and tides then build up in the 

 upper bay, causing severe erosion along the western shore and lower Mobile 

 Delta (Mobile quadrangle). These variations in water level cause complex 

 currents that complicate the normal circulation within the bay.
