Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a requirement for cyclones to form?
A
High humidity
B
Intensity
C
Weak wind force
D
Separation of air masses
Explanation: 

Detailed explanation-1: -The middle atmosphere must be relatively humid at a height of about 5, 000 metres (16, 000 feet) above the surface. The developing system must be at least 500 km (300 miles) away from the Equator.

Detailed explanation-2: -Energy from the Sun evaporates water into water vapour, which can easily be moved around the atmosphere. The water vapour eventually condenses back into water releasing energy as heat. This heat is a key component in the formation of storms.

Detailed explanation-3: -They are classified as follows: Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.

Detailed explanation-4: -High sea temperatures of at least 27°C. Converging winds near the ocean surface forcing air to rise and form storm clouds. Winds that do not vary greatly with height-known as low wind shear. Sufficient distance from the equator for a spin such as the Coriolis force to take effect.
