How do the global winds affect cyclones in the bay of Bengal?(Answer with 3 points)
Answers
Answer:
The elements in group one of the periodic table (with the exception of hydrogen - see below) are known as the alkali metals because they form alkaline solutions when they react with water. This group includes the elements lithium, sodium, potassium, rubidium, and francium. Each of these elements has just one valence electron, which means that they form only weak metallic bonds. As a result, they are relatively soft and have low melting points.
The single valence electron is easily lost, making these metals highly reactive. They react vigorously with both air and water - when sodium comes into contact with water, for example, it reacts violently to form sodium hydroxide and hydrogen. The heat of the reaction actually ignites the hydrogen! Alkali metals also readily combine with the elements of group seventeen (chlorine, fluorine, bromine etc.) to form stable ionic compounds like sodium chloride.

Answer:
The BoB is potentially a very energetic region for development of cyclones, though only 5% of the total global tropical cyclones occur here. Cyclones are formed over this region mainly during the pre-monsoon and post-monsoon season among which the later are more devastating in nature.
Genesis of cyclonic systems depends upon many Oceanic and Atmospheric parameters. But in this context, more significant role is played by the atmospheric conditions (Grey (1968) ) over the warm oceanic region. Few such atmospheric situations for cyclone development are:
1. Low level relative vorticity (should be high)
2. Vertical wind shear (should be low)
3. Relative humidity of middle troposphere (should be high)
4. Middle tropospheric thermal instability (should be high)
etc..
