How do we measure typhoons?

Front

What does the Saffr Simpson scale measure?

Back

The power of the hurricane

Answer explanation

The Saffir-Simpson scale measures the power of a hurricane, specifically its potential damage based on wind speed. Therefore, the correct answer is 'The power of the hurricane'.

Front

Which category on the Saffir-Simpson scale indicates the most severe hurricane?

Back

Category 5

Answer explanation

Category 5 on the Saffir-Simpson scale indicates the most severe hurricane, with wind speeds exceeding 157 mph. It represents the highest level of damage potential, making it the most dangerous category.

Front

Primary factor used to classify hurricanes on the Saffir-Simpson scale?

Back

Wind speed

Answer explanation

The Saffir-Simpson scale classifies hurricanes primarily based on wind speed. This scale categorizes storms from Category 1 to 5, with higher categories indicating stronger winds and greater potential for damage.

Front

At what wind speed does a tropical storm become a Category 1 hurricane on the Saffir-Simpson scale?

Back

74 mph

Answer explanation

A tropical storm becomes a Category 1 hurricane when wind speeds reach 74 mph. This is the threshold defined by the Saffir-Simpson scale, which categorizes hurricanes based on their wind speed.

Front

Minimum category on the Saffir-Simpson scale causing significant structural damage?

Back

Category 3

Answer explanation

Category 3 hurricanes can cause significant structural damage, including severe damage to roofs and walls. Categories 1 and 2 typically result in less severe impacts, while Category 4 and 5 cause catastrophic damage.

Front

Which of the following is NOT a factor considered in the Saffir-Simpson scale? Storm surge height, Wind speed, Rainfall amount, Central pressure

Back

Rainfall amount

Answer explanation

The Saffir-Simpson scale measures hurricane intensity based on wind speed, storm surge height, and central pressure. Rainfall amount is not a factor in this scale, making it the correct answer.

Front

How many categories are there on the Saffir-Simpson scale?

Back

5

Answer explanation

The Saffir-Simpson scale categorizes hurricanes into 5 categories, ranging from Category 1 to Category 5, based on their wind speeds and potential damage. Therefore, the correct answer is 5.

Front

What normally happens to air pressure as a typhoon approaches?

Back

It drops suddenly and a lot

Answer explanation

As a typhoon approaches, the air pressure drops suddenly and significantly. This drop is due to the intense low-pressure system associated with the storm, which leads to strong winds and severe weather conditions.

Front

The eye wall brings...

Back

The most violent conditions

Answer explanation

The eye wall of a storm is characterized by the most violent conditions, including intense winds and heavy rainfall, making it the most dangerous part of a hurricane.

Front

What is the main purpose of the Saffir-Simpson scale?

Back

To classify the intensity of hurricanes

Answer explanation

The Saffir-Simpson scale is primarily used to classify the intensity of hurricanes based on their sustained wind speeds, helping to assess potential damage and inform preparedness efforts.
