Observation

This question was very popular among the candidates.  Most of those who answered the question scored high marks.  A few of them had no idea of what Inter-Tropical Convergence Zone (ITCZ) is.  The expected notes on Inter-Tropical Convergence Zone (ITCZ) include:

-               tropical northeast trades are dry and dusty;
-               southeast trades and southwest monsoons are wet and moisture laden;
-               the two winds converge over the Equatorial Trough along a line of discontinuity called ITD or the ITCZ;
-               in West Africa, ITCZ lies close to the sea in December and January;
-               the ITCZ moves to 20oN in August.
