The ITCZ from Africa to the Eastern Pacific continues to display anomalous high rainfall through April. If this pattern continues it would enhanced the liklihood of TC development in both basins.
The below image is a GOES-12 infrared imagery showing the location of the intertropical front (ITCZ). The ITCZ actually crosses Northern South America where it is called the Near-equatorial convergence zone or NECZ.
The second image shows a GOES-12 infrared imagery and location of ITCZ one year ago from today. The image reveals a less active ITCZ in 2007 than 2008 in the Eastern Pacific. While in the Atlantic, the ITCZ is at about the same orientation in both years.
The image below is one week's of rainfall accumulation measured by TRMM. The red line represents the moisture gradient, the area where the enviroment would favor tropical wave formation. The greater the moisture gradient between the dry Sahara and moist Guinea Coast, the more frequent occurance of strong tropical waves.
TRMM also revealed the vertical structure of TC NEOGURI on April 17. Notice the very high thunderstorm towers in the eye wall (the region surrounding the eye). These towers aid in the intensification of TCs.
