What causes tropical storms

What causes tropical cyclones?

• Dry desert regions

• Low pressure areas

• High pressure areas

• Cold ocean water

Describe three conditions needed for the formation of tropical cyclones and explain why the conditions are needed.

• Low wind speeds, low pressure, and warm ocean water. These conditions are not suitable for cyclone formation.

• Low wind speeds, high pressure, and cold ocean water. These conditions are needed to create a calm environment for cyclones to form.

• High wind speeds, low pressure, and warm ocean water. These conditions provide the energy for increased evaporation and storm development.

• High wind speeds, high pressure, and cold ocean water. These conditions prevent the formation of cyclones.

What weather conditions would you expect to encounter as a tropical cyclone passes over an area?

• Snowfall, calm winds, and cold temperatures

• Heavy rain, strong winds, and sunny intervals

• Clear skies, light winds, and warm temperatures

• Hailstorms, foggy conditions, and moderate winds

Why does a tropical cyclone lose its strength when it passes over land or a cold ocean current?

• The presence of high-altitude clouds

• The absence of warm ocean water as an energy source

• Because of the decrease in air pressure

• Due to the lack of wind shear

What are the typical characteristics of a tropical cyclone?

• Low humidity, calm winds, and cold temperatures

• High humidity, strong winds, and warm temperatures

• Clear skies, light winds, and moderate temperatures

• Hailstorms, foggy conditions, and heavy winds

Explain the impact of sea surface temperature on the intensity of tropical cyclones.

• Higher sea surface temperatures lead to weaker tropical cyclones

• Lower sea surface temperatures have no effect on the intensity of tropical cyclones

• Warmer sea surface temperatures fuel the development and intensification of tropical cyclones

• Colder sea surface temperatures cause tropical cyclones to dissipate quickly

What impact does the presence of an eye have on the strength of a tropical cyclone?

• The eye of a tropical cyclone weakens its intensity

• The eye of a tropical cyclone has no effect on its strength

• The eye of a tropical cyclone indicates a rapid intensification phase

• The eye of a tropical cyclone signifies its dissipation

How warm must the water be in order to form a tropical cyclone?

• 26-27 degrees Celsius

• 20-21 degrees Celsius

• 35-36 degrees Celsius

• 18-19 degrees Celsius

What do you call the center of a tropical cyclone?

• Eyewall

• Eye

• Heart

• Core

What happens when a tropical cyclone makes landfall?

*Landfall refers to the point where the center of a tropical cyclone meets the coastline.

• Weakens

• Picks up speed

• Stronger wind speeds

• Smaller storm surge
