Book excerpt: Excerpt from Surface Winds of the Southeastern Tropical Atlantic Ocean Marsden square quadrants 0012 and 0011 and the northern halves of Marsden square quad rants 3012, 3011, 3002, and 3001 or about 10% of the Wind field's area during 40% of the year. In contrast to the small seasonal movement of the oceanic high pressure cells, the strong thermal reaction of the African continent causes its low pressure cell to move from a Northern Summer latitude of lat 25° N to its Southern Summer latitude of 15° S. Through out the year, this low pressure cell affects sur face winds of the area just offshore from Cape Palmas to Luanda. Over these coastal waters this strong low pressure cell changes the flow of the South Atlantic High from southeasterly to predominantly southerly and southwesterly. The west-east oriented area formed by Mars den square quadrants 3011, 3002, and 3001 has only a small seasonal change in wind speed. A comparison of the wind fields for February and August shows that this area has only a 0 to 5% change in frequency of Wind speed greater than 10 knots; the area of zero change is about one-half Marsden square quadrant in size and is centered over Marsden square quad rant 3002. In contrast, a sharp gradient of seasonal change in wind frequency occurs to the north and south, and (more steeply) to the northeastward towards Port Harcourt. Also centered over Marsden square quadrant 3002 is an area of convergence (trewartha, 1968, p. 100, Fig. Which is about the size of one Marsden square quadrant. This area of convergence persists months after the larger itc, earlier described, has moved northward out of the Wind field. Further study could pos sibly correlate other interface parameters with this coincident area of small change of con vergence and frequency of Wind speed.
