Asymmetry of the Intertropical Convergence Zone Asymmetry of the Intertropical Convergence Zone There are a number of explanations of the asymmetry of the Intertropical Convergence Zone (ITCZ), known by sailors as The Doldrums. The ITCZ would be expected to overlie the geographic equator according to symmetric solar radiation. However, the ITCZ is mostly perennial in the northern hemisphere and in the eastern Pacific and Atlantic Oceans. It was originally explained by the asymmetrical distribution of continents. However, the distribution of land and ocean is severely asymmetric in the Indian Ocean, yet the ITCZ moves back and forth there between the southern and northern hemispheres. Continents surround
Blood rain unknown but it might be related to the monsoon as well, as Kerala is the first state that the southwest monsoon strikes together with Sri Lanka. Again, trade winds (SE and NE) converge at a region called the Inter-Tropical Convergence Zone (ITCZ), which is located close to Kerala and Sri Lanka, which might be another clue for this puzzle. Authors said their steps would be the analysis of intercontinental clouds using High-Efficiency Particulate Air Filters, using the similar DNA sequence based technique called “metagenomics”, which would reveal the entire microbial diversity of these clouds. While most ancient authors, such as
