B: China and India both have a population around 1.5 billion people so in total they have around 3 billion people combined! That is more than the continent of Africa and North America combined!
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
