A hurricane needs humidity to develop. Humidity is the amount of  water in the air. A hurricane starts off as a series of  thunderstorms which intensify as it moves over the â¦ warm humid sea.  The humidity continues to grow over the sea. Any sort of decrease  or increase in humidity can change the strength of a hurricane.
A cyclone is formed over tropical seas. Winds from opposite directions meet. This air is heated by the warm seas and so evaporates moisture from the ocean. This warm air rises up rapidly, cools and condenses to form clouds and produces an area of very low pressure.When moisture and air mix, it makes a collection of thunderstorms from which a cyclone can develop.Water needs to be at least 26 degrees warm so a tropical cyclone can develop. More air is sucked in to take its place, and it too is heated and rises rapidly.his air is heated by the warm seas and so evaporates moisture from the ocean.
