Intertropical Convergence Zone it is sometimes referred to as a monsoon trough, a usage more common in Australia and parts of Asia. In the seamen's speech, the zone is referred to as the doldrums because of its erratic (monotonous) weather patterns with stagnant calms and violent thunderstorms. The ITCZ appears as a band of clouds, usually thunderstorms, that encircle the globe near the Equator. In the Northern Hemisphere, the trade winds move in a southwestward direction from the northeast, while in the Southern Hemisphere, they move northwestward from the southeast. When the ITCZ is positioned north or south of the Equator, these directions
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
