The intertropical convergence zone (ITCZ) is a permanent low-pressure feature that lies on the meteorological equator. It is characterisied by lots of cloud cover and precipitation (Andrews et al., 2003). The ITCZ plays a significant role in the climate and weather events in the tropics. The clouds created by the ITCZ also provide an important form of albedo in the tropics (Waliser and Gautier, 1993),which has an effect on global climate. Tropical events such as monsoon and cyclones occur in the ITCZ and are products of the unique convection system found around the ITCZ (Yancheva et al., 2007, Ferreira and Schubert, 1997).The ITCZ is a product of humid trade winds from the northern and southern hemisphere converging and then rising. This rising of humid air usually results in precipitation over the tropics(Waliser and Somerville, 1994). This rising of the humid air acts as the driving force in the Hadley Cell (Waliser and Somerville, 1994). The ITCZ is a product of high levels of solar radiation and high amounts of latent heat released from the ocean (Andrews et al., 2003). It is important to realize that the ITCZ moves throughout the year depending on the seasons, it is likely to be found in the southern hemisphere in the southern hemisphere summer and in the northern hemisphere during the northern hemispheres summer. However the ITCZ is more likely to be found in the Northern hemisphere (Waliser and Somerville, 1994). The ITCZ plays a large role in many of the climatic
