18 Questions
What is the minimum wind speed that characterizes strong winds in tropical cyclones?
Greater than 119km/h
What is the primary factor that contributes to the formation of storm surges?
Low pressure caused by the tropical cyclone
What is the minimum temperature required for the formation of tropical cyclones?
Greater than 26 degrees Celsius
What is the role of trade winds in the formation of tropical cyclones?
They cause the storm to spin due to the earth's rotation
In what direction do tropical cyclones spin north of the equator?
Counter-clockwise
What is the process by which air rises and pressure decreases in a tropical cyclone?
Air continues to rise and the pressure starts to decrease at higher altitudes
What is the characteristic of the center of a tropical cyclone?
Calm winds surrounded by a spinning vortex of high winds and heavy rain
What is the primary factor that determines the speed of winds in a tropical cyclone?
The amount of warm air sucked in from the sea surface
What are the two necessary conditions for the formation of a tropical cyclone?
Large, warm ocean (temps exceed 26.5 ℃) and strong winds in the troposphere needed to draw warm air up from the ocean surface
What is the primary mechanism that drives the formation of a tropical cyclone, and how does it relate to the Coriolis force?
The primary mechanism that drives the formation of a tropical cyclone is the mixing of warm air from thunderstorms and the deep, warm ocean surface, which begins to rise and create low pressure. The Coriolis force, caused by the Earth's rotation, then takes over, making the storm spin.
How do tropical cyclones affect the surrounding environment, and what are the resulting hazards?
Tropical cyclones bring strong winds, storm surges, intense rainfall, and landslides, causing destruction, floods, and loss of life.
What is the role of the warm ocean surface in the formation of a tropical cyclone, and what is the minimum temperature required?
The warm ocean surface provides the energy and moisture needed for the formation of a tropical cyclone, with a minimum temperature of 26.5°C required.
How does the Coriolis force influence the direction of spin in a tropical cyclone, and what is the resulting impact on the surrounding environment?
The Coriolis force causes tropical cyclones to spin, with storms north of the equator spinning counter-clockwise and those south of the equator spinning clockwise, resulting in different impacts on the surrounding environment depending on the direction of spin.
What is the relationship between the strength of a tropical cyclone and the speed of its winds?
The strength of a tropical cyclone is directly related to the speed of its winds, with stronger storms having faster wind speeds.
How do the hazards associated with tropical cyclones vary depending on the location and intensity of the storm?
The hazards associated with tropical cyclones, such as strong winds, storm surges, and intense rainfall, vary in severity and impact depending on the location and intensity of the storm.
What is the relationship between the formation of a tropical cyclone and the movement of air in the troposphere?
The formation of a tropical cyclone is driven by the movement of air in the troposphere, with warm air rising and creating low pressure, and cooler air sinking to replace it.
How does the rotation of the Earth influence the formation and behavior of tropical cyclones?
The rotation of the Earth influences the formation and behavior of tropical cyclones through the Coriolis force, which causes the storm to spin and affects its path.
What is the role of low pressure in the formation of a tropical cyclone, and how does it relate to the movement of air?
Low pressure is a critical component of the formation of a tropical cyclone, as it drives the movement of air upwards, creating the conditions necessary for the storm to develop and intensify.
Learn about the formation and dangers of tropical cyclones, including strong winds, storm surges, intense rainfall, and landslides. Understand how they bring destruction and chaos to coastal areas.
